Hi,everyone! Now I have a XML file and it looked like below:

<Nozzle-Flange-Weight>
<Standard value="HG/T">
<Flange-type type="PL">
<PN PN="2.5">
<Weight DN="10">0.5</Weight>
<...other weight...>
</PN>
<...other PN...>
</Flange-type>
<...other Flange-type...>
</Standard>
<...other standard...>
</Nozzle-Flange-Weight>

Then I wanted to use xpath and XML.SelectedSingleNode to search in this XML to get one node's value.I write it in a function,all parameters were com from textboxes that were in a windows form.The function was like below:

SQL

If Not (Standard = "") Then
               xpath = "/Nozzle-Flange-Weight/Standard[@value='" + Standard + "']/Flange-type[@type='" + Type + "']/PN[@PN='" + PN + "']/Weight[@DN='" + DN + "']"
               xmlnode = xmldoc.SelectSingleNode(xpath)

I checked this xpath and my textboxes but it didn't find the node I need,so I wanted to check this xpath and debug it .Could you give me some suggestions or help?
Thank you very much!

Are you sure that the current position is already within the "standard" element? Maybe just try it from the document root: //Nozzle-Flange-Weight/Standard/...

At the link below you can download cooktop. This is a nice freeware tool that ain't perfect, but very handy. You give your xml and xpath and with one button click it will produce the result or give the error. Very nice for writing and checking xpath.
