xpath fails : "Parameter" have special meaning ?

[John A Grandy]

Is there something special in XML about the name "Parameter" ... I am not
able to XPATH query for nodes named "Parameter"

<Root>
<Category CategoryID="1">
<Elements>
<Element ElementID="1"></Element>
<Element ElementID="2"></Element>
<Element ElementID="3"></Element>
</Elements>
<Parameters>
<Parameter ParameterID="1" ></Parameter>
<Parameter ParameterID="2" ></Parameter>
<Parameter ParameterID="3" ></Parameter>
</Parameters>
</Category>
<Category CategoryID="2">
</Category>
</Root>
XMLDocument xmldoc = New XMLDocument;
xmldoc.Load("<p ath to above file>");
string xpath = "/Root/Category[@CategoryID='1']/Elements/Element";
XMLNodeset nodes = xmldoc.SelectNo des(xpath);
//nodes.Count = 3

xpath = "/Root/Category[@CategoryID='1']/Parameters/Parameter";
nodes = xmldoc.SelectNo des(xpath);
//nodes.Count = 0

Hello!

XMLDocument xmldoc = New XMLDocument;
xmldoc.Load("<p ath to above file>");
string xpath = "/Root/Category[@CategoryID='1']/Elements/Element";
XMLNodeset nodes = xmldoc.SelectNo des(xpath);
//nodes.Count = 3

xpath = "/Root/Category[@CategoryID='1']/Parameters/Parameter";
nodes = xmldoc.SelectNo des(xpath);
//nodes.Count = 0

Is this really your code? Maybe you have a typo in the original?

Does this work:
XmlElement params =
xmldoc.SelectSi ngleNode("/Root/Category[@CategoryID='1']/Parameters") as
XmlElement;
params.SelectNo des("Parameter" ).Count...

The following vbscript can get correct result, maybe you need to double
check your code.

Set xmlDoc = CreateObject("M sxml2.DOMDocume nt.4.0")
xmlDoc.async = false
xml_path = "onega.xml"
xmlDoc.load xml_path
xmlDoc.setPrope rty "SelectionLangu age", "XPath"
xpath_str = "/Root/Category[@CategoryID='1']/Parameters/Parameter"
set objNodeList = xmlDoc.document Element.selectN odes(xpath_str)
WScript.Echo CStr(objNodeLis t.length)
