Why the character apostrophe is not escaped?
I was wondering why the apostrophe is not automatically escaped as other characters? For example: < is transformed to *<* and
is transformed to *>* but ' is not transformed to *'*
Python : sys.version_info(major=2, minor=7, micro=6, releaselevel='final', serial=0) lxml.etree : (3, 3, 3, 0) libxml used : (2, 9, 1) libxml compiled : (2, 9, 1) libxslt used : (1, 1, 28) libxslt compiled : (1, 1, 28)
Hi,
I was wondering why the apostrophe is not automatically escaped as other characters?
Because it doesn't have to? http://www.w3.org/TR/2008/REC-xml-20081126/#syntax
For example:
< is transformed to <
"<" and "&" must be escaped
and
is transformed to >
">" may be escaped (and must be in certain contexts)
but ' is not transformed to '
"'" (and '"') may be escaped) So maybe this is libxml2's decision of how to handle things, when there's a choice. Holger Landesbank Baden-Wuerttemberg Anstalt des oeffentlichen Rechts Hauptsitze: Stuttgart, Karlsruhe, Mannheim, Mainz HRA 12704 Amtsgericht Stuttgart

Because it's not needed? See https://wiki.python.org/moin/EscapingXml for a similar discussion.

How can I escape it if I need to do it? My solution at this moment is to use tostring() to save the file and after that apply a replace, nevertheless, I think is a bad and dirty solution, because I need to add the XML's header <?xml version='1.0' encoding='UTF-8'?> with hardcoding.

Do you need it because the data is parsed by a non-compliant XML parser, or do you need it because the data is then embedded in another context (like a SQL sentence)?
