Elements with hyphens cannot be created in an XML document

[Hancoque]

Creating new elements in an XML document with hyphens in their names doesn't work using $(...). The regex string saved in the rsingleTag variable uses only \w to evaluate whether createElement() is to be used or not and the alternative method apparently doesn't work with XML documents.

A solution would be to replace \w with [\w\-] in the regex string.

Don't try to parse XML with $(...) because it isn't meant or documented to do that. Try $.parseXML() instead.
