LXML and XSL document() Function

Question

Hi i got the following files :

merge.py:

from lxml import etree

xml_input = etree.XML(open(\'a.xml\', \'r\').read())
xslt_root = etree.XML(open(\'me         


        

Answer 1

You need to register a URI resolver. See the documentation.

Probably something like this (untested):

class FileResolver(etree.Resolver):
    def resolve(self, url, pubid, context):
        return self.resolve_filename(url, context)

parser = etree.XMLParser()
parser.resolvers.add(FileResolver())
xml_input = etree.parse(open('a.xml','r'), parser)
xslt_root = etree.parse(open('merge.xsl','r'), parser)
transform = etree.XSLT(xslt_root)
print str(transform(xml_input))

Answer 2

Why not simply do this?

from lxml import etree

xml_input = etree.parse("a.xml")
xslt_root = etree.parse("merge.xsl")
transform = etree.XSLT(xslt_root)
print str(transform(xml_input))

More straightforward, no need for a resolver.
