Math.abs() in xsl

Math.abs() in xsl

Hi,

Everything inside <lxslt:script language="javascript"> ... </lxslt:script
language="javascript"> is actually JavaScript not XSLT.  So the processor
you are using must support JavaScript extensions in order for this to
work.  There is an EXSLT extension for getting the absolute value.  See
http://exslt.org/ under the math module.  However EXSLT is also an
extension to the XSLT language so different processors may not support it.
If it is not in the language specification for XSLT or XPath (
http://www.w3.org/TR/xslt, http://www.w3.org/TR/xpath) then it is an
extension.  Please see http://xml.apache.org/xalan-j/ which has a lot of
information about extensions and which extensions are supported by the
Xalan interpreter and XSLTC.

Thanks.


Erin Harris

Math.abs() in xsl







Hi ,

i am using Math.abs(inumber) in my xsl to get the absolute value . This
works fine with xalan.

If i want to move any other engine which supports transformations does
this
Math.abs works with that Engine .

Is this is specific to xalan or its common functionality of xsl . I am
using
this Math.abs() inside a js function extension .
like <lxslt:component>
<lxslt:script language="javascript"> function fnabsolute(inum){ return
Math.abs(iNum) }.</lxslt:script></lxslt:component>

This works with xalan . What is the Math exactly here . Is the specific to
xalan xsl standard so that any engine should support that .

I am new to xsl so that i am asking this doubt .

Thanks,
Sasi.A
