Hi,

How do you add 130500 in front of NSC data element of an xml file? For example if I have the following xml file.

<Root>
<AOP5>
<ID></ID>
<SN></SN>
<NSC>8970</NSC>
</AOP5>
<AOP5>
<ID></ID>
<SN></SN>
<NSC>8789</NSC>
</AOP5>
<AOP5>
<ID></ID>
<SN></SN>
<NSC>7865</NSC>
</AOP5>
</Root>

How do I obtain:

<Root>
<AOP5>
<ID></ID>
<SN></SN>
<NSC>1305008970</NSC>
</AOP5>
<AOP5>
<ID></ID>
<SN></SN>
<NSC>1305008789</NSC>
</AOP5>
<AOP5>
<ID></ID>
<SN></SN>
<NSC>1305007865</NSC>
</AOP5>
</Root>

Thanks,

Victor

Old school way would be:
        Dim dom As New XmlDocument
        dom.Load("C:\temp\test.xml")

        Dim nodes As XmlNodeList = dom.SelectNodes("//NSC")
        For Each node As XmlNode In nodes
            node.InnerText = "130500" & node.InnerText
        Next

        dom.Save("C:\temp\test.xml")

Open in new window

I can knock together a Linq-to-Xml version if you prefer.

It's not that much different in this scenario, but here it is:
        Dim dom As XDocument = XDocument.Load("C:\temp\test.xml")

        Dim nodes As IEnumerable(Of XElement) = dom.Descendants("NSC")
        For Each node As XElement In nodes
            node.SetValue("130500" + node.Value)
        Next

        dom.Save("C:\temp\test.xml")

Open in new window

It would be slicker in C# because there is a foreach extension method, but hey ho!
