XML Module v1.2

The XML Module can process and extract data from an XML document. Although DataWeave is recommended
for most XML-related use cases, the XML module should be used for cases that involve the use of XML
standards such as XSLT, XPath and XQuery, or XSD.

To use the XML module, you can add it to your Mule app through the Studio UI, or you can add the
following dependency in your `pom.xml` file:

```xml
<dependency>
    <groupId>org.mule.modules</groupId>
    <artifactId>mule-xml-module</artifactId>
    <version>x.x.x</version> <!-- or newer -->
    <classifier>mule-plugin</classifier>
</dependency>
```

Mule runtime engine (Mule) converts RELEASE to the latest version.

## Validate Against a Schema

When using the XML Module to validate against a schema that has references to other local schema
files, validation can fail because the access was restricted by the `expandEntities` as it was using
the default value of NEVER. The error message is: The supplied schemas were not valid.
schema\_reference: Failed to read schema document `NMVS_Composite_Types.xsd`, because `file` access
is not allowed due to restriction set by the accessExternalSchema property.

You can eliminate this issue by adding `expandEntities="INTERNAL"` to the `xml-module:config`
element.
