PHP XML validation

What's the best way to validate an XML file (or part of it) against multiple XSD files?

For example, I have the following schema for a config loader:

<xsd:schema xmlns="http://www.kauriproject.org/schema/configuration"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    targetNamespace="http://www.kauriproject.org/schema/configuration"
    elementFormDefault="qualified">

    <xsd:element name="configuration" type="configuration" />

    <xsd:complexType name="configuration">
        <xsd:choice maxOccurs="unbounded">
            <xsd:element name="import" type="import" minOccurs="0" maxOccurs="unbounded" />
            <xsd:element name="section" type="section" />
        </xsd:choice>
    </xsd:complexType>

    <xsd:complexType name="section">
        <xsd:sequence>
            <xsd:any minOccurs="0" maxOccurs="unbounded" processContents="lax" />
        </xsd:sequence>

        <xsd:attribute name="name" type="xsd:string" use="required" />
        <xsd:attribute name="type" type="xsd:string" use="required" />
    </xsd:complexType>

    <xsd:complexType name="import" mixed="true">
        <xsd:attribute name="resource" type="xsd:string" />
   </xsd:complexType>
</xsd:schema>

Since the configuration class now exists, it allows you to add a tag <section>

defining a specific parser class (much like custom configuration sections in ASP.NET). However, I'm not sure how to check the section being analyzed.

If it is possible to check only this section of code with an XSD file / line without writing it back to the file?

Instead of thinking of it as one big XML file, think of it in terms of chunks. Custom XML Sections are not part of your main file schema, just data. Trying to validate with this XSD file, then when you load the custom section validate this XML file with another XSD file.

I was solving the same problem and I just simply concatenated the files (this was possible in my case as it was very simple).
