There isn't an infinite loop with the source that you sent, but
perhaps Stylus is really clever and is detecting one anyway because
contains($string, $from) returns true if $from is an empty string. The
template is a bit strange anyway, because it always gives the value
after the $from in the $string as well as than stepping on
recursively. Try the following:

<xsl:template name="string-replace">
  <xsl:param name="string"/>
  <xsl:param name="from"/>
  <xsl:param name="to"/>
  <xsl:choose>
    <xsl:when test="string($from) and contains($string, $from)">
      <xsl:value-of select="substring-before($string, $from)" />
      <xsl:value-of select="$to"/>
      <xsl:call-template name="string-replace">
        <xsl:with-param name="string"
                        select="substring-after($string, $from)" />
        <xsl:with-param name="from" select="$from"/>
        <xsl:with-param name="to" select="$to"/>
      </xsl:call-template>
    </xsl:when>
    <xsl:otherwise>
      <xsl:value-of select="$string"/>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>

I hope that helps,

Jeni
