Sonika ColasoSubject: Repeat images using FOR EACH loop
Author: Sonika Colaso
Date: 27 Jul 2009 04:56 PM
Hello,

I'm new to XML & XSL and cannot figure out how to get this to work. Any help will be much appreciated!

I'm trying to loop through images and display it in each cell. For some reason, whatever i do, it just takes the first image and repeats that. I've tried many things, but cannot get it to read any other image. Here is a snippet of my XML code:

<report>
<quote >
<quote_attachment assoc_id="382,058">
<attachment location="3086.JPG"></attachment>
</quote_attachment>
<quote_attachment assoc_id="382,059">
<attachment location="FRONT_SKETCH_WITH_BUTTON_FLY3.JPG"></attachment>
</quote_attachment>
<quote_attachment assoc_id="382,060">
<attachment location="BACK_SKETCH7.JPG"></attachment>
</quote_attachment>
.
.
.

Now here is the XSL I am using to try to get it to loop the images into the table cells. It only picks the 3086.jpg image and repeats that into the cells. Please tell me what I am doing incorrectly, I've been struggling with this for a while now...thanks!!

<fo:table-row>
<xsl:for-each select="//quote_attachment/attachment/@location">

<fo:table-cell padding="0.25mm" border-style="solid" border-width=".25mm" height="2.0in">
<xsl:variable name="img_src" select="//quote_attachment/attachment/@location"/>
<fo:block font-weight="bold" font-size="6pt" text-align="center">
<fo:external-graphic src="{$img_src}" height="5.5in"/>
</fo:block>
</fo:table-cell>

</xsl:for-each>

</fo:table-row>

When you say <xsl:variable name="img_src" select="//quote_attachment/attachment/@location"/> you are selecting all of the @locations again.

Since you are inside the scope of the for-each block, you should simply say <xsl:variable name=img_src" select="."/>

Awesome! Thanks Tony! That worked!! :) But I have another question now...kinda related...now I have 2 images showing up, atleast not repeating. But because I have specified 2 columns, it only wraps up into 2 cells and drops the third image. See code below. Any idea what I need to do to tell it to put the third image on the next row cell and so on? Basically 2 images per row but wrap to the next row if there are more than 2? Thanks again for the help!!

<!--Table for images -->
<xsl:template name="imagetable">
<fo:table table-layout="fixed">
<fo:table-column column-width="proportional-column-width(50)"/>
<fo:table-column column-width="proportional-column-width(50)"/>


<fo:table-body>


<fo:table-row>
<xsl:for-each select="//quote_attachment/attachment/@location">

<fo:table-cell padding="0.25mm" border-left-style="solid" border-right-style="solid" border-bottom-style="solid" border-width=".25mm" height="2.0in">
<xsl:variable name="img_src" select="."/>
<fo:block font-weight="bold" font-size="6pt" text-align="center">
<fo:external-graphic src="{$img_src}" height="5.5in"/>
</fo:block>
</fo:table-cell>

</xsl:for-each>
</fo:table-row>


</fo:table-body>
</fo:table>

The usual method for handling things like this is to use the
'mod' function. If position() mod 2 = 0, then you're on an
even row - which in your case would be column 2. Otherwise,
you're on an odd row.

If you're going to be playing with XSLT, a good book to have
is the XSLT Cookbook by Sal Mangano.

Thanks Toni. Could you please elaborate on this a bit? Is it something I can just include inside the code I posted? I think if I can get this figured out, should make a decent headway. So do let me know how I can incorporate that function into my code. Appreciate the help!

Can you supply a sample input file a and small (mostly) working example?
Then it would be easier to see exactly what you are doing so we can make
a better suggestion.
