Hi All -

I've run into a problem trying to parse a xml stream.

I've consumed a web service that returns the following string:

<?xml version="1.0" encoding="utf-8"?>
<!-- Elevation Values of -1.79769313486231E+308 (Negative Exponential Value) may mean the data source does not have values at that point. --> <USGS_Elevation_Web_Service_Query>
<Elevation_Query x="-104.8913446" y="39.93402002"> <Data_Source>NED Contiguous U. S. 1/3W arc second elevation data</Data_Source>
<Data_ID>NED.CONUS_NED_13W</Data_ID> <Elevation>5081.4971523335</Elevation>
<Units>FEET</Units>
</Elevation_Query>

I've worked through some different test xml files and successsfully selected (using xpath query) the nodes' inner text using the code below:

XmlDocument doc = new XmlDocument();
document.Load(<path to test xml doc>);
string xpath = ("Customers/Customer[@id='5']/LastName");
XmlNode node = document.SelectSingleNode(xpath);

My questions:
1. why is this technique not working on the string returned by the web service? I gather the xml string is poorly formed (the tag "<USGS_Elevation_Web_Service_Query>" is not closed).

2. Any suggestions on a workaround or something I'm missing? perhaps Xpath syntax problem?

Thanks -

Matt
