Hi Giovanni,

Not really an answer to your question but just an idea which maybe can be helpful, also depending on your scenario.

Extracts from what Giovanni Torres wrote:

Some of you might not be happy with my question. But, I'm dealing with an XML file that has line breaks in XML attributes. I use lxml to parse the file, run some XPath queries, make changes to it and write it back. Unfortunately, lxml removes the line breaks from the attributes.

Maybe you could use entities which are preserved in the attributes.

If the input xml is not too big you could replace the \n with e.g. 
 and then back.

xml='<example attr="This is an attribute with several&#10;break&#10;lines"/>'
...
do lxml processing
...
output = etree.tostring (processed)
output.replace ('&#10;','\n')


Lorenzo.

Here is what I mean more clearly: $ cat example.xml <example attr="This is an attribute with several break lines"/> $ cat test.py import sys import lxml.etree xml = lxml.etree.parse(sys.stdin) xml.write(sys.stdout) print() $ python test.py < example.xml <example attr="This is an attribute with several break lines"/>() $ python -c 'import lxml.etree ; print(lxml.etree.__version__)' 2.3.0 $ python -V Python 2.6.5 $ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 10.04.2 LTS Release: 10.04 Codename: lucid $ Is there any way I can get lxml to write those line breaks back? I'm actually not sure if they are even legal. But, they seem to be according to this: http://stackoverflow.com/questions/449627/are-line-breaks-in-xml-attribute-values-valid Thanks in advance for your help! -- Giovanni
