I’m trying to use the XML::LibXML::Schema to validate a xml file against a xsd.

  • 0

I’m trying to use the XML::LibXML::Schema to validate a xml file against a xsd. The problem is if my xml has multiple semantic issues the validation will die on the first one and not report the others. 




It finds the first error, no reference to <foobar/>
bash-3.2$ ./test.pl test.xsd test.xml 
xmlfile <test.xml> failed validation: test.xml:14: Schemas validity error : Element 'foobar': This element is not expected.



After I remove the first error, it finds another. "ten" is not an unsigned int
xmlfile <test.xml> failed validation: test.xml:11: Schemas validity error : Element 'allocation': 'ten' is not a valid value of the atomic type 'xs:unsignedInt'.



Changing "ten" to 10 fixes this issue
bash-3.2$ ./test.pl test.xsd test.xml 
No issues found

I would like to get a report of ALL the issues on a single run. Any ideas? Should I be using another module for this? Follows my Perl script and my xsd and xml files.

Thanks for your help,

Paulo




xsd:



 <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">

 <!-- channel -->
  <xsd:element name="channel">
   <xsd:complexType>
    <xsd:sequence>

perl script:

    I’ve got contacted by the maintainer of XML::LibXML and filled this is as bug fix. Turns out you can get multiple errors reported by using the command line utility xmllint:

    $ xmllint --schema test.xsd test.xml
<?xml version="1.0" encoding="UTF-8"?>
<request xmlns:xsd="http://www.w3.org/2001/XMLSchema" type="test">
<channel name="channel">
<username>user</username>
<password>pass</password>
</channel>

<hotel id="ten">
<date from="2009-07-07" to="2009-07-17"/>
<room id="1">
<allocation>10</allocation>
</room>
</hotel>
<foobar/>
</request>
test.xml:8: element hotel: Schemas validity error : Element 'hotel', 
attribute 'id': 'ten' is not a valid value of 
the atomic type 'xs:unsignedInt'.
test.xml:14: element foobar: Schemas validity error : Element 'foobar': 
This element is not expected.
test.xml fails to validate
