Java – how do I validate my XML by referencing XSD from classpath?

As part of my XML transformation (using XSL), I am creating an attribute for the schema location so that the result of the transformation can be verified However, when I try to run it as a stand-alone test, I want to be able to set the corresponding property / value of the mode location to close my classpath

After a Google search, I tried various schemalocation attributes. The latest attempt is:

..
<xsl:attribute name="xsi:external-noNamespaceSchemaLocation">
  <xsl:value-of select="$schemaLocation"/>
</xsl:attribute>
..

The results after transformation are as follows:

<?xml version="1.0" encoding="UTF-8"?>
<emrException 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:external-noNamespaceSchemaLocation="emrException_1_0.xsd">
    ..
    <!-- more well-formed XML -->
</emrException>

I have carefully checked my emrexception when the validator runs_ 1_ The 0.xsd file is obviously located in classpath It is a DOM validator. I use Xerces 2.9 1 / Xalan 2.7. 1. My result is:

Caused by: org.xml.sax.SAXParseException: 
    cvc-elt.1: Cannot find the declaration of element 'emrException'.

However, when I exchange schema locations that read XSD files from the file system or external URLs, the validator runs interesting

How do I read XSD from classpath?

Solution

One method is to implement its own lsresourceresolver and lsinput, so that the incoming systemid can be resolved
