Hi all,
I have a string value, for example "000057"

I have an XML with different values:
<?xml version="1.0" encoding="utf-8" ?>
<klanten>
      <klant>000051</klant>
      <klant>000052</klant>
      <klant>000053</klant>
      <klant>000054</klant>
      <klant>000055</klant>
      <klant>000056</klant>
      <klant>000057</klant>
      <klant>000058</klant>
      <klant>000059</klant>
      <klant>000060</klant>
      <klant>000061</klant>
</klanten>

How can I determine if the given value is located in the XML, retruning true or false ?

Hello JamesBrian,

System.Xml.XmlDocument xDoc = new System.Xml.XmlDocument;
xDoc.Load("MyDoc.xml");
If (xDoc.SelectSingleNode("klanten[klant='000057']") != null) {
  //it exists }
else
 {//it doesn't}

Regards,

TimCottee
