Question: i have xml file which contains CDATA

i need to update the CDATA as like in this example.

i am modifying "span" here

```
<elements>
    <![CDATA[-div[id|dir|class|align|style],-span[class|align]]]>
  </elements>

```

should be updated as 

```
<elements>
    <![CDATA[-div[id|dir|class|align|style],-span[class|align|style]]]>
  </elements>

```

i am using framework 2.0.. how to do this using xmldocument.

thank you

Answer: 
You will need to extract the cdata as a regular string, then adjust it using normal string operations (or a regex) before re-inserting as cdata. That is the nature of cdata sections.
c# 2.0

This line updates the CDATA InnerText

```
xmlDoc.DocumentElement.SelectSingleNode("//elements").FirstChild.Value  = 
    "-div[id|dir|class|align|style], span[class|align|style]";

```

Full code

```
string xmlPath = @"C:\yourFolder\yourFile.xml";
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(xmlPath);
xmlDoc.DocumentElement.SelectSingleNode("//elements").FirstChild.Value  = 
    "-div[id|dir|class|align|style], span[class|align|style]";
xmlDoc.Save(xmlPath);

```
