I am not sure if this is basic question but even a hint in the form of
statement / query may be of help.
I have an XML like this
<?xml version="1.0" encoding="UTF-8"?>
<clothes>
<category name="shirts">
<sno times="1">
<brand>Arrow</brand>
<size>X-L</size>
<color>red</color> </sno>
<sno times="2">
<brand>Arrow</brand>
<size>Med</size>
<color>blue</color> </sno>
<sno times="3">
<brand>Arrow</brand>
<size>L</size>
<color>red</color> </sno>
<sno times="4">
<brand>Lee</brand>
<size>X-L</size>
<color>green</color> </sno>
</category>
</clothes>
this XML is genereted based on query from a user and comes from a database.
I want to display to the user only the available "brands" of shirts
Ie. output shall be only
"Arrow" and "Lee" in my case. and the user can then further query on the
subitems like "size" and "color". SO I want a
< Select "brand" from "clothes/category/sno" where "there is no repetiion"
> (:-)
sort of query. I hope I could make myself clear.
what XSL query can I write for this!
Thanks for the attenttion

$Hi,
$
$I have an XML that looks like this (I simplified the real one):
$
$<AAA>
$ <code>123</code>
$ <BBB>
$ <str1>abc</str1>
$ <str2>def</str2>
$ <str3>ghi</str3>
$ <BBB>
$ <CCC>
$ <type>1</type>
$ <code>123</code>
$ <ret>5</ret>
$ <DDD>
$ <str1>abc</str1>
$ <str2>def</str2>
$ <str3>ghi</str3>
$ </DDD>
$ </CCC>
$ <CCC>
$ <type>3</type>
$ <code>123</code>
$ <ret>3</ret>
$ <DDD>
$ <str1>abc</str1>
$ <str2>def</str2>
$ <str3>ghi</str3>
$ </DDD>
$ </CCC>
$ <CCC>
$ <type>2</type>
$ <code>123</code>
$ <ret>1</ret>
$ <DDD>
$ <str1>ABC</str1>
$ <str2>DEF</str2>
$ <str3>GHI</str3>
$ </DDD>
$ </CCC>
$ <CCC>
$ <type>0</type>
$ <code>123</code>
$ <ret>4</ret>
$ <DDD>
$ <str1>abc</str1>
$ <str2>def</str2>
$ <str3>ghi</str3>
$ </DDD>
$ </CCC>
$</AAA>
$
$I need to find the smallest 'ret' value where:
$
$AAA/code = AAA/CCC/code and
$AAA/BBB/str1 = AAA/CCC/DDD/str1 and
$AAA/BBB/str2 = AAA/CCC/DDD/str2 and
$AAA/BBB/str3 = AAA/CCC/DDD/str3
$
$which is here 3.
$
$I am using XSLT, and I have been struggling for hours now, I searched the
$archives, I found one similar question, but no answer and I could
$not find a
$solution myself either. The only way I can think of doing it is using
$something like do-while, but such an element/function is not supported by
$XSLT.
$
$Is there a solution?
$
$Thanks in advance,
$
$Zeynep
