Yesterday I came across the following situation:
1) Load a XML File.
2) Parse the elements that match certain criteria.
3) Set the elements value to a new data
The only problem in the above situation was that I was dealing with CDATA inside the element.
Sample XML:
<employees>
<employee>
<description>
<![CDATA[Lorem Ipsum]]>
</description>
</employee>
....
</employees>
The C# fragment that will allow you to manipulate the above elment is:
public void ParseEmployeeDescription(XDocument document)
{
var result = from e in document.Descendants("description")
select e;
foreach (var element in result)
{
if(/*Some condition matches*/)
{
var temp = element.Value;
temp += "modified";
//Replace with new data in the CDATA tag
((XCData)element.FirstNode).Value = pTagData;
}
}
document.Save("new_employees.xml");
}
Hopefully this helps someone
