I'm trying to rewrite someones library to parse some xml returned with requests. However they use lxml in a way I'm not used to. I believe it's using regular expression to find the data and while most of the library provided works, it doesn't work when the site being parsed has the file id in a list structure. Essnetially I get a page back and I'm looking for an id that matches the href athlete number. So say I want to just get id's for athlete 567377.
</div>
</a></div>
<ul class='list-entries'>
<li class='entity-details feed-entry' id='Activity-123120999590'>
<div class='avatar avatar-athlete avatar-default'>
<a class='avatar-content' href='/athletes/567377' >
</a>
</div>
</li>
<li class='entity-details feed-entry' id='Activity-16784940202'>
<div class='avatar avatar-athlete avatar-default'>
<a class='avatar-content' href='/athletes/5252525'>
</a>
</div>
The code:
lst_group_activity = parser.xpath(".//li[substring(#id, 1, 8)='Activity']")
Provides all list items perfectly but for all activities. I want to only have the one related to the right athlete. The library uses the following to use an #href to select the right athlete.
lst_athlethe_act_in_group_activity = parser.xpath(".//li[substring(#id, 1, 8)='Activity']/*[#href='/athletes/"+athlethe_id+"']/..")
However, this never seems to work. It finds the activity but then throws them all away.
Is there a better way to get this working? Any tutorial that can point me in the right direction to correlate to the next element.
The element with the href attribute isn't an immedite child of your li element, so your xpath is failing. You're matching:
.//li/*[#href="..."]
You want:
.//li/div/a[#href="..."]
(You could match * instead of a if you think another element might contain the href attribute, and you can match against .//li//a[#href="..."] if you think the path to the a element might not always be li/div/a).
So to find the li element:
parser.xpath(".//li[substring(#id, 1, 8)='Activity']/div/a[#href='/athletes/%s']/../.." % '5252525')
But you can also write that without the ../..:
parser.xpath(".//li[substring(#id, 1, 8)='Activity' and div/a/#href='/athletes/%s']" % '5252525')

I'm trying to get data from an HTML like this:
<div>
<h4 id='id1'>...</h4>
<ul>
<li></li>
<li></li>
</ul>
</div>
<div>
<h4 id='id2'>...</h4>
<ul> ... </ul>
</div>
The goal is to get the <li> values from every <h4>. To get this I've tried something like this:
divs = driver.find_elements_by_xpath("//div//h4[starts-with(#id,'id_')]")
for h4 in divs:
title = h4.text
# Get <li> from each div
for value in h4._parent.find_elements_by_tag_name('li'): #<-- It gives me all <li> in the page
# TODO ...
Here I'm trying to get all <h4> tags and then go to the parent (the <div>) and find the <li> tags existing only in that parent. But I retrieve all <li> tags.
I've searched over the internet and I've found a couple of question in StackOverflow like Get child element using xpath selenium python or selenium find child's child elements where it says to set the context, so I've tried this:
for value in h4._parent.find_elements_by_xpath('.//li'):
^
But it gives me the same numbers of elements.
So, I'm misunderstanding something?
Thanks in advance.
//div[./h4[starts-with(#id,'id')]]//li
To get all li's of all div that contains an element h4 with a certain id starting try this.
//div[./h4] basically means div with h4 element inside 1 layer deep.
Arendeep question is ok and it worked for me, but also I've noticed the problem I was having.
The element _parent seems to be the web page, not the parent element. And this is why the method find_element was getting all <li> tags from the page.
I can use accepted answer or also:
parent = h4.find_element_by_xpath('..')
for value in parent.find_elements_by_tag_name('li'):
# TODO
Where the xpath ('..') return the parent element.
This way gives me only child from the current element (maybe is an answer more accurate) but accepted answer also works on my scenario where I want all <li> tags dependant from the <h4>.
By the way I haven't found docs about _parent.
What is a good way to select multiple nodes from with in a node in a html code using xpath?
I have this code (actually this repeated 23 times);
<li>
<a class="Title" href="http://www.google.com" >Google</a>
<div class="Info">
<p>
text
</p>
<p class="Date">Status: Under development</p>
</div>
I am trying to get both Title and Date and have two different XPATH querys like this;
//a[#class="Title"]/#href
//p[#class="Date"]
But when I do this I get two returns with 23 and 22 values each. This is because at one point in the HTML code Date is not present. Therefore I would like to stay inside the li and search for Title and Date within that li so I can check if there are any values.
I changed my XPATH to this;
//li
In my return Element I can see that there are two sub elements, a and div but I cannot seem to figure out how I am supposed to handle what is inside the return Element?
When you want to search elements within the current node you need to start your Xpath pattern with a dot.
For example:
.//a[#class="Title"]/#href
.//p[#class="Date"]
<div id="tabs" class="clearfix">
<ul id="remove">
<li class="btn_arrow_tab left inactive">
<a href="#" class="doubleText">Pay Monthly <small>View standard rates and Bolt Ons</small>
</a>
</li>
<li class="btn_arrow_tab right inactive">
<a href="#" class="doubleText">Pay & Go<small>View standard rates and Bolt Ons</small>
</a>
</li>
</ul>
</div>
I have no experience in webscraping and trying to follow example and the docs to click on the button with text 'Pay Monthly'. This button then dynamically displays some text which I need to copy. How do I go about clicking this for starters, and then reading the text which is displayed. I am trying it with Selenium, would beautifulsoup be better? I have been trying this line of code but it isn't doing anything:
driver.find_element_by_xpath("//a[text()[contains(.,'Pay Monthly')]]").click()
It is always good practice to use mixture of absolute and relative xpath to locate a element.
First thing you should find is a parent that has a unique identifier. The element you mentioned has two parent items with a static id. One is root div and another is ul.
Now either we can follow your path and find the element using Text. Any of the following shall work.
driver.find_element_by_xpath("//div[#id='tabs']//a[text()[contains(.,'Pay Monthly')]]").click()
driver.find_element_by_xpath("//ul[#id='remove']//a[text()[contains(.,'Pay Monthly')]]").click()
But, if the item is static element and considering your goal here, I would suggest the following method. indexing your xpath when it returns multiple elements.
myElement = driver.find_element_by_xpath("//div[#id='tabs']//a[#href='#'][1]")
myElement.click()
And then you can capture the text. You can put some wait to ensure the text gets changed.
myText = myElement.text
Let me know if this doesn't work.
Here is the HTML I'm dealing with
<a class="_54nc" href="#" role="menuitem">
<span>
<span class="_54nh">Other...</span>
</span>
</a>
I can't seem to get my XPath structured correctly to find this element with the link. There are other elements on the page with the same attributes as <a class="_54nc"> so I thought I would start with the child and then go up to the parent.
I've tried a number of variations, but I would think something like this:
crawler.get_element_by_xpath('//span[#class="_54nh"][contains(text(), "Other")]/../..')
None of the things I've tried seem to be working. Any ideas would be much appreciated.
Or, more cleaner is //*[.='Other...']/../.. and with . you are directly pointing to the parent element
In other scenario, if you want to find a tag then use css [role='menuitem'] which is a better option if role attribute is unique
how about trying this
crawler.get_element_by_xpath('//a[#class="_54nc"][./span/span[contains(text(), "other")]]')
Try this:
crawler.get_element_by_xpath('//a[#class='_54nc']//span[.='Other...']');
This will search for the element 'a' with class as "_54nc" and containing exact text/innerHTML "Other...". Furthermore, you can just edit the text "Other..." with other texts to find the respective element(s)
I want to read the amount value (24.40) from this HTML.
<div id="order-total" class="clear-fix" style="margin-bottom:20px;">
<h3 class="col-left">Order total</h3>
<h3 class="col-right" style="display: block;">
<span class="credit-total-to-order" data-total-to-order="24.40">$ 24.40</span>
credits
</h3>
</div>
xpath - /html/body/div/header/section/form/div[5]/h3[2]/span
css - html body.ui-lang-en div#slave-edit.string-v2 header#slave-edit-header.edit
section#order-form form#frm-order-translation div#order-total.clear-fix
h3.col-right span.credit-total-to-order
I know I should use find_element_by_class_name or find_element_by_css_selector.
But not sure what should be the argument.
How can I do it?
Why not select the value from the element and parse the string to get the answer you need. For example, you can split the string and disregard the dollar to return the number you need.
someString = selenium.find_element_by_css_selector(".credit-total-to-order").text
someString.split(' ')[1]
Bear in mind - this will only work for the example you have provided.
Its not necessary to use find_element_by_class_name or find_element_by_css_selector..You can achive it with xpath like this
driver.find_element_by_xpath("//span[#class='credit-total-to-order']").text
UPDATE:
As per your updated html it looks like the style makes your element hidden.Mean while I also came to notice that the value you want to get is also stored in an attribute data-total-to-order.
So you can do somthing like this :
driver.find_element_by_xpath("//span[#class='credit-total-to-order']").get_Attribute("data-total-to-order")
