What happens when I apply following-sibling::*[1] to the last child?
What happens when I apply
following-sibling::*[1] to the last
child?
Answer: it gets evaluate to an empty node-set, because there is no more following siblings.
If you want to get the following sibling of the context node or following sibling of context node parent otherwise, the rigth axis is following, as in:
following::*[1]
It will get you the first sibling to the current node.
Here is an example:
<Root>
<Div id="Hey">
Test1
</Div>
<Div>
Test2
</Div>
<Div>
Test3
</Div>
</Root>
XPath:
/Root/Div[#id = 'Hey']/following-sibling::*[1]
/Root/Div[#id = 'Hey'] will get you the Div with id=Hey and /following-sibling::*[1] will then get you the first sibling so in total you would get the Div with the text "Test2".
Update: I apologize (see comment), but this: /Root/Div[3]/following-sibling::*[1] will just return a empty list. (Div[3] is the last child)

I am searching a solution to remove a string value obtained on a webpage with an XPath function.
I have this :
<div id="article_body" class="">
This my wonderful sentence, however here the string i dont want :
<br><br>
<div class="typo">Found a typo in the article? Click here.
</div>
</div>
So at the end I would have
This my wonderful sentence, however here the string i dont want :
I get the text with
//*[#id="article_body"]
Then I try to use replace:
//replace('*[#id="article_body"]','Found a typo in the article? ', )
But it doesn't work, so I think it's because I'm a newbie with XPath...
How can I do that please?
It appears that you are getting the computed string value of the selected div element.
The string-value of an element node is the concatenation of the string-values of all text node descendants of the element node in document order.
If you don't want to include the text() from the descendant nodes, and only want the text() that are immediate children of the div, then adjust your XPath:
//*[#id="article_body"]/text()
Otherwise, you could use substring-before():
substring-before(//*[#id="article_body"], 'Found a typo in the article?')
There are a number of labels, I want to specify them in xpath and then grab the text after them, example:
<div class="info-row">
<div class="info-label"><span>Variant:</span></div>
<div class="info-content">
<p>750 ml</p>
</div>
</div>
So in this case, I want to say "after the span named 'Variant' grab the p tag:
Result: 750ml
I tried:
//span[text()='Variant:']/following-sibling::p
and variations of this but to no avail.
'following-sibling' function selects all siblings after the current node,
there no siblings for span with text 'Variant:', and correct to search siblings for span parent.
Here is an example which will work
//span[text()='Variant:']/ancestor::div[#class="info-label"]/following-sibling::div/p
I need to extract all children which have nodes with some text. Html structure might be the following:
<div>
<div>
A
</div>
<p>
<b>A</b>
</p>
<span>
B
</span>
</div>
I need to extract child nodes which have "A" text. It should return div and p nodes
I tried the following xpaths:
./*/*[contains(text(), 'A')]
./*/*[./*[contains(text(), 'A')]]
but the first one returns only div with "A" text and the second one returns only p with "A" text
Is it possible to construct xpath which will return both children?
Node containing "A" text might be at any level in the child node
If you need XPath that returns both child nodes, try to use
./*/*[contains(., "A")]
I suspect contains() is wrong here, unless you really want to select a node whose value is "HAT" as well as one whose value is "A".
Try
*/*[normalize-space(.)='A']
Given the following HTML:
$content =
'<html>
<body>
<div>
<p>During the interim there shall be nourishment supplied</p>
</div>
<div>
<p>During the interim there shall be interim nourishment supplied</p>
</div>
<div>
<ul><li>During the interim there shall be nourishment supplied</li></ul>
</div>
</body>
</html>';
I want all the nodes containing the word "interim" but not if the word "interim" is part of a link element.
The nodes I would expect back are the first P node and the LI node only.
I've tried the following:
'//*/text()[not(a) and contains(.,"interim")]'
... but this still returns the A and also returns part of it's parent P node (the part after the A), neither of which are desired. You can see my attempt here: https://glot.io/snippets/ehp7hmmglm
If you use the XPath expression //*[not(self::a) and not(a) and text()[contains(.,"interim")]] then you get all elements that do not contain an a element, are not a elements and contain a text node child containing that word.
basically i want to select a node (div) in which it's children node's(h1,b,h3) contain specified text.
<html>
<div id="contents">
<p>
<h1> Child text 1</h1>
<b> Child text 2 </b>
...
</p>
<h3> Child text 3 </h3>
</div>
i am expecting, /html/div/ not /html/div/h1
i have this below, but unfortunately returns the children, instead of the xpath to the div.
expression = "//div[contains(text(), 'Child text 1')]"
doc.xpath(expression)
i am expecting, /html/div/ not /html/div/h1
So is there a way to do this simply with xpath syntax?
The following expression gives a node (div) in which any children nodes (not just h1,b,h3) contain specified text (not the div itself):
doc.xpath('//div[.//*[contains(text(), "Child text 1")]]')
you can refine that and return the only the div with the id contents like in your example:
doc.xpath('//div[#id="contents" and .//*[contains(text(), "Child text 1")]]')
It does not match, if the text is a text node of the div (directly inside the div), which is my interpretation of the question.
You could append "/.." to anchor back to the parent. Not sure if there's a more robust method.
expression = "//div[contains(text(), 'Child text 1')]/.."
