I want to write a test to check if a webelement with a specified text is not present on a page. This is the code for the method doing the job:
public boolean checkOfAanvraagIsOpgevoerd (String titel)
{
String quote = "\"";
String titelMetQuotes = quote + titel +quote;
titelMetQuotes = "dierdieboeboe";
boolean isOpgevoerd=false;
try {
driver.findElement(By.xpath(".//*[#id='listRequests']//h4/a[contains(text(),"+titelMetQuotes+")]"));
isOpgevoerd=true;
} catch (NoSuchElementException NE) {
NE.printStackTrace();
}
return isOpgevoerd;
}
Although I'm absolutely sure that there is no a tag on the page wich contains the text "dierdieboeboe" still the catch block is skipped. When I replace for instance h4 in h5 in the xpath expression the NoSuchElementException is thrown as expected. It seems that the contains part in the expression is ignored.
Try this (note the single quotes around the actual text):
By.xpath("//*[#id='listRequests']//h4/a[contains(text(),'"+titelMetQuotes+"')]")
contains is a function that takes two strings. Hence the text of your variable titelMetQuotes needs to be quoted. Obviously, in this case it is easier to use single quotes.
Additionally, the variable name (titel with quotes) is quite misleading because it actually has no quotes for another flaw in the code:
String titelMetQuotes = quote + titel +quote;
titelMetQuotes = "dierdieboeboe";
The second line simply overwrites the quoted title with a non quoted string.
Finally, you don't need the leading dot in your xpath expression in order to locate the first element of any kind with id listRequests

I am using Java Properties to read a properties file. Everything is working fine, but Properties silently drops the backslashes.
(i.e.)
original: c:\sdjf\slkdfj.jpg
after: c:sdjfslkdfj.jpg
How do I make Properties not do this?
I am using the code prop.getProperty(key)
I am getting the properties from a file, and I want to avoid adding double backslashes
It is Properties.load() that's causing the problem that you are seeing as backslash is used for a special purpose.
The logical line holding all the data
for a key-element pair may be spread
out across several adjacent natural
lines by escaping the line terminator
sequence with a backslash character,
\.
If you are unable to use CoolBeans's suggestion then what you can do is read the property file beforehand to a string and replace backslash with double-backslash and then feed it to Properties.load()
String propertyFileContents = readPropertyFileContents();
Properties properties = new Properties();
properties.load(new StringReader(propertyFileContents.replace("\\", "\\\\")));
Use double backslashes c:\\sdjf\\slkdfj.jpg
Properties props = new Properties();
props.setProperty("test", "C:\\dev\\sdk\\test.dat");
System.out.println(props.getProperty("test")); // prints C:\dev\sdk\test.dat
UPDATE CREDIT to #ewh below. Apparently, Windows recognises front slashes. So, I guess you can have your users write it with front slashes instead and if you need backslashes afterwards you can do a replace. I tested this snippet below and it works fine.
Properties props = new Properties();
props.setProperty("test", "C:/dev/sdk/test.dat");
System.out.println(props.getProperty("test")); // prints C:/dev/sdk/test.dat
Use forward slashes. There is never a need in Java to use a backslash in a filename.
In case you really need a backslash in a properties file that will be loaded (like for a property that is not a file path) put \u005c for each backslash character.
The backslash is treated specially in properties files as indicated in the document provided by #unhillbilly.
#EJP: Backslash is definitely needed if, for example, you wanted to store an NTLM login id in a properties file, where the format is DOMAIN\USERNAME with a backslash. This type of property is not a filename so forward slashes will not work.
Edit: #Max Nanasy: From the document (java.util.Properties load javadoc) mentioned above (emphasis mine)
The method does not treat a backslash character, '\', before a non-valid escape character as an error; the backslash is silently dropped. For example, in a Java string the sequence "\z" would cause a compile time error. In contrast, this method silently drops the backslash. Therefore, this method treats the two character sequence "\b" as equivalent to the single character 'b'
For me, I always had trouble with backslashes in the properties file (even with double backslash '\\') unless I specified the unicode.
Replace \ with \\ as below:
c:\sdjf\slkdfj.jpg
to
c:\\sdjf\\slkdfj.jpg
In addition to Bala R's answer I have the following solution to even keep the newline-semantic of backslashes at the end of a line.
Here is my code:
private static Reader preparePropertyFile(File file) throws IOException {
BufferedReader reader = new BufferedReader(new FileReader(file));
StringBuilder result = new StringBuilder();
String line;
boolean endingBackslash = false;
while ((line = reader.readLine()) != null) {
line = line.trim();
if (endingBackslash) {
// if the line is empty, is a comment or holds a new property
// definition the backslash found at the end of the previous
// line is not for a multiline property value.
if (line.isEmpty()
|| line.startsWith("#")
|| line.matches("^\\w+(\\.\\w+)*=")) {
result.append("\\\\");
}
}
// if a backslash is found at the end of the line remove it
// and decide what to do depending on the next line.
if (line.endsWith("\\")) {
endingBackslash = true;
line = line.substring(0, line.length() - 1);
} else {
endingBackslash = false;
}
result.append(line.replace("\\", "\\\\"));
}
if (endingBackslash) {
result.append("\\\\");
}
return new StringReader(result.toString());
}
private static Properties getProperties(File file) throws IOException {
Properties result = new Properties();
result.load(preparePropertyFile(file));
return result;
}
The following code will help :
BufferedReader metadataReader = new BufferedReader(new InputStreamReader(new FileInputStream("migrateSchemaGenProps.properties")));
Properties props = new Properties();
props.load(new StringReader(IOUtils.getStringFromReader(metadataReader).replace("\\", "/")));
It is not realy a good thing to use backslashes in a property-file, as they are the escape character.
Nevertheless: a Windows user will trend to use them in any path... Therefore, in a single line thanks apache common IO:
params.load(new StringReader(IOUtils.toString(paramFile.toURI(), null).replaceAll("\\\\", "/")));
you triple use the backslash to get one:
for example:
key=value1\\value2
in the properties file will turn to
key=value1\value2
in the java Properties object
I have tried to know the reason in online but i didnt get it.
I want to know the reason why '%s' used in xpath instead of giving text message
I hope some one can help me on this.
see my scenario:
By.xpath(("//div[contains(text(),'%s')]/following-sibling::div//input"))
It's called wildcard.
E.g. you have
private final String myId = "//*[contains(#id,'%s')]";
private WebElement idSelect(String text) {
return driver.findElement(By.xpath(String.format(myId, text)));
}
Then, you can make a function like:
public void clickMyId(idName){
idSelect(idName.click();
}
And call
clickMyId('testId');
The overall goal of the %s is not using the string concatenation, but to use it injected into a string.
Sometimes, there are many locators for web elements which are of same kind, only they vary with a small difference say in index or String.
For e.g., //div[#id='one']/span[text()='Mahesh'] and
//div[#id='one']/span[text()='Jonny']
As it can been seen in the above example that the id is same for both the element but the text vary.
In that case, you can use %s instead of text. Like,
String locator = "//div[#id='one']//span[text()='%s']";
private By pageLocator(String name)
{
return By.xpath(String.format(locator, name));
}
So in your case,
By.xpath(("//div[contains(text(),'%s')]/following-sibling::div//input"))
the text is passed at runtime as only the text vary in the locator.
'%s' in XPath is used as String Replacement.
Example:
exampleXpath = "//*[contains(#id,'%s')]"
void findElement(String someText)
{
driver.findElement(By.xpath(String.format(exampleXpath, someText)));
}
So it will replace %s with someText passed by user.
I was trying to do autocomplete for my input box. When user start typing "I, then I should exactly search the keyword what user has typed ("I). When keys pressed, I was getting the string value as "\"I. How can i do the search based on what user has entered without stripping off any character from the string. Pls provide me any suggestion to help my issue.
Sample Code
public JsonResult AutoBibs(string searchTerm)
{
model = (from line in db.BibContents
where (line.Value.StartsWith(searchTerm) || line.Value.Contains(" " + searchTerm))
select new PoDetails
{
BibId = line.BibId
}).ToList();
return model;
}
The " always appends with an Escape character while processing the String variables in C# i.e. it appends "\" at the beginning. It would not change your functionality and you can still continue with your Auto Complete feature. Generally you can find this during in DEBUG mode only.
Read this MSDN article for more details.
I can't figure out how to search for text containing single quotes using XPATHs.
For example, I've added a quote to the title of this question. The following line
$x("//*[text()='XQuery looking for text with 'single' quote']")
Returns an empty array.
However, if I try the following
$x("//*[text()=\"XQuery looking for text with 'single' quote\"]")
It does return the link for the title of the page, but I would like to be able to accept both single and double quotes in there, so I can't just tailor it for the single/double quote.
You can try it in chrome's or firebug's console on this page.
Here's a hackaround (Thanks Dimitre Novatchev) that will allow me to search for any text in xpaths, whether it contains single or double quotes. Implemented in JS, but could be easily translated to other languages
function cleanStringForXpath(str) {
var parts = str.match(/[^'"]+|['"]/g);
parts = parts.map(function(part){
if (part === "'") {
return '"\'"'; // output "'"
}
if (part === '"') {
return "'\"'"; // output '"'
}
return "'" + part + "'";
});
return "concat(" + parts.join(",") + ")";
}
If I'm looking for I'm reading "Harry Potter" I could do the following
var xpathString = cleanStringForXpath( "I'm reading \"Harry Potter\"" );
$x("//*[text()="+ xpathString +"]");
// The xpath created becomes
// //*[text()=concat('I',"'",'m reading ','"','Harry Potter','"')]
Here's a (much shorter) Java version. It's exactly the same as JavaScript, if you remove type information. Thanks to https://stackoverflow.com/users/1850609/acdcjunior
String escapedText = "concat('"+originalText.replace("'", "', \"'\", '") + "', '')";!
In XPath 2.0 and XQuery 1.0, the delimiter of a string literal can be included in the string literal by doubling it:
let $a := "He said ""I won't"""
or
let $a := 'He said "I can''t"'
The convention is borrowed from SQL.
This is an example:
/*/*[contains(., "'") and contains(., '"') ]/text()
When this XPath expression is applied on the following XML document:
<text>
<t>I'm reading "Harry Potter"</t>
<t>I am reading "Harry Potter"</t>
<t>I am reading 'Harry Potter'</t>
</text>
the wanted, correct result (a single text node) is selected:
I'm reading "Harry Potter"
Here is verification using the XPath Visualizer (A free and open source tool I created 12 years ago, that has taught XPath the fun way to thousands of people):
Your problem may be that you are not able to specify this XPath expression as string in the programming language that you are using -- this isn't an XPath problem but a problem in your knowledge of your programming language.
Additionally, if you were using XQuery, instead of XPath, as the title says, you could also use the xml entities:
"" for double and ' for single quotes"
they also work within single quotes
You can do this using a regular expression. For example (as ES6 code):
export function escapeXPathString(str: string): string {
str = str.replace(/'/g, `', "'", '`);
return `concat('${str}', '')`;
}
This replaces all ' in the input string by ', "'", '.
The final , '' is important because concat('string') is an error.
Well I was in the same quest, and after a moment I found that's there is no support in xpath for this, quiet disappointing! But well we can always work around it!
I wanted something simple and straight froward. What I come with is to set your own replacement for the apostrophe, kind of unique code (something you will not encounter in your xml text) , I chose //apos// for example. now you put that in both your xml text and your xpath query . (in case of xml you didn't write always we can replace with replace function of any editor). And now how we do? we search normally with this, retrieve the result, and replace back the //apos// to '.
Bellow some samples from what I was doing: (replace_special_char_xpath() is what you need to make)
function repalce_special_char_xpath($str){
$str = str_replace("//apos//","'",$str);
/*add all replacement here */
return $str;
}
function xml_lang($xml_file,$category,$word,$language){ //path can be relative or absolute
$language = str_replace("-","_",$language);// to replace - with _ to be able to use "en-us", .....
$xml = simplexml_load_file($xml_file);
$xpath_result = $xml->xpath("${category}/def[en_us = '${word}']/${language}");
$result = $xpath_result[0][0];
return repalce_special_char_xpath($result);
}
the text in xml file:
<def>
<en_us>If you don//apos//t know which server, Click here for automatic connection</en_us> <fr_fr>Si vous ne savez pas quelle serveur, Cliquez ici pour une connexion automatique</fr_fr> <ar_sa>إذا لا تعرفوا أي سرفير, إضغطوا هنا من أجل إتصال تلقائي</ar_sa>
</def>
and the call in the php file (generated html):
<span><?php echo xml_lang_body("If you don//apos//t know which server, Click here for automatic connection")?>
I'm working on converting code from Ruby to Node.js. I came across these lines at the end of a function and I'm curious what the original developers were trying to accomplish:
url = url.gsub "member_id", "member_id__hashed"
url = url.gsub member_id, member_id_hashed
url
I'm assuming that url at the end is Ruby's equivalent to return url;
as for the lines with gsub, from what I've found online that's the wrong syntax, right? Shouldn't it be:
url = url.gsub(var1, var2)?
If it is correct, why are they calling it twice, once with quotes and once without?
gsub does a global substitute on a string. If I had to guess, the URL might be in the form of
http://somewebsite.com?member_id=123
If so, the code has the following effect:
url.gsub "member_id", "member_id__hashed"
# => "http://somewebsite.com?member_id__hashed=123"
Assuming member_id = "123", and member_id_hashed is some hashed version of the id, then the second line would replace "123" with the hashed version.
url.gsub member_id, member_id_hashed
# => "http://somewebsite.com?member_id__hashed=abc"
So you're going from http://somewebsite.com?member_id=123 to http://somewebsite.com?member_id__hashed=abc
Documentation: https://ruby-doc.org/core-2.6/String.html#method-i-gsub
I'm assuming that the url at the end is Ruby's equivalent to return url;
If that code is part of a method or block, indeed, the line url is the value returned by the method. This is because by default a method in Ruby returns the value of the last expression that was evaluated in the method. The keyword return can be used (as in many other languages) to produce an early return of a method, with or without a return value.
that's the wrong syntax, right? shouldn't it be
url = url.gsub(var1, var2)?
The arguments used to invoke a method in Ruby may stay in parentheses but they may, as well, be listed after the method name, without parentheses.
Both:
url = url.gsub var1, var2
and
url = url.gsub(var1, var2)
are correct and they produce the same result.
The convention in Ruby is to not put parentheses around method arguments but this is not always possible. One such case is when one of the arguments is a call of another method with arguments.
The parentheses are then used to make everything clear both for the interpreter and the readers of the code.
If it is correct, why are they calling it twice, once with quotes and once without?
There are two calls of the same method, with different arguments:
url = url.gsub "member_id", "member_id__hashed"
The arguments of url.gsub are the literal strings "member_id" and "member_id__hashed".
url = url.gsub member_id, member_id_hashed
This time the arguments are the variables member_id and member_id_hashed.
This works the same in JavaScript and many other languages that use double quotes to enclose the string literals.
String#gsub is a method of class String that does search & replace in a string and returns a new string. It's name is short of "global substitute" (it replaces all occurrences). To replace only the first occurrence use String#sub.
