Hello,

I have some XML loaded into an XmlDocument and
attempting to figure out how to access certain nodes. I
assume I should use XPath, but I am having trouble
getting the XPath syntax correct. Where might I be going
wrong? Any help would be appreciated!

XML:

<Reason>

<ReasonCategory>Death</ReasonCategory>
<Contacts>
<Contact>
<Name></Name>
<Phone></Phone>

<Address></Address>

<CityStateZip></CityStateZip>

<Relation></Relation>

<IsMember></IsMember>
</Contact>
</Contacts>
<ReasonDetails>

<PlaceOfDeath></PlaceOfDeath>

<CauseOfDeath></CauseOfDeath>

<FuneralLocationName></FuneralLocationName>

<FuneralDateTime></FuneralDateTime>

<ReasonDetails>
<RequestedServices>
<RequestedService>

<OfferedServiceName></OfferedServiceName>

<AssignedTo></AssignedTo>
</RequestedService>
</RequestedServices>
<FormDetails>

<CompletedBy></CompletedBy>

<CompletedDate></CompletedDate>
<Notes></Notes>
</FormDetails>
</Reason>

I am attempting to access the ReasonCategory node with:

XmlNodeReader myXmlNodeReader = new XmlNodeReader
(myXmlDocument.SelectSingleNode("Reason/ReasonCategory"));
string ReasonCategory =
myXmlNodeReader.Value;

But the XmlNodeReader isn't finding the node. Thanks for
your help!
 
Nevermind, I figured it out. Sorry!

XML:

<Reason>

<ReasonCategory>Death</ReasonCategory> etc.
</Reason>

The "Value" of an XmlElement node is null. What you want is the InnerText.
And instead of using XmlNodeReader you can also use the SelectSingleNode
result directly, e.g.

string ReasonCategory =
myXmlDocument.SelectSingleNode("/Reason/ReasonCategory").InnerText;
