I need help with xpath expressions used in Orbeon Forms. I am passing values to a web service and need to load the result of it to a static image. So for the calculated value of it I use follow
concat(
'http://192.168.25.14:8084/OrbeonRouter/rest/qr?type=1&title=',
xxf:instance('fr-form-instance')/VARASection/ctrlTitle,
'&docID=',
xxf:instance('fr-form-instance')/VARASection/docID
)
I am passing form field values for title and docID parameters of my service. And I need to replace the white spaces that fall in between words (not trailing or leading spaces but spaces that falls in between title) of the xxf:instance('fr-form-instance')/VARASection/ctrlTitle string.
I even tried normalize-space(xxf:instance('fr-form-instance')/VARASection/ctrlTitle) but it didn't work.
You can use the encode-for-uri() function for this:
concat(
'http://192.168.25.14:8084/OrbeonRouter/rest/qr?type=1&title=',
encode-for-uri(xxf:instance('fr-form-instance')/VARASection/ctrlTitle),
'&docID=',
encode-for-uri(xxf:instance('fr-form-instance')/VARASection/docID)
)

I am facing a problem with my data, in my data other than alphanumeric characters are there in a column field, where for EX in Name column: Ravicￌhandr￢an (￢ￌ￮`) like these many characters are there. I need a result like Ravichandran. How can I achieve this? Is there any way to remove in transformer stage.
I tried Convert function in Transformer stage, but problem in using Convert, I am not sure about these unknown characters, I have shown above is just example.
My Requirement is, other than alphanumeric must be removed. And the Balance string should be the same.
How can I get this done?
The following Convert function can be used in Transformer stage to remove any kind of unknown/special characters from the column.
**Convert(Convert('ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789 ','', Column_Name1),'',Column_Name1)
Ex : Convert(Convert('ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789 ','', to_txm.SourceCode),'',to_txm.SourceCode)**
I need a a regular expression to allow only one character for a textbox. Actually i want to validate a text filed to enter a single charecter for Initial (for name)
In a regular expression, '.' (dot) matches a single character.
If you want to be sure that this single character is alphabetic, use:
[a-zA-Z]
or in a posix system: [:alpha:]
Now, to know exactly how to implement it, we need to know in which language your code is written.
For a starter, have a look to
http://en.wikipedia.org/wiki/Regular_expression
You can set the textbox property MaxLength to 1 and use a regex to validade if a letter.
I have a link in an apex report which takes the user to different page, and it passes some values to the new page. The button is set to a url because there are too many items being passed, but I don't think that would matter anyway:
f?p=&APP_ID.:27:&SESSION.::&DEBUG.::P27_1,P27_2,P27_3,P27_4,P27_5:0,#1#,#2#,#3#,#NULL#
The #1#, etc. are columns being passed. Everything seems to work correctly except that the data being passed often contains a colon (:), which messes up Apex's built in colon structure by cutting off anything in the new page's item that happens after the colon (including the colon itself) as well as messing up any fields after that. For example: #2# has a colon in it, so P27_3, 4, and 5 will not be filled with values.
I've tried manually replacing the colon with a '%3a' (the url encoding for colon), but it doesn't seem to work.
Try using UTL_URL.ESCAPE() to escape URL special characters and UTL_URL.UNESCAPE() to un-escape them back.
You can also try APEX_UTIL.URL_ENCODE() but you need to use one or the other, i.e. either UTL or APEX_UTIL.
I am going to pass string value between pages.
The value contains "&" character.
Since the values are split using "&", so the value is chopped.
How can I escape this special character?
use URL encoding...
for ex: if you want '&' .. use '& amp;' (no spaces)
Recommended way is to use
Uri.EscapeUriString(stringToEscape)
method which does this for you.

I need to locate the node within an xml file by its value using XPath.
The problem araises when the node to find contains value with whitespaces inside.
F.e.:
<Root>
<Child>value</Child>
<Child>value with spaces</Child>
</Root>
I can not construct the XPath locating the second Child node.
Simple XPath /Root/Child perfectly works for both children, but /Root[Child=value with spaces] returns an empty collection.
I have already tried masking spaces with %20, & #20;, & nbsp; and using quotes and double quotes.
Still no luck.
Does anybody have an idea?
Depending on your exact situation, there are different XPath expressions that will select the node, whose value contains some whitespace.
First, let us recall that any one of these characters is "whitespace":
-- the Tab
-- newline
-- carriage return
' ' or -- the space
If you know the exact value of the node, say it is "Hello World" with a space, then a most direct XPath expression:
/top/aChild[. = 'Hello World']
will select this node.
The difficulties with specifying a value that contains whitespace, however, come from the fact that we see all whitespace characters just as ... well, whitespace and don't know if a it is a group of spaces or a single tab.
In XPath 2.0 one may use regular expressions and they provide a simple and convenient solution. Thus we can use an XPath 2.0 expression as the one below:
/*/aChild[matches(., "Hello\sWorld")]
to select any child of the top node, whose value is the string "Hello" followed by whitespace followed by the string "World". Note the use of the matches() function and of the "\s" pattern that matches whitespace.
In XPath 1.0 a convenient test if a given string contains any whitespace characters is:
not(string-length(.)= stringlength(translate(., '
','')))
Here we use the translate() function to eliminate any of the four whitespace characters, and compare the length of the resulting string to that of the original string.
So, if in a text editor a node's value is displayed as
"Hello World",
we can safely select this node with the XPath expression:
/*/aChild[translate(., '
','') = 'HelloWorld']
In many cases we can also use the XPath function normalize-space(), which from its string argument produces another string in which the groups of leading and trailing whitespace is cut, and every whitespace within the string is replaced by a single space.
In the above case, we will simply use the following XPath expression:
/*/aChild[normalize-space() = 'Hello World']
Try either this:
/Root/Child[normalize-space(text())=value without spaces]
or
/Root/Child[contains(text(),value without spaces)]
or (since it looks like your test value may be the issue)
/Root/Child[normalize-space(text())=normalize-space(value with spaces)]
Haven't actually executed any of these so the syntax may be wonky.
Locating the Attribute by value containing whitespaces using XPath
I have a input type element with value containing white space.
eg:
<input type="button" value="Import Selected File">
I solved this by using this xpath expression.
//input[contains(#value,'Import') and contains(#value ,'Selected')and contains(#value ,'File')]
Hope this will help you guys.
"x0020" worked for me on a jackrabbit based CQ5/AEM repository in which the property names had spaces. Below would work for a property "Record ID"-
[(jcr:contains(jcr:content/#Record_x0020_ID, 'test'))]
did you try #x20 ?
i've googled this up like on the second link:
try to replace the space using "x0020"
this seems to work for the guy.
All of the above solutions didn't really work for me.
However, there's a much simpler solution.
When you create the XMLDocument, make sure you set PreserveWhiteSpace property to true;
XmlDocument xmldoc = new XmlDocument();
xmldoc.PreserveWhitespace = true;
xmldoc.Load(xmlCollection);
