RE: Variables

What i want to acheve is:

if i have the following xml node i.e.

<><><><><<><><><><><<><><><><<><><><><><
<names option1="john" option2="peter"/>
<><><><><<><><><><><<><><><><<><><><><><

First of all check if the attribute "option1" exists(How do i do this?),
it's not a must it will be there. And if it does,
set the variable x = 400 - ( No.of option1 * 10 )

Given that the variable had been declared earlier.

  How can i perform the following operation in xslt.

  <xsl:if test=@steve != 0>
	x= x + 1
  </xsl:if>

  where x is a variable.

if x = x + 1 then 0 = 1 and the world would be inconsistent.
this would be bad, so XSLT, like other declarative programing languages
doesn't let you change the value of a variable once it is bound.

This is a FAQ.

If you said what you were trying to generate rather than which illegal
operation you were trying to peform, someone could offer some further
help.
