Fw: function returning string with string-join()

As a side note this can even be done with just XPATH 1.0:

$ xpath++ "concat(substring('NoXNo1No2',1+string-length(concat(*[/ = 1],*[/
= 2],*[/ = 2]))*3,3),'.html')" 3.xml
NoX.html
$ xpath++ "concat(substring('NoXNo1No2',1+string-length(concat(*[/ = 1],*[/
= 2],*[/ = 2]))*3,3),'.html')" 2.xml
No2.html
$ cat 3.xml
<xml>3</xml>
$


xpath++ tool is based on xsltproc or DataPower processor:

Hello experts,

I find myself building functions like this (no real code!) to return a
string:

<xsl:function name="my:filename" as="xs:string">
  <xsl:param name="input" as="xs:integer" />
  <xsl:variable name="strings">
    <xsl:choose>
      <xsl:when test="$input eq 1">
        <xsl:value-of select="'NO1'" />
      </xsl:when>
      <xsl:when test="$input eq 2">
        <xsl:value-of select="'NO2'" />
      </xsl:when>
      <xsl:otherwise>
        <xsl:message select="'otherwise?'" />
        <xsl:value-of select="'NOx'" />
      </xsl:otherwise>
    </xsl:choose>
    <xsl:value-of select="'.html'" />
  </xsl:variable>
  <xsl:value-of select="string-join($strings, '')" />
</xsl:function>

In a variable this builds a sequence of strings using individual
xsl:value-of and in the end they are joined. Is this the way to do it if I
cannot concat() everything in a single, large xsl:value-of?

I have a feeling that it might be simpler?

Thanks for teaching me new/old tricks :-)

- Michael
