Why is tempspace here?

Question

if we assumed that "AB" is a value for an xml element called given names, the following code converts that value to "A.tempspacetempspaceB". instead of "AB"

foreach (XElement initial in doc.XPathSelectElements("//given-names")) { string v = initial.Value.Replace(".", ". ").TrimEnd(' '); initial.SetValue(v); } 

So why does tempspace come here instead of literal space?

Answer 1

First of all, the space is illegal inside the XML tag name, and if you are in a DOM or DOM object (which you :-) it is going to fight you until it disappears when you try to break the basic XML grammar - you can even call the cops if you insert: - )). I am surprised that he did not just throw at you when you tried. It simply cannot allow you to do this because it will no longer be XML.

Your code gave me the expected results when I tested it. I order a try, I put together a little test in a console application. I used the following XML:

 <?xml version="1.0" encoding="utf-8" ?> <root> <user> <given-names>AB</given-names> </user> <user> <given-names>YZ</given-names> </user> </root> 

Then I created a new console application project and dropped this in the program class:

 class Program { static void Main(string[] args) { XDocument doc = XDocument.Load("XMLFile1.xml"); foreach (XElement initial in doc.XPathSelectElements("//given-names")) { string v = initial.Value.Replace(".", ". ").TrimEnd(' '); initial.SetValue(v); } Console.WriteLine(doc.ToString()); } } 

He produced the desired result:

 <root> <user> <given-names>AB</given-names> </user> <user> <given-names>YZ</given-names> </user> </root> 

There must be something else causing the problem. What environment do you work in? How do you convert an XDocument to a string for output?

Answer 3

Have you tried decomposing method calls to find out if this works?

eg:.

 string v = initial.Value.Replace(".", ". "); v = v.TrimEnd(@"\s+"); initial.SetValue(v); 

Also did you check if your text encodings match? The XML analysis encoding is likely to be Unicode, while the default encoding for C # is US-ASCII. I'm not sure if this will make a difference, but it might be worth checking out.
