Remove whitespaces and line breaks in a XML file

[David Vicente]

Hi,



I?m parsing an xml file with xml.etree. It works correctly, but I have a
problem with the text attribute of the elements which should be empty. For
example, in this case:

<book>

<author>Ken<author>

</book>



The text element of ?book? should be empty, but it returns me some
whitespaces and break lines. I can?t get remove these whitespaces without
remove information.



Some idea?

Only a DTD (or schema) can provide the information which whitespace in an
XML document is meaningful and which isn't, so there is no generic way to
"do it right", especially not for something as generic as an XML parser.

What may work for you is to check if an Element has children and only
whitespace as text ("not el.text or not el.text.strip()"), and only then
replace it by None.

I found the code posted at

http://infix.se/2007/02/06/gentlemen-indent-your-xml

quite helpful in turning my xml into human-readable structures. It works
best for XML-Data.

I?ll try to mix it with my code (xml.etree).
Thanks ;)

It's done in one line with

lxml, which the code is using, already has a pretty_print feature
according to this http://codespeak.net/lxml/tutorial.html which would
do the same, would it not?
