Hello Experts,

i have a problem with nodes from a xml file.

I have some <eventitem> nodes and want to loop every item in a variable, but i only get the first one...

<events>Liste</events>
<eventitem>Mitgliederversammlung</eventitem>
<eventitem>Sechzig Jahre</eventitem>

//SEMINARSELEKTION

                                    workshopstring = node["eventitem"].InnerText;
                                    

                                        if (workshopstring.Contains("Tag"))
                                        {

                                            TDMRTeilnahme = true;

                                            TDMRTeilnahme1.Set(executionContext, TDMRTeilnahme);
                                            tracingService.Trace("TDMRTeilnahme zugeordnet");

                                        }
                                        else if (workshopstring.Contains("Masch"))
                                        {

                                            tedx = true;

    RE: C# XML Nodes

    Hi,

    Not sure why you are doing the following:

    Entity Workshop1 = retrieveworkshop.Entities[0];

    Entity Workshop2 = retrieveworkshop.Entities[0];

    Entity Workshop3 = retrieveworkshop.Entities[0];

    Entity Workshop4 = retrieveworkshop.Entities[0];

    They all return the exact same value, since your are setting this to the first entity:

    All you need is:

    Entity workshop = retrieveworkshop.Entities[0];

    Can you expand on what you are trying to do?

    For querying Xml you need to add a loop or you can use Linq To Xml.

    Check the following doc on how to query descendants:

    docs.microsoft.com/.../how-to-find-descendants-with-a-specific-element-name

    Hope this helps.

    RE: C# XML Nodes

    Hello Léon,

    Which class are you using to read your XML?

     

    1. If you are using System.Xml.Linq.XDocument you can do this: 
      IEnumerable<System.Xml.Linq.XElement> elements = doc.Document.Elements("eventitem");
foreach(System.Xml.Linq.XElement element in elements) {
   // Loop...
}

       

    2. If you are using System.Xml.XmlDocument, you can do this: 
      System.Xml.XmlNodeList nodes = doc.DocumentElement.SelectNodes("//eventitem");
foreach(System.Xml.XmlNode node in nodes)
{
   // Loop...
}
