Answer 1

XSLT is a functional language -- among other things this means that variables are immutable -- once given a value they cannot be changed.

The solution to this specific problem:

Change:

<xsl:value-of select="concat($count,',',$first-val, ',',value)"/>

To:

<xsl:value-of select="concat(position(),',',$first-val, ',',value)"/>

When the corrected transformation is applied to the provided XML document, the wanted result is produced.

Answer 2

Can you show me your input xml and desired output xml?

I kind of cringe a little when I see a foreach in xsl - it's a template language, and rarely needs foreach...

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE stylesheet [
    <!ENTITY comma "<xsl:text>,</xsl:text>">
    <!ENTITY cr "<xsl:text>
</xsl:text>">
]>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"
>
    <xsl:output method="text" indent="no" />
    <xsl:template match="/">
        <xsl:apply-templates select="/swift/message/block4/tag [name='77']"/>
    </xsl:template>

    <xsl:template match="message/block4/tag [name='77']">
        <xsl:apply-templates select="../../block2/@type"/>
        <xsl:value-of select="../../block2/messageType"/>
        <xsl:value-of select="../../block2/messagePriority"/>&comma;
        <xsl:number format="000001"/>&comma;
        <xsl:value-of select="../../block3/tag [name='32']/value"/>&comma;
        <xsl:value-of select="value"/>&cr;
    </xsl:template>

    <xsl:template match="@type[.='input']">O</xsl:template>

    <xsl:template match="@type[.='output']">I</xsl:template>

    <xsl:template match="text()"/>

</xsl:stylesheet>

You need one row for each block4 name. So apply a template for that block4/tag [name='77']

Then - for every one of those, select the parent elements that you need.

xsl:number will count the number of times it selected.

The ENTITY items are there to control whitespace - otherwise the formatting is crap.

No need for a foreach. Hope this helps
