select nodes count

[David]

This is my xml sample:

<po>
<PurchaseOrderD etail>
<ProductLineIte m>
<LineNumber>1 </LineNumber>
<ProductIdentif ication>
<aaa>...</aaa>
<bbb />
</ProductIdentifi cation>
<cc />
</ProductLineItem >
....
</PurchaseOrderDe tail>
<PurchaseOrderD etail>
<ProductLineIte m>
<LineNumber>2 </LineNumber>
<ProductIdentif ication>
<aaa>...</aaa>
<bbb />
</ProductIdentifi cation>
<cc />
</ProductLineItem >
....
</PurchaseOrderDe tail>
</po>

I want to select "PurchaseOrderD etail" tag count, like this sample, I
should get "2". How should I get the count of it?

Thanks, David.

Re: select nodes count

I use selectnodes:

XmlElement root = doc.DocumentEle ment;
XmlNodeList nodeList = root.SelectNode s("/PO/PurchaseOrderDe tail");
int li_TotalCount = nodeList.Count;

But the li_TotalCount always "0"
I want get "2"...

Thanks, David.

Re: select nodes count

Hi,
You can do it like this.

XmlNodeList nodeList = doc.GetElements ByTagName("Purc haseOrderDetail ");
int li_TotalCount = nodeList.Count;

I think this will give you a count of 2.

Here you use "PO" in capitals, your example uses "po" in lowercase.
Is that a typo in your post? If not, then there is your problem: XML is case-sensitive
and yours has only "/po/PurchaseOrderDe tail" nodes and no "/PO/PurchaseOrderDe tail"
