I have this xpath:
.//*[#id='some_id']/td//div
and now I want to select any child of the div that is of certain type, for example every child that is either a label or span. Something like this
.//*[#id='some_id']/td//div/(label|span)/.......
but that is not valid xpath. How can I do that (wthout writing two full xpaths for the given 2 example for child types)
descendant:: finds on all level below, to find only children use
.//*[#id='some_id']/td//div/*[self::label or self::span]
you need to use
descendant::
to select child elements of particular element. look at the below example,
.//*[#id='some_id']/td//div/descendant::label[#class='some-class']
the above xpath will get all label with class "some-class" which is actually the child of ".//*[#id='some_id']/td//div/" element.
to find multiple child elements then use below xpath,
.//*[#id='some_id']/td//div/descendant::*[local-name()='label' or local-name='span']

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 am trying to find XPath of an element which has no attribute. It can only be identified by its parent's attribute. However, the parent also does not have unique attribute.
Eg: //*[#id="btn"][1]/ul/li[2]/a/span
Here there are 2 elements with id=btn. How do i get the 2nd element. The above syntax gives me 1st element.. However if i use:
//*[#id="btn"][2]/ul/li[2]/a/span
I get an error message
"The xpath expression '//*[#id="btn"][2]/ul/li[2]/a/span' cannot be evaluated or does not result in a WebElement "
Try this, you select those two first, then use brackets around and index them.
(//*[#id="btn"]/ul/li[2]/a/span)[2]
By the way, it's not a good practice to have multiple elements sharing same ids, if you are the developer, may consider change them.
I have several nodes with some particular attribute and I need to select one of them by index. For example I need to select second <div> with 'test' class - //div[#class='test'][2] doesn't work.
Is there a way to select node with some attribute by index ? How to do it?
This is a FAQ.
In XPath the [] operator has a higher precedence (binds stronger) than the // pseudo-operator.
Because of this, the expression:
//div[#class='test'][2]
selects all div elements whose class attribute is "test" and who (the div elements) are the second such div child of their parent. This is not what you want.
Use:
(//div[#class='test'])[2]
I believe per XML specification, attributes are not considered to have an order.
Note that the order of attribute specifications in a start-tag or empty-element tag is not significant.
See here
I think you'd be best of re-factoring your structure such that attribute order does not describe anything. If you can give any more details we might be able to offer suggestions.
EDIT: Re-reading your post, looks like you are trying to find node order and not attribute order. Node order is allowed and your syntax looks OK off-hand. What software are you doing this in?
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...

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 have an XPath that returns two items. I want to modify it so that it returns only the second, or the last if there are more than 2.
//a[#rel='next']
I tried
//a[#rel='next'][2]
but that doesn't return anything at all. How can I rewrite the xpath so I get only the 2nd link?
Found the answer in
XPATH : finding an attribute node (and only one)
In my case the right XPath would be
(//a[#rel='next'])[last()]
EDIT (by Tomalak) - Explanation:
This selects all a[#rel='next'] nodes, and takes the last of the entire set:
(//a[#rel='next'])[last()]
This selects all a[#rel='next'] nodes that are the respective last a[#rel='next'] of the parent context each of them is in:
//a[#rel='next'][last()] equivalent: //a[#rel='next' and position()=last()]
This selects all a[#rel='next'] nodes that are the second a[#rel='next'] of the parent context each of them is in (in your case, each parent context had only one a[#rel='next'], that's why you did not get anything back):
//a[#rel='next'][2] equivalent: //a[#rel='next' and position()=2]
For the sake of completeness: This selects all a nodes that are the last of the parent context each of them is in, and of them only those that have #rel='next' (XPath predicates are applied from left to right!):
//a[last()][#rel='next'] NOT equiv!: //a[position()=last() and #rel='next']
