Re: [xsl] How to split an RegEx into several lines for readability?

["Rashmi Rubdi" <rashmi.sub@xxxxxxxxx>]

Hi Dimitre,

I've just begun to read a book on Regular Expressions and in the book
they strongly discourage unintended white spaces.

Here's an excerpt "...Placing unintended white spaces in a regular
expression can radically alter the meaning of the regular expression
and can turn what ought to be matches into nonmatches, and vice versa.
When creating regular expression patterns, you need to be meticulous
about handling whitespace..." taken from Beginning Regular Expressions
by Andrew Watt.
