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
