[Exist-open] XPointer and ranges?

[Ben Y. <by...@bj...>]

I'm working with a file that has a structure similar to a poem.

<poem>
    <stanza id="1">
        <line id="1.1">text</line>
        <line id="1.2">text</line>
        <line id="1.3">text</line>
        <line id="1.4">text</line>
        <line id="1.5">text</line>
    </stanza>
    <stanza id="2">
        <line id="2.1">text</line>
        <line id="2.2">text</line>
        <line id="2.3">text</line>
    </stanza>
</poem>

Currently I'm having trouble retrieving a range of nodes (e.g., from
line[@id='1.4'] to line[@id='2.2'].

Is there a way to do this in eXist? I've read that XPointer has similar
capabilities.

Thanks,
Ben
