您好我有以下文件:
merge.py:
from lxml import etree
xml_input = etree.XML(open('a.xml', 'r').read())
xslt_root = etree.XML(open('merge.xsl', 'r').read())
transform = etree.XSLT(xslt_root)
print str(transform(xml_input))
merge.xsl:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<merge>
<xsl:copy-of select="."/>
<xsl:copy-of select="document('b.xml')"/>
</merge>
</xsl:template>
A.XML:
<?xml version="1.0" encoding="ISO-8859-1"?>
<a>
<test id="1"/>
</a>
b.xml:
<?xml version="1.0" encoding="ISO-8859-1"?>
<b>
<test id="2"/>
</b>
4个文件在同一个目录中,当我调用merge.py时出现错误:
lxml.etree.XSLTApplyError: Cannot resolve URI string://__STRING__XSLT__/b.xml
有什么想法吗?我做错了什么?

您需要注册URI解析器。请参阅the documentation。
可能是这样的(未经测试):
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))
答案 1 :(得分:6)
为什么不简单地这样做?
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))
更直接,不需要解析器。
