I am looking to write a custom .NET class to provide a mechanism of returnin
g
the number of characters in an XML element.

I have created a simple method named Length(), with one parameter 'sString'
of type string. However, when I attempt to use an element in my XML document
I receive the following error:

"The definition <XPath to element name> is not compatible with the argument
type (String)"

However If I pass an attribute to the method everything works as expected.
Can anyone advise what parameter type I should be using in my method? Note:
The element in question has a base datatype of 'xs:string', Content Type of
'SimpleContent' and a Derived By value of 'Extension'.

An example of my XML document structure is below.

Regards, Nick


Example:
<order>
<orderLines>
<line>
<ProductCode error="This is some error text">HL1450</ProductCode>
</line>
</orderLines>
</order>

/order/orderLines/line/ProductCode <-- Will not work as an input to the meth
od
/order/orderLines/line/ProductCode/@error <-- Will work as an input to the
method

Try TypedXmlDocument, this should allow you to get at the node pretty easily
and work with it in the DOM to get the inner text of the node.
