In concert with what mzjn said, if you do want to pass a string to etree.parse(), just wrap it in a StringIO object. Example: from lxml import etree from StringIO import StringIO myString = “<html><p>blah blah blah</p></html>” tree = etree.parse(StringIO(myString)) This method is used in the lxml documentation.
from lxml import etree print(etree.tostring(root, pretty_print=True)) you may see more examples here: http://lxml.de/tutorial.html
For me, this issue was not solved until I noticed this little tidbit here: http://lxml.de/FAQ.html#why-doesn-t-the-pretty-print-option-reformat-my-xml-output Short version: Read in the file with this command: >>> parser = etree.XMLParser(remove_blank_text=True) >>> tree = etree.parse(filename, parser) That will “reset” the already existing indentation, allowing the output to generate it’s own indentation correctly. Then pretty_print as normal: >>> tree.write(<output_file_name>, … Read more
You are very close. Use text()= rather than @text (which indicates an attribute). e = root.xpath(‘.//a[text()=”TEXT A”]’) Or, if you know only that the text contains “TEXT A”, e = root.xpath(‘.//a[contains(text(),”TEXT A”)]’) Or, if you know only that text starts with “TEXT A”, e = root.xpath(‘.//a[starts-with(text(),”TEXT A”)]’) See the docs for more on the available … Read more
import lxml.etree as et tree = et.fromstring(”’ … your xml … ”’) for host_ip in tree.xpath(“/scenario/init/send/command[@name=”CER”]/avp[@name=”Host-IP-Address”]”): host_ip.attrib[‘value’] = ‘foo’ print et.tostring(tree)
I bet you’re not using VS 2008 for this 🙂 There’s def find_vcvarsall(version): function (guess what, it looks for vcvarsall.bat) in distutils with the following comment At first it tries to find the productdir of VS 2008 in the registry. If that fails it falls back to the VS90COMNTOOLS env var. If you’re not using … Read more
Below is an example to do what you want. For an HTML document, Cleaner is a better general solution to the problem than using strip_elements, because in cases like this you want to strip out more than just the <script> tag; you also want to get rid of things like onclick=function() attributes on other tags. … Read more
Make sure you have enough memory. Try dmesg | tail to see if it outputs something like: … [3778136.277570] Out of memory: Kill process 21267 (cc1) score 557 or sacrifice child [3778136.277587] Killed process 21267 (cc1) total-vm:365836kB, anon-rss:336228kB, file-rss:0kB
If root.nsmap contains the table namespace prefix then you could: root.xpath(‘.//table:table’, namespaces=root.nsmap) findall(path) accepts {namespace}name syntax instead of namespace:name. Therefore path should be preprocessed using namespace dictionary to the {namespace}name form before passing it to findall().
Thanks to @jessenoller on Twitter I have an answer that fits my needs – you can compile lxml with static dependencies, hence avoiding messing with the libxml2 that ships with OS X. Here’s what worked for me: cd /tmp curl -O http://lxml.de/files/lxml-3.6.0.tgz tar -xzvf lxml-3.6.0.tgz cd lxml-3.6.0 python setup.py build –static-deps –libxml2-version=2.7.3 –libxslt-version=1.1.24 sudo python … Read more
