JAXB绑定文件中的XPath评估导致目标节点为空

Question

I try to change xsd element name via external jaxb binding file but for some reason global binding does not work and Xpath can't find the element

Schema I want to change:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema elementFormDefault="qualified" targetNamespace="http://schemas.sitels.ru/FORIS/IL/DomainModel" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://schemas.sitels.ru/FORIS/IL/DomainModel">
  <xs:complexType name="BaseDictionary">
    <xs:sequence>
      <xs:element minOccurs="0" name="Code" nillable="true" type="xs:string"/>
      <xs:element minOccurs="0" name="DateFrom" nillable="true" type="xs:dateTime"/>
      <xs:element minOccurs="0" name="DateTo" nillable="true" type="xs:dateTime"/>
      <xs:element minOccurs="0" name="Id" nillable="true" type="tns:UniqueIdentifier"/>
      <xs:element minOccurs="0" name="Name" nillable="true" type="xs:string"/>
    </xs:sequence>
  </xs:complexType>
  <xs:element name="BaseDictionary" nillable="true" type="tns:BaseDictionary"/>
  <xs:complexType name="UniqueIdentifier">
    <xs:sequence>
      <xs:element minOccurs="0" name="EntityId" type="xs:long"/>
      <xs:element minOccurs="0" name="ForisId" type="xs:int"/>
    </xs:sequence>
  </xs:complexType>
  <xs:element name="UniqueIdentifier" nillable="true" type="tns:UniqueIdentifier"/>
</xs:schema>

Jaxb binding file:

<?xml version="1.0" encoding="UTF-8"?>
<jaxb:bindings xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
               xmlns:xs="http://www.w3.org/2000/10/XMLSchema-instance"
               xs:schemaLocation="http://java.sun.com/xml/ns/jaxb http://java.sun.com/xml/ns/jaxb/bindingschema_2_0.xsd"
               jaxb:version="2.1">

    <jaxb:bindings schemaLocation="DomainModel.xsd" node="//xs:schema//xs:element[@name='BaseDictionary']">
        <jaxb:class name="DomainBaseDictionary" />
    </jaxb:bindings>
</jaxb:bindings>

I get XPath evaluation of "//xs:schema//xs:element[@name='BaseDictionary']" results in empty target node when trying to compile

The xs: namespace prefix referes to different namespaces in the two documents. In your xsd you have:

xmlns:xs="http://www.w3.org/2001/XMLSchema"

In your binding file you have:

xmlns:xs="http://www.w3.org/2000/10/XMLSchema-instance"

So xs:schema != xs:schema. Either fix the namespaces, or write the xpath namespace neutral ( //*[local-name() = 'schema']/*[local-name()='element' and @name='BaseDirectory'] )
