XSLT 1.0 refers to Java JDK 1.1 for the specification of format-number.
Unfortunately the JDK 1.1 specification (which is quite hard to find
nowadays) is very incomplete. One thing it doesn't say, but which later
versions of the JDK document do say, is that many aspects of the negative
sub-pattern are ignored: for example, grouping separators are taken from the
positive subpattern even if the number is negative. So an XSLT
implementation that's built on top of the JDK implementation is likely to
have this "feature", while an implementation that's written to the JDK 1.1
specification probably won't.
The XSLT 2.0 spec doesn't rely on the JDK any more, it has a free-standing
description of the function, and we decided not to carry over this JDK bug.
I think the result you are getting from Saxon is consistent with the XSLT
2.0 specification. What do you mean when you say you are losing the
formatting - what output did you expect? If you want a grouping separator
for negative numbers, you must include it in the negative sub-picture.
A correct XSLT 1.0 implementation should do what JDK 1.1 says, which is
rather different from what JDK 1.1 (let alone any later JDK) does.

Subject: [xsl] Difference in Xalan & Saxon for format-number function
Hi,
I have a template to format a decimal-string(for both
+ve and -ve numbers)
Postive numbers should be transformed as it is but
-ve number should be wrapped in ().
This is the XSL code.
<xsl:template name="formatCurrency">
<xsl:param name = "stCurrency" />
<xsl:variable name="formatedCurrency">
<xsl:choose>
<xsl:when test="starts-with($stCurrency,'-')">
<xsl:value-of select="format-number
($stCurrency, '#,##0.00;(#0.00)')"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="format-number
($stCurrency, '#,##0.00')"/>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<xsl:value-of select="$formatedCurrency"/>
</xsl:template>
Both are working fine for +ve numbers but -ve ones
have issues.
For a value of -263504.720000, I am getting
(263,504.72 in Xalan and (263504.72) in saxon8.
Saxon8 is working fine with the braces but looses the
formating and Xalan retains the formatting but looses
the closing ).
Any clues, what is the cause and what will be the
correct solution so that it works in both.
Thanks in advance.
Bhupendra.
