Re: Python script to optimize XML text
Hey guys, Thanks for everyone's input. I wanted to learn regular expressions, however I'm finding them to be quite evil. I think I've learned that it's always a good idea to make regex a very LAST resort. This is my opinion I'm developing on. In any case, I like the ideas mentioned here concerning using the XML parser to do the job for me. Thanks again everyone, I think I'll be going with the XML parser to do what I need. Have a good day everyone.

So you get by yourself to the truth of this famous quote: Some people, when confronted with a problem, think “I know, I'll use regular expressions.” Now they have two problems.

Python script to optimize XML text
Hi, I'm currently seeking a python script that provides a way of optimizing out useless characters in an XML document to provide the optimal size for the file. For example, assume the following XML script: root Test/Test !-- CommentedOutElement/ -- !-- Do Something Else -- /root By running this through an XML optimizer, the file would appear as: rootTest//root Note that the following were changed: - All comments were stripped from the XML - All spaces, tabs, carriage returns, and other forms of unimportant whitespace are removed - Elements that contain no text or children that are in the form of Empty/Empty use the short-hand method for ending an element body: Empty/ Anyone know of a tool or python script that can perform optimizations like explained above? I realize I could probably do this with regular expressions in python, however I was hoping someone already did this work. -- http://mail.python.org/mailman/listinfo/python-list
Re: [lxml-dev] Python script to optimize XML text
If your XML is well-formed, a XSLT is probably your best choice. I believe even the most trivial 'pass through' example might produce the output you expect here. -- Sidnei da Silva Enfold Systemshttp://enfoldsystems.com Fax +1 832 201 8856 Office +1 713 942 2377 Ext 214 -- http://mail.python.org/mailman/listinfo/python-list
