Is it possible to format a number as hexadecimal?

[David Lowndes]

Is there any way in XSLT to convert a numerical value into a
hexadecimal representation?

Something like a format-number-hex() function perhaps?

It should be possible to implement a named template to perform the
conversion

Or use an extension function.
Which XSLT processor are you targetting?

I'm currently using the MS .Net XSLT facilities but I'm considering
switching to another engine for V2 facilities.

You could use an extension function then implemented in C# e.g.

<msxsl:script implements-prefix="mf" language="C#">
public string toHex (double n)
{
return ((int)n).ToString("X");
}
</msxsl:script>

<xsl:template match="some-element"
xmlns:mf="http://example.com/2008/functions">

<xsl:value-of select="mf:toHex(number(.))"/>

</xsl:template>

That's the first I've ever heard of such things - that looks much more
elegant :) - I'll give that a go.

I'm considering using a different XSLT processor because of a bug
(https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=314173).
Is there an elegant way of doing the hex output in XSLT 2?

Instead of using a named template and xsl:call-template in XSLT 1.0 you
can write a named function in XSLT 2.0 and call it with XPath function
call syntax everywhere you need it.

Thanks once again for all the help Martin.

I've tried the named template & the C# script methods, and I'll go
with the C# script for now as it provides better (easy) control over
the formatting (the result looks better presented with 8 fixed
characters - "X8").
