RE: for i = 1 to 10, or while (is there an equivalent?

Actually, I think I'm already dead in the water.  Is there a way to modify a
variable after it is declared and set?

What I was hoping to do was (forgive the ugly psuedo xsl):

	while (<xsl:if test="contains($var,'\')")
	{
		var = <xsl:value-of
select="substring-before($var,'\')"/><xsl:text>\\</xsl:text><xsl:value-of
select="substring-after($var,'\')"/>
	}

But it looks like I can neither do the while (other than something really
dodgy like select="//*") or modify the variable.

Any guidance appreciated.

Hi,
 
I'm probably going about this the wrong way, but I have a C string in a
variable that I want to escape the backslashes and double-quotes prior to
output.  ie. foo\bar"xxx -> foo\\bar\"xxx I figured I could use the XPath
contain and substring functions to do what I want, but I can't find a way to
iterate until there are no more characters of interest.  Can this be done in
XSL/XPath?
 
Regards,
