为什么我的XML模式无法提取错误？

Question

My schema wont pick up the errors in my data, is there a glaring reason? Please see below, essentially for the restrictions I created it should come up with errors when other information has been given, but that is not the case with mine. It just appears valid. Here I applied a restriction using type string and ennumerating it. It should throw validation errors because the spelling is incorrect in some places.

Answer 1

Trying to validate your sample XML with the XSD, it threw some errors, so I couldn't reproduce your problem, but only fix the errors of your XSD. I used the command

xmlstarlet val --err --xsd source.xsd input.xml

to validate your XSD. XSD-1.0 seemed to suffice to validate it, so no XSD-1.1 processor was necessary.

---

One of the problems of your source XML seemed to be the leading and trailing spaces of the value of ResidenceStatus .

Applying your XSD to the XML lead to errors until I fixed the definition of ResidenceStatus . So far, I cannot tell if this occurs due to your XSD processor.

But you can try to fix the definition to

<xs:element name="ResidenceStatus">
  <xs:simpleType>
    <xs:restriction base="normalized">
        <xs:enumeration value="In-state"/>
        <xs:enumeration value="Out-of-state"/>
    </xs:restriction>
  </xs:simpleType>
</xs:element>

and add the type definition of normalized at the end of the root level of your xs:schema :

<xs:simpleType name="normalized">
  <xs:restriction base="xs:string">
    <xs:whiteSpace value="collapse"/>
  </xs:restriction>
</xs:simpleType>

This simpleType named normalized will remove leading and trailing spaces of the element's value, so that the enumeration will match.

PS: your XSD had a typo:
<xs:simpletype> of ResidenceStatus should have been <xs:simpleType> .
