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.
I have following xml bellow and want to concat together as here:
Field1 [from position 1, length varies] + " " [until position 11] +
Field2 [from position 12] + " " [until position 16]+ Field3 [from
position 17, length always 10] + " " [until position 27] + Field4
Input
<Field1>2000090691</Field1>
<Field2>0010</Field2>
<Field3>2000090690</Field3>
<Field4>0010</Field14>
