Reference XML to another XML, possible?

1

is it possible to make an XML file reference another XML file?
Like I have an XML like so:

 <press>
    <path="pages/">

    <pages>
        <id="0"/>
        <pagename="test"/>
        <thumb="thumb.jpg"/>
        <content>
            //refer to content.xml
        </content>
    </pages>

    <pages>
        <id="1"/>
        <pagename="test2"/>
        <thumb="thumb.jpg"/>
        <content>
            //refer to another content.xml
        </content>
    </pages>
</press>

content.xml
i’ll have multiple instances of this, seperated by folders.


<content>
    <name="TEST">
    <title>
            This is a test.
    </title>
    <desc>
        Lorem ipsum and stuff.
    </desc>
</content>

i hope that was clear… is that possible? if so, how would I do that?
or if that can’t be done, any alternative method?
