            <xs:all>

                <xs:element name="server">

test1.xml

Code: Select all

<root xmlns="test1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  xsi:schemaLocation="test1 test1.xsd">

  <hosts>

    <host id="ABC"/>

    <host id="DEF"/>

  </hosts>

</root>

test2.xml

Code: Select all

<root xmlns:t1="test1" xmlns="test2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

 xsi:schemaLocation="test2 test2.xsd">

 <server host="ABC"/>

</root>

test2.xml raised error like below:

Error: [Xerces] Identity Constraint error: the keyref identity
constraint "Host-FK" refers to a key or unique that is out
of scope.

How can I fix it ? Another words, how import test1.xml instance from test2.xml ?
