Is there any way, how I can to identify two xpath values in one.
I have text located somewhere on web page, on another page it exists in same element, but has different xpath. See below two variants:
Variant1: .//*[#id='quote_1']/div[2]/div[1]/div[1]/div[1]/p[2]
Variant2: .//*[#id='quote_1']/div/div[1]/div[1]/div[1]/div[2]/div[3]/span[2]
I'm looking how I can combine these two xpath's to one like the following:
xpath = Variant1 or Variant2;
Thank you.
The XPath union operator | is probably what you are asking for:
.//*[#id='quote_1']/div[2]/div[1]/div[1]/div[1]/p[2]
|
.//*[#id='quote_1']/div/div[1]/div[1]/div[1]/div[2]/div[3]/span[2]
This XPath expressions selects the union of two nodesets:
All nodes selected by .//*[#id='quote_1']/div[2]/div[1]/div[1]/div[1]/p[2]
All nodes selected by .//*[#id='quote_1']/div/div[1]/div[1]/div[1]/div[2]/div[3]/span[2]

I have the following XML structure
<Root>
<BundleItem>
<Item>1</Item>
<Item>2</Item>
<Item>3</Item>
</BundleItem>
<Item>4</Item>
<Item>5</Item>
<Item>6</Item>
<BundleItem>
<Item>7</Item>
<Item>8</Item>
<Item>9</Item>
</BundleItem>
</Root>
And by providing the following xPath
//Item[1]
I am selecting
<Item>1</Item>
<Item>4</Item>
<Item>7</Item>
My goal is to select only <Item>1</Item> or <Item>7</Item> regardless of the parent element where they are found and only depending on the position, which i am providing in the xPath.
Is it possible to do that only by using the position and without providing additional criterias in the xPath ?
//Item[1] selects the all the first child elements that are <Item/> regardless of their parent.
To get the two items you are looking for you could use //Item[text() = 1 or text() = 7].
A good tutorial can be found at w3schools.com and you can play with XPath expressions over your XML input here. (I am not affiliated with either of these resources but find them useful.)
I'm trying to select an folder and its descendants from a JCR with XPath. I can select the folder easily enough:
//content/documents/folder-name
I can select its descendants too:
//content/documents/folder-name//*
However, I can't figure out how to get both. I've tried several things. These select nothing:
//content/documents/folder-name | //content/documents/folder-name//*
//content/documents/folder-name(. | *)
//content/documents/folder-name/(. | *)
//content/documents/folder-name/descendant-or-self
//content/documents/folder-name/descendant-or-self::node()
These both throw a javax.jcr.query.InvalidQueryException:
//content/documents/folder-name[. | *]
//content/documents/folder-name/[. | *]
Obviously I'm terrible at XPath. Please help.
Edit: I was using the // prefix because I didn't realize I could use /jcr:root/content instead. I have the same problem with that, however.
You can combine two XPaths using the union operator:
xpath1 | xpath2
However, your first XPath,
//content/documents/folder-name
does select the folder-name element(s), which includes the descendants of the element.
If you want the folder-name elements to be first in a list, followed by their descendants, you could combine as follows:
//content/documents/folder-name | //content/documents/folder-name//*
//content/documents/folder-name/descendant-or-self::node() looks correct to me (without seeing your XML input), though //content/documents/folder-name/descendant-or-self::* is probably better.
Certainly if //content/documents/folder-name selects something then ``//content/documents/folder-name/descendant-or-self::*` should also select something.
In XPath 2.0 you can do //content/documents/folder-name/(.|descendant::*) but although it's shorter, it seems clumsier to me than using the descendant-or-self axis.
I am trying to automate some tests using selenium webdriver. I am dealing with a third-party login provider (OAuth) who is using duplicate id's in their html. As a result I cannot "find" the input fields correctly. When I just select on an id, I get the wrong one.
This question has already been answered for JQuery. But I would like an answer (I am presuming using Xpath) that will work in Selenium webdriver.
On other questions about this issue, answers typically say "you should not have duplicate id's in html". Preaching to the choir there. I am not in control of the webpage in question. If it was, I would use class and id properly and just fix the problem that way.
Since I cannot do that. What options do I get with xpath etc?
you can do it by driver.find_element_by_id, for example ur duplicate "duplicate_ID" is inside "div_ID" wich is unique :
driver.find_element_by_id("div_ID").find_element_by_id("duplicate_id")
for other duplicate id under another div :
driver.find_element_by_id("div_ID2").find_element_by_id("duplicate_id")
This XPath expression:
//div[#id='something']
selects all div elements in the XML document, the string value of whose id attribute is the string "something".
This Xpath expression:
count(//div[#id='something'])
produces the number of the div elements selected by the first XPath expression.
And this XPath expression:
(//div[#id='something'])[3]
selects the third (in document order) div element that is selected by the first XPath expression above.
Generally:
(//div[#id='something'])[$k]
selects the $k-th such div element ($k must be substituted with a positive integer).
Equipped with this knowledge, one can get any specific div whose id attribute has string value "something".
Which language are you working on? Dublicate id's shouldn't be a problem as you can virtually grab any attribute not just the id tag using xpath. The syntax will differ slightly in other languages (let me know if you want something else than Ruby) but this is how you do it:
driver.find_element(:xpath, "//input[#id='loginid']"
The way you go about constructing the xpath locator is the following:
From the html code you can pick any attribute:
<input id="gbqfq" class="gbqfif" type="text" value="" autocomplete="off" name="q">
Let's say for example that you want to consturct your xpath with the html code above (Google's search box) using name attribute. Your xpath will be:
driver.find_element(:xpath, "//input[#name='q']"
In other words when the id's are the same just grab another attribute available!
Improvement:
To avoid fragile xpath locators such as order in the XML document (which can change easily) you can use something even more robust. Two xpath locators instead of one. This can also be useful when dealing with hmtl tags that are really similar. You can locate an element by 2 of its attributes like this:
driver.find_element(:id, 'amount') and driver.find_element(xpath: "//input[#maxlength='50']")
or in pure xpath one liner if you prefer:
//input[#id="amount" and #maxlength='50']
Alternatively (and provided your xpath will only return one unique element) you can move one more step higher in the abstraction level; completely omitting the attribute values:
//input[#id and #maxlength]
It's not listed at http://selenium-python.readthedocs.io/locating-elements.html but I'm able access a method find_elements_by_id
This returns a list of all elements with the duplicate ID.
links = browser.find_elements_by_id("link")
for link in links:
print(link.get_attribute("href"))
you should use driver.findElement(By.xpath() but while locating element with firebug you should select absolute path for particular element instead of getting relative path this is how you will get the element even with duplicate ID's
I have those two RxPaths which I need to be written in one expresion:
/td[2]/a[1]/tag[1]
and
/td[2]/a[1]
So basically I need to select path with 'tag' element if exists, if not than to select 'a' element.
something like:
if exist /td[2]/a[1]/tag[1] select /td[2]/a[1]/tag[1]
else select /td[2]/a[1]
Those elements need to have innertext attribute with some value in them, so I tried:
/td[2]/descendant::node()[#innertext!='']
but it won't work...
Also those elements are at the bottom of hierarchy so if is there any way to just select first element at lowest level.
I managed to solve this with an regex at the end of my Xpath expression.
/dom/body/div[#id='isc_0']/div/div[#id='isc_B']/div[#id='isc_C']/div[#id='isc_10']/div/div/iframe/body/table/tbody/tr/td[1]/a[#innertext='any uri item']/../../td[2]/*[#innertext~'[^ ]+']
Sorry for misunderstanding with problem...

So basically I need to select path
with 'tag' element if exists, if not
than to select 'a' element. something
like:
if exist
/td[2]/a[1]/tag[1]
select
/td[2]/a[1]/tag[1]
else select
/td[2]/a[1]
I highly doubt that the top element of the document is a td. Don't use /td -- it means you want to select the top element of the document and this top element must be a td .
Also, /td[2] never selects anything, because a (wellformed) XML document has exactly one top element.
Use:
someParentElement/td[2]/a[1]/tag[1]
|
someParentElement/td[2]/a[1][not(someParentElement/td[2]/a[1]/tag[1])]
Those elements need to have innertext
attribute with some value in them
Use:
someParentElement/td[2][.//#innertext[normalize-space()]]/a[1]/tag[1]
|
someParentElement/td[2]
[.//#innertext[normalize-space()]]/a[1]
[not(someParentElement/td[2]
[.//#innertext[normalize-space()]]/a[1]/tag[1])]
Also those elements are at the bottom
of hierarchy so if is there any way to
just select first element at lowest
level.
This is not clear. Please, clarify.
All "leaf" elements can be selected using the following XPath expression:
//*[not(*)]
The elements selected don't have any children-elements, but may have other children (such as text-nodes, PIs, comments) and attributes.
Besides all those good advices from #Dimitre, I want to add that a parent will always come before (in document order) than a child, so you could use this XPath expression:
(/real-path-from-root/td[2]/a[1]
|
/real-path-from-root/td[2]/a[1]/tag[1])[last()]
You could do this without | union set operator in XPath 1.0, but it will end up very unreadable... Of course, in XPath 2.0 you could just do:
(/real-path-from-root/td[2]/a[1]/(.|tag[1]))[last()]
I try to write xpath expressions so that my tests won't be broken by small design changes. So instead of the expressions that Selenium IDE generates, I write my own.
Here's an issue:
//input[#name='question'][7]
This expression doesn't work at all. Input nodes named 'question' are spread across the page. They're not siblings.
I've tried using intermediate expression, but it also fails.
(//input[#name='question'])[2]
error = Error: Element (//input[#name='question'])[2] not found
That's why I suppose Seleniun has a wrong implementation of XPath.
According to XPath docs, the position predicate must filter by the position in the nodeset, so it must find the seventh input with the name 'question'. In Selenium this doesn't work. CSS selectors (:nth-of-kind) neither.
I had to write an expression that filters their common parents:
//*[contains(#class, 'question_section')][7]//input[#name='question']
Is this a Selenium specific issue, or I'm reading the specs wrong way? What can I do to make a shorter expression?
Here's an issue:
//input[#name='question'][7]
This expression doesn't work at all.
This is a FAQ.
[] has a higher priority than //.
The above expression selects every input element with #name = 'question', which is the 7th child of its parent -- and aparently the parents of input elements in the document that is not shown don't have so many input children.
Use (note the brackets):
(//input[#name='question'])[7]
This selects the 7th element input in the document that satisfies the conditions in the predicate.
Edit:
People, who know Selenium (Dave Hunt) suggest that the above expression is written in Selenium as:
xpath=(//input[#name='question'])[7]
If you want the 7th input with name attribute with a value of question in the source then try the following:
/descendant::input[#name='question'][7]
