Breaking up XML string in C#

Question

I have got an XML node called 'structNumber' which has data similar to '4.2'

I select the node using:

XmlNode xnChapNr = xDoc.SelectSingleNode("//./structNumber");

And at present I am displaying it by:

 string chapNr = (xnChapNr == null) ? "X" : xnChapNr.InnerText

This then displays the entire string '4.2'.

What I need however, is a way to only select the '4' for this string and the '2' for another.

Is there an extension for InnerText? I have read through the documentation but nothing appears to work as I wish it to.

If it is helpful to know; what this code does in its entirety is produce a tree structure of an XML document. I.e: Chapter 4, Section 4.1, Sub section 4.1.1, Section 4.2, ect...

Any and all help will be much appreciated.

Answer 1

string chapNr = (xnChapNr == null) ? "X" : xnChapNr.InnerText.ToString().Split(new char[]{'.'})[0] will return you 4 and

string chapNr = (xnChapNr == null) ? "X" : xnChapNr.InnerText.ToString().Split(new char[]{'.'})[1] will return you 2

Answer 2

What you are looking for is not related to XML but to String operation. What you are looking for is the Split function http://msdn.microsoft.com/en-us/library/b873y76a.aspx
