RE: Infinite Loop when trying to use String-Replace

I 'd suggest that you try Saxon instead either from the command line or
from with Stylus. You can use Saxon in Stylus:
- Tools > Options > External XSLT
- In "Default custom processor command line put something like:
  c:\xsltproc\oraxml\saxon.exe %1 %2 %3

You can download the compiled version of Instant Saxon (for Windows
platform) from its SourceForge project page at
http://sourceforge.net/projects/saxon.

Note that Stylus just won't do everything you'll need it to, though it's
getting better. One last thought - I've found it helpful to have several
XSLT processors on hand for debugging and experimentation. More than once I
gained a crucial insight from an a processor that I wasn't using regularly.

HTH,

I tried using your template, but Stylus is still detecting an infinite
loop.
Any other suggestions?

Jeff

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
