sinus or cosinus in xslt?

Hi!

is it possible to use sinus or cosinus in my stylesheet?
As an example I have the following variable:

 <xsl:variable name="x" select="60"/> </pre> <BR><BR>Now I want to create a second variable which is the sinus of x. It must be something like this:<BR><BR> <pre class="ip-ubbcode-code-pre"> <xsl:variable name="sinx" select="SIN($x)"/> 



How can I do this???
Thanks for answering

Hello there,

The sin implementation is not provided as is into the XSLT 1.0 standard. However you might use the EXSLT implementation to perform a sin computation.

Have a look at : EXSL > Math page

… provided your XSLT engine supports EXSLT (eg Xalan).

Or, alternatively, you could use an extension function (call Java/PHP/DCOM code from your XSL).

Feel free to ask for more if you need enhanced help.

Hi Bertrand.

thanks for your help. Can you show me an example how to call Java from my xsl. would be nice :slight_smile:

Hi tam,

First of all, could you please tell me which XSLT engine are you using ? Calling java from an XSLT is vendor specific (ie not standard).

Besides, calling EXSLT is the best option, IMHO.

I can be of any help only under Xalan (Apache XSLT engine) or MSXML.

Hi Bertrand,

I use the Xalan-J Processor for my project.

Here comes a snippet to compute sin() under an EXSLT compliant XSLT engine (eg Xalan) :

XML :

============================
<?xml version="1.0" encoding="ISO-8859-1"?>
<?xml-stylesheet type="text/xsl" href="C:\Temp\sin\doc.xsl"?>

90

============================

XSL :

============================
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version=“1.0”
xmlns:xsl=“http://www.w3.org/1999/XSL/Transform
xmlns:math=“http://exslt.org/math
extension-element-prefixes=“math”>

<xsl:template match="/">
<xsl:value-of select=“math:sin(/Root/Angle)” />
</xsl:template>

</xsl:stylesheet>
============================

Output :

============================
0.8939966636005579
============================

Here you go.

Cheers.
