Editing a CDataSection

**olamm2k** · Mar 14th, 2006, 06:41 AM

Hi,

What's the best way of editing a CDataSection in an XML file?

At the moment, the structure of my file is something like this:

Code:

<?xml version="1.0"?>
<news>
  <newsItems>
    <newsItem ccid="000000">
      <headline>Headline</headline>
      <date>14/03/06</date>
      <body><![CDATA[Some text...]]></body>
      <author>Oliver</author>
      <email>[email protected]</email>
    </newsItem>
  </newsItems>
</news>

My edit code looks like this (where lstExistingNews is a ListBox and the txt[SomeName] objects are TextBoxes):

VB Code:

Dim xmlDoc As XmlDocument = New XmlDocument()
    xmlDoc.Load(Server.MapPath("/CHC/xml/news.xml"))
 
      Dim xmlEdit As XmlNode = _
       xmlDoc.SelectSingleNode("/news/newsItems/newsItem[@ccid='" & _
       lstExistingNews.SelectedItem.Value & "']")
 
      xmlEdit.SelectSingleNode("headline").InnerText = txtHeadline.Text
      Dim xmlCData As XmlCDataSection = _
       xmlDoc.CreateCDataSection(Replace(txtBody.Text, vbCrLf, "<br />"))
      xmlEdit.SelectSingleNode("body").ReplaceChild(xmlCData, _
        xmlEdit.SelectSingleNode("body").FirstChild)
      xmlEdit.SelectSingleNode("author").InnerText = txtAuthor.Text
      xmlEdit.SelectSingleNode("email").InnerText = txtEmail.Text
 
    xmlDoc.Save(Server.MapPath("/CHC/xml/news.xml"))

This works well enough, but shouldn't there be a way to access the contents of the CDataSection directly? I think I read somewhere that it counts as normal text under one model, but as a node under DOM, or something like that(?)

I was hoping to do something like:

VB Code:

xmlEdit.SelectSingleNode("body/text()[2]").InnerText = _
   Replace(txtBody.Text, vbCrLf, "<br />")

Any ideas?
