Replacing 3 characters by 1 in a string with XSLT 1.0 - replace

Question

I'm working on a xsl template and one specific string is giving me a hard time.
<prixmenu>29.00-90.00</prixmenu>
Desired output :
<prixmenu>29€-90€</prixmenu>
The whole code I have is :
XML (input) :
<?xml version="1.0" encoding="UTF-8"?>
<data>
<etablissement not="15.0" etoile="2" >

<xsl:apply-templates
select="#*[not(.='0')] | node()[not(self::adresse)][not(self::tel)][not(self::fermetures)]" />

Any suggestions on how to proceed ? Should I import FXSL or switch to XSLT 2.0 as it probably be less of a pain to get to the desired result ?
I've tried splitting it with the following code (I belive it's called a 'recursive template" :
<xsl:template match="prixrestau/prixmenu" name="split">
<xsl:param name="pText" select="."/>
<xsl:if test="$pText">
<xsl:value-of select="number(substring-before(concat($pText, '-'), '-'))"/>
<xsl:call-template name="split">
<xsl:with-param name="pText" select="substring-after($pText, '-')"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
This outputs
<prixmenu>2990</prixmenu>
And i've also tried
<xsl:value-of select="translate(../prixrestau/prixmenu,'.00.','€')"/>
and the output is :
29€-9€
Because '.00.' and '€'don't have the same length (MDN reference)...

Answer 1

How about:
<xsl:template match="prixmenu">
<xsl:copy>
<xsl:value-of select="format-number(substring-before(., '-'), '0€')"/>
<xsl:text>-</xsl:text>
<xsl:value-of select="format-number(substring-after(., '-'), '0€')"/>
</xsl:copy>
</xsl:template>
If you like, you could change the first xsl:value-of instruction to:
<xsl:value-of select="format-number(substring-before(., '-'), '0€-')"/>
and get rid of the xsl:text part - but I think it's better to keep it to make the code more readable.
