Wrap Xmlnode with <b> tags-CodePudding

I have the following:

            XmlNode catchword = doc.CreateElement("CATCHWORDS");
            XmlNode subjectindex = doc.CreateElement("SUBJECT_INDEX");
            subjectindex.InnerText = DropDownList6.SelectedValue;
            catchword.AppendChild(subjectindex);

This is the output:


    <CATCHWORDS>
      <SUBJECT_INDEX>ADMINISTRATIVE LAW</SUBJECT_INDEX>
    </CATCHWORDS>

But i want to output these instead:


    <CATCHWORDS>
      <b><SUBJECT_INDEX>ADMINISTRATIVE LAW</SUBJECT_INDEX></b>
    </CATCHWORDS>

How i can achieve this?

I try to follow Wrap XmlNode with tags - C#, but did not understand.

Can someone give example based on my code?

CodePudding user response：

You can't just put HTML tags inside XML. If you want to put HTML tags inside XML, you have to encode them as entities.

subjectindex.InnerText = "<b>"
  DropDownList6.SelectedValue   "</b>";

CodePudding user response：

I'd suggest using LINQ to XML instead of XmlDocument - it's a much more modern API, and far nicer to use as a result.

Your current code would be this:

var element = new XElement("CATCHWORDS",
    new XElement("SUBJECT_INDEX", DropDownList6.SelectedValue)
);

And to amend to wrap that in b:

var element = new XElement("CATCHWORDS",
    new XElement("b",
        new XElement("SUBJECT_INDEX", DropDownList6.SelectedValue)
    )
);
