I need to replace every other comma with a space in my XML output. Right now, I have latitude and longitude that looks like this:
-0.52437106918239,0.3915094
In XSLT 2.0 it would be trivial. You could use replace().
In XSLT 1.0, you could use template like so. Call the convert-space template on your list that needs every second comma replaced.
<xsl:template name="convert-space">
<xsl:param name="text"/>
<xsl:choose>
<xsl:when test="contains($text,',')">
<xsl:value-of select="substring-before($text,',')"/>
<xsl:value-of select="' '"/>
<xsl:call-template name="convert-comma">
<xsl:with-param name="text" select="substring-after($text,',')"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$text"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template name="convert-comma">
<xsl:param name="text"/>
<xsl:choose>
<xsl:when test="contains($text,',')">
<xsl:value-of select="substring-before($text,',')"/>
<xsl:value-of select="','"/>
<xsl:call-template name="convert-space">
<xsl:with-param name="text" select="substring-after($text,',')"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$text"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
