lxml

问题 I'm trying to use lxml to process a file that may have some non-xml junk both before and after the XML content, imagine someone captured a terminal buffer and I have something like this: user@host: cat /tmp/log.xml <log> <foo>...</foo> <bar>.. ... </bar> </log> user@host: If I hand etree.parse the filename, it chokes on the beginning content. I can delete the first set of lines until I find a line starting with '<' and hand that to etree.parse, but then it chokes on the closing content. The

问题 I need to automatically scan lots of html documents for ad banners that are surrounded by an anchor tag, e.g.: <a href="http://ad_network.com/abc.html"> <img src="ad_banner.jpg"> </a> As a newbie with xpath, I can select such anchors via lxml like so: text = ''' <a href="http://ad_network.com/abc.html"> <img src="ad_banner.jpg"> </a>''' root = lxml.html.fromstring(text) print root.xpath('//a[contains(@href,("ad_network.")) or contains(@href,("other_ad_network."))][descendant::img]') In the

问题 I'm trying lxml requests on Replit and I don't understand why it isn't working.

问题 I have a Python 2.7.6 Flask application that is trying to parse a SAML XML document using the lxml library. I'm running into an issue where etree.tostring(...) returns an empty string. etree_string = etree.tostring(etree.fromstring(b'<test1><test2></test2></test1>')) return etree_string # output: '' This appears to only occur when the code is run within the Flask app, served by mod_wsgi in Apache. I say this because in the same virtualenv, if I open a python interpreter and run: >>> etree

问题 I'm having the following error when trying to run "pip install lxml" into a virtualenv in Ubuntu 12.10 x64. I have Python 2.7. I have seen other related questions here about the same problem and tried installing python-dev, libxml2-dev and libxslt1-dev.

问题 I'm tring to wrap the contents of a tag with BeautifulSoup. This: <div class="footnotes"> <p>Footnote 1</p> <p>Footnote 2</p> </div> should become this: <div class="footnotes"> <ol> <p>Footnote 1</p> <p>Footnote 2</p> </ol> </div> So I use the following code: footnotes = soup.findAll("div", { "class" : "footnotes" }) footnotes_contents = '' new_ol = soup.new_tag("ol") for content in footnotes[0].children: new_tag = soup.new_tag(content) new_ol.append(new_tag) footnotes[0].clear() footnotes[0]

问题 This question already has answers here : How do you install lxml on OS X Leopard without using MacPorts or Fink? (15 answers) Closed 6 years ago . I've installed gcc on Mac OS X 10.6.8 using the osx-gcc-installer. Downloading XCode would take forever, but I managed to download and install this 170-Mb package, and I am able to compile a Hello, world! program using iostream and std::cout . Then I tried to install lxml using python's easy_install lxml . It couldn't find gcc-4.0 . I added a

问题 I'm working in Python with HTML that looks like this. I'm parsing with lxml, but could equally happily use pyquery: <p><span class="Title">Name</span>Dave Davies</p> <p><span class="Title">Address</span>123 Greyfriars Road, London</p> Pulling out 'Name' and 'Address' is dead easy, whatever library I use, but how do I get the remainder of the text - i.e. 'Dave Davies'? 回答1: Each Element can have a text and a tail attribute (in the link, search for the word "tail"): import lxml.etree content=''
