Assigning XML string as the content of an attribute

[McGeeky]

Hi. I want to assign an XML string to an XML attribute. This XML string must
undergo "escape" conversion so that the < and & symbols are converted in to
escaped equivalents.

Does the .Net library have a conversion method that does this? Note that I
want to construct the resulting XML string myself without having to use an
XmlDocument.

E.g.

string myXml = "<root><rec ord/><record/></root>";

string myDoc = "<doc myXml='" + Converter.escap eMyXml (myXml ) + "'/>";

Sure, you should always use XmlTextWriter if you want to construct/write
some XML, here is a simple example:

string myXml = "<root><rec ord/><record/></root>";

StringWriter stringWriter = new StringWriter();
XmlTextWriter xmlWriter = new XmlTextWriter(s tringWriter);

xmlWriter.Write StartElement("d oc");
xmlWriter.Write AttributeString ("myXml", myXml);
xmlWriter.Write EndElement();
xmlWriter.Flush ();
xmlWriter.Close ();

string xml = stringWriter.To String();

Console.WriteLi ne("XML created is:\r\n{0}", xml);

Result then is e.g.

<doc myXml="&lt;root &gt;&lt;reco rd/&gt;&lt;reco rd/&gt;&lt;/root&gt;" />
So .NET provides all what you need. Only I have doubts that putting XML
escaped into an attribute is usually a good idea as that way it loses
its structure and is plain text for any XML tool.

Thanks for that! Its really helped.

The reason for the XML in the attribute is that I am passing it as a
parameter to a stored procedure which then uses openxml to read from it.
