Re: concat with unspecific length

Length various based on what? Until position 11, 16, or 27 of what?
>From position 12 or 17 of what? (No field you show is > 10 chars, so
I'm guessing those positions are of the concatenation of all fields.)

Presuming
1) you can tuck the desired variable length from Field1 into a
   variable $F1len,
2) the other positions you want are from the concatenation of all 4
   strings,
3) we are in the template that matches the parent of the four <FieldN>
   elements, and
4) I understand what you're asking for (low probability),
then:

  <xsl:template match="FieldsParent">
    <xsl:variable name="F1len" select="6"/>
    <xsl:variable name="all" select="concat( Field1, Field2, Field3, Field4 )"/>
    <xsl:value-of select="concat(
      substring( $all, 1, $F1len ),
      ' ',
      substring( $all, 1, 11 ),
      ' ',
      substring( $all, 12 ),
      ' ',
      substring( $all, 1, 16 ),
      ' ',
      substring( $all, 17, 10 ),
      ' ',
      substring( $all, 1, 27 ),
      Field4
      )"/>
  </xsl:template>

should be pretty close.

I'm betting I don't want to know why you want to do this.
