How to find text in specific nested tag wih lxml and pyhthon?
Here's my attempt. It gives your desired output for your sample input. I made it tolerant of certain tag changes like div vs. span. import xml.etree.cElementTree as etree # or: from lxml import etree body = etree.parse('test.html').find('body') for aname in body.iterfind('*[@class="aname"]'): cname = aname.find('*[@class="bname"]//a[@class="cname"]') print cname.text # title print cname.get('href')...
Python: Scrape Data from Web after Inputing Info
python,web-scraping,html-parsing,lxml,lxml.html
The main issue was that you needed to make a GET request, not a POST. Plus, @Paul Lo is right about the date ranges. For the sake of example, I'm querying from 2010 to 2015. Also, you have to pass query parameters as strings. 00 evaluated to 0, requests converted...
How can I strip namespaces out of an lxml tree?

One possible way to remove namespace prefix from each element : def strip_ns_prefix(tree): #iterate through only element nodes (skip comment node, text node, etc) : for element in tree.xpath('descendant-or-self::*'): #if element has prefix... if element.prefix: #replace element name with it's local name element.tag = etree.QName(element).localname return tree Another version which...
How do I do thread-safe python XML validation?
python,xml,multithreading,validation,lxml
On linux, a forked process gets a copy-on-write view of the parent's memory. You can leverage this to process a large object with little overhead and without changing the object in the parent's memory space. After creating the object, create pipes for communication and fork a child to do the...
Namespace argument in lxml parsing
You need to use the namespace prefix while querying. like node.xpath('//html:body', namespaces={'html': 'http://...'}) or you can use the .nsmap node.xpath('//html:body', namespaces=node.nsmap) This assumes all the namespaces are defined on tag pointed by node. This is usually true for most xml documents....
Pandas read_html equivalent for a lxml table

Difference between a/img/..//text() and a//text()
The difference between a/img/..//text() and a//text() is that the first will return you text nodes ONLY from a elements with img elements as children, whereas the second will return text nodes from a elements irrespective of whether they have img elements as children. Put another way, a/img/..//text() could equally be...

Installing lxml on RHEL for Python 2.7
The short answer is, not easily. I'm assuming you're using RHEL5 since you mentioned python 2.4 was in the repo. The problem is that lxml is not a pure python library, it is a rather thin wrapper around two C/C++ libraries, libxml2 and libxslt. This means that any RPM installer...

How to extract efficientely content from an xml with python?
python,xml,python-2.7,pandas,lxml
There are several things wrong here. (Asking questions on selecting a library is against the rules here, so I'm ignoring that part of the question). You need to pass in a file handle, not a file name. That is: y = BeautifulSoup(open(x)) You need to tell BeautifulSoup that it's dealing...

XSLT template does not apply to all elements using lxml
That really seems odd - unless you realize what happens. This has nothing to do with how lxml performs XSLT tranformations, as far as I can see.
