I'm trying to use XPath to select the items which have a facet with Location values, but currently my attempts even to just select all items fail: The system happily reports that it found 0 items, then returns (instead the nodes should be processed by a foreach loop). I'd appreciate help either making my original query or just getting XPath to work at all.
XML
<?xml version="1.0" encoding="UTF-8" ?>
<Collection Name="My Collection" SchemaVersion="1.0" xmlns="http://schemas.microsoft.com/collection/metadata/2009" xmlns:p="http://schemas.microsoft.com/livelabs/pivot/collection/2009" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<FacetCategories>
<FacetCategory Name="Current Address" Type="Location"/>
<FacetCategory Name="Previous Addresses" Type="Location" />
</FacetCategories>
<Items>
<Item Id="1" Name="John Doe">
<Facets>
<Facet Name="Current Address">
<Location Value="101 America Rd, A Dorm Rm 000, Chapel Hill, NC 27514" />
</Facet>
<Facet Name="Previous Addresses">
<Location Value="123 Anywhere Ln, Darien, CT 06820" />
<Location Value="000 Foobar Rd, Cary, NC 27519" />
</Facet>
</Facets>
</Item>
</Items>
</Collection>
C#
public void countItems(string fileName)
{
XmlDocument document = new XmlDocument();
document.Load(fileName);
XmlNode root = document.DocumentElement;
XmlNodeList xnl = root.SelectNodes("//Item");
Console.WriteLine(String.Format("Found {0} items" , xnl.Count));
}
There's more to the method than this, but since this is all that gets run I'm assuming the problem lies here. Calling root.ChildNodes accurately returns FacetCategories and Items, so I am completely at a loss.
Thanks for your help!
