How to replace commas with spaces in XSL

Question

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         


        

Answer 1

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>
