Hi all,

I have an xml fragment as such:

<meta_tree type="root">
    <meta_data>
        <meta_cat>Content Provider</meta_cat>
        <data>Mammoth</data>
    </meta_data>
    <meta_data>
        <meta_cat>Genre</meta_cat>
        <data>Games</data>
    </meta_data>
    <meta_data>
        <meta_cat>Channel Name</meta_cat>
        <data>Games Trailers</data>
    </meta_data>
    <meta_data>
        <meta_cat>Collection</meta_cat>
        <data>Strategy</data>
    </meta_data>
    <meta_data>
        <meta_cat>Custom 1</meta_cat>
        <data>PC</data>
    </meta_data>
    <meta_data>
        <meta_cat>DRM Protected</meta_cat>
        <data>N</data>
    </meta_data>
    <meta_data>
        <meta_cat>Aspect Ratio</meta_cat>
        <data>16:9</data>
    </meta_data>
    <meta_data>
        <meta_cat>Streaming Type</meta_cat> 
        <data>VOD</data>
    </meta_data>
</meta_tree>

which I garnered from the snippet of $meta_tree->asXML().

So given that, I need to have an xpath query for each element, so I'm using:

$meta_tree->xpath("/meta_data[meta_cat='Content Provider']");

but this returns false.

I have tried:

"/meta_tree/meta_data[meta_cat='Content Provider']"
"//meta_data[meta_cat='Content Provider']"

I've been using AquaPath, which validates my query, so I'm not sure what I'm doing wrong.

Anyone got any ideas?
