<div>
<div class="kekeke">JSAFK</div>
</div>
</body>
</html>
For getting a JSAFK element in this doc, using XPath, can I just write //*div[#class=kekeke] instead full XPath?
// is short for /descendant-or-self::node()/. So...
This XPath,
//div[#class='kekeke']
will select all such div elements in the document:
<div class="kekeke">JSAFK</div>
This XPath,
//div[#class='kekeke']/text()
will select all text nodes under all such div elements in the document:
JSAFK
there is something wrong in "
//*div[#class=kekeke]
you can't use * and div together. if you want to have a shorter path.
you can write like this
//div[#class="kekeke"]/text()

Hello I have this HTML:
<div class="_3Vhpd"><span>Your commerce Data</span>
<a class="n3G0C" href='http://www.webadress.......'><span>Some Text</span</a>
</div>
I tried to obtain the tag as follow:
parser.xpath('//div[contains(#class,"_3Vhpd")]//following-sibling::*[a[#class="n3G0C"]]/#href ')
but I received none '[]'. Maybe because is not just after div but after a span...
First, you sample html doesn't have a class="n3G0C", but assuming you fix it, this xpath expression should work:
//div[contains(#class,"_3Vhpd")]//following-sibling::a/#href
Output:
http://www.webadress.......
With the help of this SO question I have an almost working xpath:
//div[contains(#class, 'measure-tab') and contains(., 'someText')]
However this gets two divs: in one it's the child td that has someText, the other it's child span.
How do I narrow it down to the one with the span?
<div class="measure-tab">
<!-- table html omitted -->
<td> someText</td>
</div>
<div class="measure-tab"> <-- I want to select this div (and use contains #class)
<div>
<span> someText</span> <-- that contains a deeply nested span with this text
</div>
</div>
To find a div of a certain class that contains a span at any depth containing certain text, try:
//div[contains(#class, 'measure-tab') and contains(.//span, 'someText')]
That said, this solution looks extremely fragile. If the table happens to contain a span with the text you're looking for, the div containing the table will be matched, too. I'd suggest to find a more robust way of filtering the elements. For example by using IDs or top-level document structure.
You can use ancestor. I find that this is easier to read because the element you are actually selecting is at the end of the path.
//span[contains(text(),'someText')]/ancestor::div[contains(#class, 'measure-tab')]
You could use the xpath :
//div[#class="measure-tab" and .//span[contains(., "someText")]]
Input :
<root>
<div class="measure-tab">
<td> someText</td>
</div>
<div class="measure-tab">
<div>
<div2>
<span>someText2</span>
</div2>
</div>
</div>
</root>
Output :
Element='<div class="measure-tab">
<div>
<div2>
<span>someText2</span>
</div2>
</div>
</div>'
You can change your second condition to check only the span element:
...and contains(div/span, 'someText')]
If the span isn't always inside another div you can also use
...and contains(.//span, 'someText')]
This searches for the span anywhere inside the div.
What is Valid Xpath for link extract by div class name?
Here is html code:
<div class="poster">
<a href="/title/tt2091935/mediaviewer/rm4278707200?ref_=tt_ov_i"> <img alt="Mr. Right Poster" title="Mr. Right Poster" src="http://ia.media-imdb.com/images/M/MV5BOTcxNjUyOTMwOV5BMl5BanBnXkFtZTgwMzUxMDk4NzE#._V1_UX182_CR0,0,182,268_AL_.jpg" itemprop="image">
</a> </div>
I want to know exact Xpath as if i found href link.
I try with //a/#href[#class='poster'] but it's doesn't work
The <div> contains the <a> so you can use that to navigate:
//div[#class='poster']/a/#href
Remember that the "poster" class is defined on the <div> not on the <a> so that's where you need to apply the predicate.
//div returns all <div> elements
[#class='poster'] is a predicate that filters by class
/a returns all <a> elements that are children of those <div>s
/#href gives us the attribute we want
Depending on the system you're using you might need to wrap the whole expression in text() in order to bring back the attribute data rather than the DOM node.
<article class='article-contents'>
<div class='summary'>xxxx</div>
<p>xxxxxx</p>
<table>...</table>
<p>....</p>...
</article>
I have a html structure like above, i'd like to skip pass <div class='summary'> and get the whole content inside article section using Xpath structure.
You could use a query like this:
//article[#class='article-contents']/node()[not(local-name()='div' and #class='summary')]
This should select all child nodes of the article excluding the summary div.
Take a look at the sample XML below--
<div id="main">
<div id="1">
Some random text
</div>
<div id="2">
Some random text
</div>
<div id="3">
Some random text
</div>
<p> Some more random text</p>
<div id="4">
Some random text
</div>
</div>
Now, how do I find out the number of divs within the main div using Xquery? And how to do this in XPath?
You can use the following XPath:
count(div[#id="main"]/div)
The function count does the counting, the main div is selected by its id.
The XPath expressions below can be used both in XPath and XQuery. This is so, because XPath (2.0) is a proper subset of XQuery.
Use:
count(/*//div)
If "the main div" isn't the top element of the XML document, and this is the only div whose id attribute has string value of "main", use:
count((//div[#id='main'])[1]//div)
If it is guaranteed that the div children of the "main div" dont have div descendents, use:
count((//div[#id='main'])[1]/div)
Do note: The XPath pseudo-operator // can be very inefficient -- this is why, always try to avoid using it, whenever the structure of the XML document is statically known and specific paths can be used.
