So I have the following XML structure.

Code:
 <xrs:Package>
    <xrs:Item>
        <xrs:Fields>
            <xrs:CustomFields>
                <xrs:CustomField name="SPV" value="asdkjadiao"/>
                <xrs:CustomField name="SPR" value="mooseral"/>
(With appropriate closing tags)
I'm supposed to be using an XPath to reach the value of SPV.

I've got the following:
/xrs:Item/xrs:Fields/xrs:CustomFields/xrs:CustomField@value[@name="SPV"]

but it's not finding the value.
Any ideas where i've gone wrong?
