How to use xpath or lxml to get a specific xsd element data(namespace includes)?-CodePudding

I am having a problem to reach vc:minVersion from xsd file.

Part of xsd:

<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="lbs"
    elementFormDefault="qualified"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:vc="http://www.w3.org/2007/XMLSchema-versioning"
    rb:version="0.2"
    vc:minVersion="1.1"
>

  <!-- main -->
  <xs:element name="lbs">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="header">

My code:

import lxml.etree as ET
dom = ET.parse(u'/lbs.xsd')
rootxml = dom.getroot()
nss = rootxml.nsmap
for subtag in rootxml.xpath(u'//minVersion', namespaces=nss):
    #do something
    print(subtag)

Code shows nothing, when I expect to get "1.1" as answer. Please help :)

CodePudding user response：

If namespaces are used it should be

//@vc:minVersion

Ignoring namespaces it would be

//@*[local-name()="minVersion"]
