Converts a node-set into a string (allows you to insert code blocks as text rather than being interpreted). Useful for things such as JSON conversions and displaying code snippets. @href: http://www.getsymphony.com/download/xslt-utilities/view/103039/ @href: http://www.getsymphony.com/discuss/thread/103015/

Converts a nodeset to string, especially useful for json conversions.
===================================================================================
Adapted from @Thomas Appel's nodetostring utility at http://www.getsymphony.com/download/xslt-utilities/view/79266/
This version adds formatting capabilities. Very useful for displaying code snippets.
