111,Genshi strips XML namespace declaration,Alec Thomas <alec@…>,cmlenz,"Given the input:

{{{
#!xml
<?xml version=""1.0"" encoding=""utf-8""?>
<root />
}}}

Genshi currently produces:

{{{
#!xml
<root />
}}}

This is because the XML namespace is distinct from processing instructions, thus Expat has a distinct callback for it. This callback is not currently handled by Genshi.

Patch attached which adds an XML_DECL type, which effectively just contains the values passed through from Expat. eg.

{{{
XML_DECL (u'1.0', u'utf-8', 1) ('feed.xml', 1, 0)
}}}

Outputs as:

{{{
#!xml
<?xml version=""1.0"" encoding=""utf-8"" standalone=""yes""?>
}}}

I didn't add XPath support for it, as apparently [http://www.w3.org/TR/xpath#section-Processing-Instruction-Nodes it's not a valid node] (this is the only reference that I could find in the spec').

(Note that Expat doesn't appear to generate text elements between the XML decl and the first element, so the unit tests explicitly use \n)",defect,closed,major,0.4.1,Parsing,0.3.6,fixed,,
