Question

我已经包含了用于产生错误的文件。

这些工作在oXygen; python lxml脚本不起作用。

更具体地说，转换有效，但验证错误无法正常工作。（例如，如果id更改为ids。）

toytest.sch

<schema xmlns="http://purl.oclc.org/dsdl/schematron" >

    </rule>
    </pattern>
    </schema>

但是，当我尝试使用python lxml时，我得到一个RELAXNG_ERR_ELEMNAME。这是python script：

 import shlex, subprocess
 from lxml import isoschematron
 from lxml import etree

# _VALIDATE_
# parse sch,xml,relaxNG
parser_xml = etree.XMLParser()
sch_doc = etree.parse('toy.sch')
schematron =  isoschematron.Schematron(sch_doc, store_report = True)

#xml_doc = etree.parse('toy.xsl', parser_xml)
xml_doc = etree.parse('toy.xsl')

##compact to relaxNG
#pytrang randng.rnc randng.rng 
randNG_doc = etree.parse('randng.rng')
relaxng = etree.RelaxNG(randNG_doc)

# validate against schematron
validationResult = schematron.validate(xml_doc)
print '--------------------'
print validationResult

# validate against relaxNG
try:
    validateRelaxng =  relaxng.assert_(xml_doc)
print 'relaxNG worked'
except AssertionError as e:
error =   relaxng.error_log.last_error
print relaxng.error_log
print error.type_name
if error.type_name == 'RELAXNG_ERR_ATTRVALID':
    print 'invalid attribute'
 #       RELAXNG_ERR_ELEMNAME

 # _TRANSFORM_ 
 #just run it from shell
 cmd = "java -cp /usr/share /java/saxonb.jar  net.sf.saxon.Transform -xsl:test2.xsl -s:toy.xml -o:toy6.html"
 args = shlex.split(cmd)
 #subprocess.Popen(args)

转换有效，验证不会产生正确的错误。

我最后只是使用命令行调用进行转换。 sch和rng文件xslt_1.0是否兼容？为什么我不能让简单的脚本工作，还有什么其他问题呢？

最好的

Answer 1

无意中尝试解析样式表......应该从元素错误中找出答案。相反，应该只解析xml doc，然后对其进行验证。

xslt验证/转换在oXygen中工作，但不能与lxml python脚本一起工作？
