<div class="container">
<span class="price">
<bdi> 140 </bdi>
</span>
<span class="price">
<del>
<bdi>90</bdi>
</del>
<ins>
<bdi> 120 </bdi>
</ins>
</span>
</div>
I want to scrape a site which html formatting like below. Here I dont want to bdi tag value which is under del tag and want bdi tag value which is under span class and ins tag. Is there any path to figure it out?
Don't pretty much usual //span/ins/bdi/text() work for you?
This is "text of <bdi> which parent is <ins> which parent is <span>"?
CSS variant span>ins>bdi::text should also work I suppose.
Sorry, haven't noticed that you need two values. In that case .xpath('//bdi[not(parent::del)]/text()').extract() will work well.

I have the following HTML
<span class="medium bold day-time-clock">
09:00
<div class="tooltip-box first-free-tip ">
<div class="tooltip-box-inner">
<span class="fa fa-clock-o"></span>
Some more text
</div>
</div>
</span>
I want an XPath that only gets the text 09:00, not Some more text NOT using text()[1] because that causes other problems. My current XPath looks like this
("//span[1][contains(#class, 'day-time-clock')]/text()")
I want one that ignores this whole part of the HTML
<div class="tooltip-box first-free-tip ">
<div class="tooltip-box-inner">
<span class="fa fa-clock-o"></span>
Some more text
</div>
</div>
You can limit the level of descendant:: nodes with position().
So the following expression does work:
span/descendant::node()[2 > position()]
Adjust the number in the predicate to your needs, 2 is only an example. A disadvantage of this approach is that the counting of the descendants is only accurate for the first child in the descending tree.
Another approach is limiting the both: the ancestors and the descendants:
span/descendant::node()[3 > count(ancestor::*) and 1 > count(descendant::*)]
Here, too, you have to adjust the numbers in the predicates to get any useful results.
Use normalize-space() for select all non-whitespace nodes of the document:
//span[contains(#class, 'day-time-clock')]/text()[normalize-space()]
I think (if I understand you correctly) that
"..//div[contains(#class, 'tooltip-box')]/parent::span"
gets you there.
I'm trying to get the xpath of an element with a similar xpath to others but has a "neighbor" element that's different . Please see example below.
<div>
<div id='a'> </div>
<span> Text here </span> #this is what i'm trying to get
</div>
<div>
<div id='b'> </div>
<span> Text here </span>
</div>
I tried using //div//span, but this gives me the 2 spans. So i tried using //div//child::div[#id='a']//ancestor::div//child::span, but it doesn't look pleasant and looks repetitive. Does this have a better implementation?
try
//div[div[#id='a']]/span
it says get the span child node of all div nodes with child node div (with an #id equal to 'a').
After managing to import the filmography for any actor on rateyourmusic.com via
=importxml("https://rateyourmusic.com/films/cary_grant/","//li")
I couldn't figure out how to retrieve my own user rating for certain titles (which would also tell me which title in the list I've already seen).
As I'm still learning my ropes around the importxml command, all I found out is that they're under the 'film_cat_catalog_msg_1050' Xpath identifier(?), but fiddling with said command, all I could get on a separate column on my spreadsheet, was the standard 'rate' word so far - but no personal rating.
Could anyone help me with that, please?

As you have to be logged in in order to see said ratings, here's a screenshot for those who aren't members:
rateyourmusic.com filmography
Try it with this XPath query:
//span[#id="film_cat_catalog_msg_1050"]
Demo
As you have already guessed, we need something like starts-with since the numeric part is acutally variable:
//span[starts-with(#id, "film_cat_catalog_msg_")]
Demo 2
And putting it all together:
=importxml("https://rateyourmusic.com/films/cary_grant/","//span[starts-with(#id, 'film_cat_catalog_msg_')]")
There’s a document structured as follows:
<div class="document">
<div class="title">
<AAA/>
</div class="title">
<div class="lead">
<BBB/>
</div class="lead">
<div class="photo">
<CCC/>
</div class="photo">
<div class="text">
<!-- tags in text sections can vary. they can be `div` or `p` or anything. -->
<DDD>
<EEE/>
<DDD/>
<CCC/>
<FFF/>
<FFF>
<GGG/>
</FFF>
</DDD>
</div class="text">
<div class="more_text">
<DDD>
<EEE/>
<DDD/>
<CCC/>
<FFF/>
<FFF>
<GGG/>
</FFF>
</DDD>
</div class="more_text">
<div class="other_stuff">
<DDD/>
</div class="other_stuff">
</div class="document">
The task is to grab all the elements between <div class="lead"> and <div class="other_stuff"> except the <div class="photo"> element.
The Kayessian method for node-set intersection $ns1[count(.|$ns2) = count($ns2)] works perfectly. After substituting $ns1 with //*[#class="lead"]/following::* and $ns2 with //*[#class="other_stuff"]/preceding::*,
the working code looks like this:
//*[#class="lead"]/following::*[count(. | //*[#class="other_stuff"]/preceding::*)
= count(//*[#class="other_stuff"]/preceding::*)]/text()
It selects everything between <div class="lead"> and <div class="other_stuff"> including the <div class="photo"> element. I tried several ways to insert not() selector in the formula itself
//*[#class="lead" and not(#class="photo ")]/following::*
//*[#class="lead"]/following::*[not(#class="photo ")]
//*[#class="lead"]/following::*[not(self::class="photo ")]
(the same things with /preceding::* part) but they don't work. It looks like this not() method is ignored – the <div class="photo"> element remains in the selection.
Question 1: How to exclude the unnecessary element from this intersection?
It’s not an option to select from <div class="photo"> element excluding it automatically because in other documents it can appear in any position or doesn't appear at all.
Question 2 (additional): Is it OK to use * after following:: and preceding:: in this case?
It initially selects everything up to the end and to the beginning of the whole document. Could it be better to specify the exact end point for the following:: and preceding:: ways? I tried //*[#class="lead"]/following::[#class="other_stuff"] but it doesn’t seem to work.
Question 1: How to exclude the unnecessary element from this intersection?
Adding another predicate, [not(self::div[#class='photo'])] in this case, to your working XPath should do. For this particular case, the entire XPath would look like this (formatted for readability) :
//*[#class="lead"]
/following::*[
count(. | //*[#class="other_stuff"]/preceding::*)
=
count(//*[#class="other_stuff"]/preceding::*)
][not(self::div[#class='photo'])]
/text()
Question 2 (additional): Is it OK to use * after following:: and preceding:: in this case?
I'm not sure if it would be 'better', what I can tell is following::[#class="other_stuff"] is invalid expression. You need to mention the element to which the predicate will be applied, for example, 'any element' following::*[#class="other_stuff"], or just 'div' following::div[#class="other_stuff"].
I'm trying to extract the email text from a list but without success.
In particular I've used this code
//li/div/p//*[contains(., '#')]
but strangely it doesn't work! Could you help me?
Here's the code exemple
<li class="bgmp_list-item">
<h3 class="bgmp_list-placemark-title">

You're almost there but not quite. For the sample code the correct xpath would be
//p/text()[contains(.,'#')]
Not to reinvent the wheel here is a very good explanation on it on another answer
By using p//*[contains(., '#')] you apply the predicate on individual child elements of <p>, while there is no such child element because
the target email address text is direct child of <p>. This is one of the reason why the intial XPath didn't work. Applying the predicate on <p> directly should work :
//li/div/p[contains(., '#')]
but that will return the <p> element. If you need to return only the text node that contains email address, then the predicate should be applied on individual text nodes within <p>, as mentioned in the other answer :
//li/div/p/text()[contains(., '#')]
