C# newbie

Hi,

I'm supposed to write a class to do search (using XPath queries) into an XML
file, also capturing attribute information & elements + ability to modify
information too.
Here is my question: Can I create a class which contains System.Xml and
XmlTextReader + XTextWriter classes ?
I mean, does it make sense to have all these stuff in one class together ?

Thanks in advance for your suggestions

I'm not sure why you'd do this.

The simplest route for basic XPath operations is to create an instance of
the XmlDocument class and call LoadXml on it, passing in the XML as a
string. XPath operations can then be performed by calling SelectNodes or
SelectSingleNode on the XmlDocument object.

If you need to do more advanced XPath operations, consider using the
XPathNavigator class in the System.Xml.XPath namespace.

Hi Doug,

Thanks for your quick response! the thing is I'm not familiar with
XPathNavigator however, I"m going to focus on it. Hope it does what I need
like retreiving element, attributes and stuff like that.
Anyhow thanks for your help.

Regards
Newbie

regarding your advice I'm reading some text about XPahtNavigator but it
doesn't give me any editing capabilities! it provides read only view of an
xml file. I need to modify some text within a searched xml file.

any suggestions ?

thanks
