ImportError: No module named lxml.etree

问题 I'm trying to import premailer in my project, but it keeps failing at the etree import. I installed the 2.7 binary for lxml. The lxml module imports fine, and it's showing the correct path to the library folder if I log the lxml module, but I can't import etree from it. There's an etree.pyd in the lxml folder but python can't seem to see\read it. I'm on windows7 64bit. Does anyone know what's going wrong here? 回答1: Try adding the library to the GAE .yaml file. Under libraries add -name: lxml

lxml classic: Get text content except for that of nested tags?

问题 This must be an absolute classic, but I can't find the answer here. I'm parsing the following tag with lxml cssselect: <li><a href="/stations/1"><span class="num">3</span> Detroit</a></li> I want to get the content of the <li> tag without the content of the <span> tag. Currently I have: stop_list = doc.cssselect('ol#stations li a') start = stop_list[0].text_content().strip() But that gives me 3 Detroit . How can I just get Detroit ? 回答1: itertext method of an element returns an iterator of

Automatic XSD validation

由 心不动则不痛 提交于 2019-12-19 06:01:42
问题 According to the lxml documentation "The DTD is retrieved automatically based on the DOCTYPE of the parsed document. All you have to do is use a parser that has DTD validation enabled." http://lxml.de/validation.html#validation-at-parse-time However, if you want to validate against an XML schema, you need to explicitly reference one. I am wondering why this is and would like to know if there is a library or function that can do this. Or even an explanation of how to make this happen myself.

Parsing Source Code (Python) Approach: Beautiful Soup, lxml, html5lib difference?

由 蓝咒 提交于 2019-12-18 18:26:30
问题 I have a large HTML source code I would like to parse (~200,000) lines, and I'm fairly certain there is some poor formatting throughout. I've been researching some parsers, and it seems Beautiful Soup, lxml, html5lib are the most popular. From reading this website, it seems lxml is the most commonly used and fastest, while Beautiful Soup is slower but accounts for more errors and variation. I'm a little confused on the Beautiful Soup documentation, http://www.crummy.com/software/BeautifulSoup

How to install lxml in Python 3.4 on Windows machine

由 我的未来我决定 提交于 2019-12-18 18:04:10
问题 I've been spending hours on this. I'm new to Python and can't see what the solution may be. I have Python 3.4 and want to work with .docx , which requires lxml . The workflow I've done so far is: I go to the Python lxml package installer page, but it's quite confusing to know which version I need. I tried with several of them that contained the 34 numbers, both .exe and .tar . I also tried pip install lxml3.4.4 and pip install lxml 3.4.4 . None of them worked either. This is what the command
