In the same Xml file, how can I remove the entire block of "enrich-details entity="division"" node?

pradiprenushe 11-Sep-12 5:29am

XmlNodeList xnList = doc.SelectNodes("request/enrichment-request/enrich-details");
foreach (XmlNode xn in xnList)
{
xn.RemoveChild(xn.FirstChild);

}

Try this

C#

XmlDocument doc = new XmlDocument();
doc.Load(XmlfileName);
XmlNodeList xnList = doc.SelectNodes("request/enrichment-request/enrich/enrichment-required");
            foreach (XmlNode xn in xnList)
            {
                if (xn.FirstChild.Value == "mf_compliant")
                { 
                xn.RemoveChild(xn.FirstChild);
                }
            }
doc.Save(XmlfileName);

pradiprenushe, your solution removes the entire "enrich" node, but i just want to remove the node which contains "mf_compliant" as innertext.
Thanks in advance.

C#

// Input File Path.
XDocument doc = XDocument.Load("input.xml");

var q = from node in doc.Descendants("enrichment-required")
        where node != null && node.Value == "mf_compliant"
        select node;

q.ToList().ForEach(x => x.Remove());

// Output File Path.
doc.Save("output.xml");

Here is a quick and dirty solution, i tested it briefly and that was the fastest I came up with. Probably there are some nicer solutions:

C#

XmlDocument document = new XmlDocument();
document.Load("C:\\Temp\\New.xml");
XmlNode nodeReq = document.SelectSingleNode("request");
if (nodeReq != null)
{
   XmlNode nodeEnReq = nodeReq.SelectSingleNode("enrichment-request");
   if (nodeEnReq != null)
   {
      XmlNode nodeEnrich = nodeEnReq.SelectSingleNode("enrich");
      if (nodeEnrich != null)
      {
         foreach (XmlNode node in nodeEnrich.ChildNodes)
         {
            if (node.InnerText == "mf_compliant")
               nodeEnrich.RemoveChild(node);
         }
      }
   }
}
document.Save("C:\\Temp\\New.xml");
