Problem with URL characters to be saved in XML formatted doc.

[Joe]

I want to save some URLs into a XML formatted document.

I find out that its having some problems due to some of the characters
used
in the URL.

Is there a quick way to get around that? Thanks.

Here are some of the URL characters in the parameters

www.site.com/='N+Ss+Volume'& sym=

http://www2.site.com/

http://www.site.com/.?scanType=all_s...ange=all_&x=14

Are there any easy to use prewritten code to take care of this (the special
characters used in the URL I need to store in the XML formatted are causing
load and read problems with the XMLdocument object)?

The character & needs to be escaped as & (& a m p ; for web forum
readers) but any of the XML tools will do that automatically if you put
it into a text node/content of an element or attribute e.g. the
following C# code

string exampleURLWithQ ueryString =
@"http://example.com/whoisgod?name=K ibo&domain=usen et";

XmlDocument xmlDocument = new XmlDocument();
xmlDocument.App endChild(xmlDoc ument.CreateEle ment("example") );
xmlDocument.Doc umentElement.Se tAttribute("lin k",
exampleURLWithQ ueryString);
xmlDocument.Doc umentElement.Ap pendChild(
xmlDocument.Cre ateTextNode(exa mpleURLWithQuer yString)
);

xmlDocument.Sav e(Console.Out);

will produce the markup

<example
link="http://example.com/whoisgod?name=K ibo&amp;domain= usenet">http://example.com/whoisgod?name=K ibo&amp;domain= usenet</example>

so all ampersands are properly escaped as &amp; (& a m p ; for web readers).

Same if you use an XmlTextWriter e.g. the C# code

string exampleURLWithQ ueryString =
@"http://example.com/whoisgod?name=K ibo&domain=usen et";

XmlTextWriter xmlWriter = new XmlTextWriter(C onsole.Out);
xmlWriter.Write StartElement("e xample");
xmlWriter.Write AttributeString ("link", exampleURLWithQ ueryString);
xmlWriter.Write String(exampleU RLWithQueryStri ng);
xmlWriter.Write EndElement();
xmlWriter.Close ();
gives the serialized markup

<example
link="http://example.com/whoisgod?name=K ibo&amp;domain= usenet">http://example.com/whoisgod?name=K ibo&amp;domain= usenet</example>

Thus if you use the proper tools to create your XML then there should
not be a problem.
