[lxml-dev] Text attribute is None when element has text
If I run the code: test = etree.XML('<root><a/>text</root>') for x in test.iter(): print("%s - %s"%(x.tag, x.text)) I get the output: root - None a - None I expected that root.text would have been 'text' rather than none. However, if I flip the text and <a/> tag, then it works. E.g. test = etree.XML('<root>text<a/></root>') for x in test.iter(): print("%s - %s"%(x.tag, x.text)) Output: root - text a - None Anyone know why this is, or how to work around it? Thanks! - Clif

Sure, read the docs: http://codespeak.net/lxml/tutorial.html#elements-contain-text Stefan

Take a look at the tutorial, especially the "Elements contain text" section near here: http://codespeak.net/lxml/tutorial.html#the-element-class Hopefully that will explain how .text and .tail work for accessing text. The short answer is that your text is in test.find( 'a' ).tail, though. The itertext method may also be useful for you, depending on your use case. -- John Krukoff <jkrukoff@ltgc.com> Land Title Guarantee Company

I have attempted to explain this here: http://www.nmt.edu/tcc/help/pubs/pylxml/ The relevant section is here: http://www.nmt.edu/tcc/help/pubs/pylxml/etree-view.html Here's your interactive example with the .tail attribute shown. ================================================================ Python 2.5.1 (r251:54863, Jun 15 2008, 18:24:51) [GCC 4.3.0 20080428 (Red Hat 4.3.0-8)] on linux2 Type "help", "copyright", "credits" or "license" for more information.
from lxml import etree as et test=et.XML('<root><a/>text</root>') for x in test.iter(): ... print ( "tag='%s' text='%s' tail='%s'" % ... (x.tag, x.text, x.tail) ) ... tag='root' text='None' tail='None' tag='a' text='None' tail='text'
