xsl:variable increment

How to increment global xsl:variable?

I've daclared variable:

<xsl:variable name="my-var" select="0" />

Somewhere else I do something like this:

<xsl:variable name="my-var" select="$my-var +1" />

but this creates new local variable and initialize it with value of global variable.

How to increment xsl:variables? Is it even possible?

Basically, you don't.

Nope.

You might want to look at (a) rewriting you transform without the variable or (b) look at writing a recursive transformation.

I was warried about that. I have to change my XSLT.
Thanks.

So, how would you solve problem like that.

I've got XML file with presons data (names and addresses). For example:

<users>
<user>
<fname>Name 1</fname>
<lname>Surname 1</lname>
<street>street 1</street>
</user>
<user>
<fname>Name 2</fname>
<lname>Surname 2</lname>
<street>street 2</street>
</user>
<user>
<fname>Name 3</fname>
<lname>Surname 3</lname>
<street>street 3</street>
</user>
</users>

Using this file, I have to generate PDF with envelope labels. Label sheet have two columns. If users count will be an even number, there will be no problem. If the users number will be odd number there will be a problem. How to slove it?

Regards,
G.

<xsl:choose>
<xsl:when test="count(//user) mod 2 = 0">
<xsl:apply-templates mode='even'/>
</xsl:when>
<xsltherwise>
<xsl:apply-templates mode='odd'/>
</xsltherwise>
</xsl:choose>

Great, thanks. I have to read more about XSLT.

<xsl:choose>
<xsl:when test="count(//user) mod 2 = 0">
<xsl:apply-templates mode='even'/>
</xsl:when>
<xsltherwise>
<xsl:apply-templates mode='odd'/>
</xsltherwise>
</xsl:choose>

I have used

<xsl:when test="(position mod 2)= 0">

Your solution did't work at my computer. Why? I don't know.

Now I wonder how to start write templates:

I've got

<xsl:template match="user" mode="even">
<fo:table-row>
<fo:table-cell background-color="green">
<fo:block text-align="left" text-indent="2pt"><xsl:value-of select="fname"/> </fo:block> </fo:table-cell> </fo:table-row> </xsl:template>

<xsl:template match="user" mode="odd">
<fo:table-row>
<fo:table-cell background-color="orange">
<fo:block text-align="left" text-indent="2pt"><xsl:value-of select="fname"/></fo:block> </fo:table-cell> </fo:table-row>

In 'odd mode' I shall start new table row. In 'even mode' I should end the row. But the XML document won't be valid. How to rewrite the code to display user envelope labels in two columns.

Sample input XML file:

<?xml version="1.0" encoding="windows-1250"?>
<users>
<user>
<fname>Albert</fname>
<lname>Einstein</lname>
<street>street 1</street>
</user>
<user>
<fname>Paul</fname>
<lname>Dirac</lname>
<street>street 2</street>
</user>
<user>
<fname>Issack</fname>
<lname>Newton</lname>
<street>street 3</street>
</user>
</users>

Using FOP and XSLT I would like to have PDF (!), that contains envelope labels. There will be ten envelopes on each page. I think it will be the best to put it in table - 2 colums and 5 rows. 1st row, 1st colum will contain Albert Einstein name adn adres; 1st, 2nd column will contain Paul Dirac; 2nd row 1st column will contain Newtons' data.

P.S. XSLT is like atomic bomb. I fell it is powerful, but I can't have a full contron on it (yet ;-)).
