Re: [xsl] What is the best way to get the value of a leaf element and store it into a variable?

["Michael Kay michaelkay90@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

I would choose between string($leaf-elmt) and data($leaf-elmt). If your
document is untyped (not schema-validated) then they are almost equivalent:
the difference is that string() returns a string whereas data() returns
untypedAtomic, which allows it to participate for example in arithmetic
operations.

text() best avoided, it means your code won't work properly if someone
presents you with XML containing comments.
