Re: [xsl] problem with scientific notation and leading whitespaces

["G. Ken Holman" <gkholman@xxxxxxxxxxxxxxxxxxxx>]

Have you tried:

  <xsl:value-of select="normalize-space( Apples * Bananas )"/>

... in which the expression is translated into a string and then the 
leading and trailing white-space characters are removed.

I hope this helps.
