Question about create pivot table in xslt

[Lee]

I have a xml file, here is sample part:
<?xml version="1.0" encoding="UTF-8"?>
<ProducsList>
<Product id="1">
<SpecList>
<Spec>
<SpecLabel>Height</SpecLabel>
<SpecValue>10</SpecValue>
<SpecCat>Dimension</SpecCat>
</Spec>
<Spec>
<SpecLabel>Width</SpecLabel>
<SpecValue>6</SpecValue>
<SpecCat>Dimension</SpecCat>
</Spec>
<Spec>
<SpecLabel>Weight</SpecLabel>
<SpecValue>20.5</SpecValue>
<SpecCat>Weigth</SpecCat>
</Spec>
</SpecList>
</Prodcut>
<Product id="2">
<SpecList>
<Spec>
<SpecLabel>Height</SpecLabel>
<SpecValue>8</SpecValue>
<SpecCat>Dimension</SpecCat>
</Spec>
<Spec>
<SpecLabel>Width</SpecLabel>
<SpecValue>5</SpecValue>
<SpecCat>Dimension</SpecCat>
</Spec>
<Spec>
<SpecLabel>Weight</SpecLabel>
<SpecValue>18</SpecValue>
<SpecCat>Weigth</SpecCat>
</Spec>
</SpecList>
</Prodcut>
<Product id="3">
<SpecList>
<Spec>
<SpecLabel>Height</SpecLabel>
<SpecValue>5</SpecValue>
<SpecCat>Dimension</SpecCat>
</Spec>
<Spec>
<SpecLabel>Width</SpecLabel>
<SpecValue>2</SpecValue>
<SpecCat>Dimension</SpecCat>
</Spec>
<Spec>
<SpecLabel>Weight</SpecLabel>
<SpecValue>10</SpecValue>
<SpecCat>Weigth</SpecCat>
</Spec>
</SpecList>
</Prodcut>
</ProductsList>

I need to create a table look like that based on that xml file:

----------------------------------------------------
Label Product 1 product 2 product 3
----------------------------------------------------
Height 10 8 5
Width 6 5 2
Weight 20.5 18 10

I am totally losed, I don't know how to create that table. any one has
any idea about that? thank you very much.

Also how many Spec in SpecList is unkown.

Thanks for the help.

Break it down into parts. Express it in English -- or whatever language
you're most comfortable in -- and then use that as a guide to writing
the XSLT.

1) Pick one line of the table. How do you retrieve all the values needed
for that line? (Hint: You'll need to use a predicate.) What do you want
to surround those values with in order to display them in that line? (If
you're producing an HTML table, that would be <td> elements.) What does
the line have to be surrounded with to make it display as a line? (If
you're producing HTML, that would be a <tr> element.)

2) Repeat for the other lines of the table.

3) What do you need to surround the lines with in order to display the
table? (If you're producing HTML, that would be a <table> element.)

Joe,

Thanks a lot for your reply. I am pretty new to xslt, so I don't quite
understand what you mean. do you have any sample codes for that?
Thanks again.

 

[Joe Kesselman]

Thanks a lot for your reply. I am pretty new to xslt, so I don't quite
understand what you mean. do you have any sample codes for that?

If you're asking that general a question, it sounds like you really need
to start by reading some XSLT tutorials. See my 5/29 post to the
"Transforming xhtml with xslt" thread for a list of good places to look
for information. In particular, IBM's site has many good tutorials and
articles, and the XSLT FAQ website has many examples worth studying.

See also http://www.catb.org/~esr/faqs/smart-questions.html -- I'm sure
you didn't intend it, but your question reads entirely too much like
"please do my homework assignment for me."

Anybody else can help me out with this question? I know my knowledge
about xsl are really poor, but it is imposible for me to learn all
those stuff in one day. I will take some time to learn it step by
step. but for this particular question, I really need people with
experience give me some clue on how to deal with it. Thanks a lot!

Sorry, crossed threads; let me corrct that...

Dimitre,

I found you are using msxsl namespace, is that gonna be a problem for
none-microsoft browsers? Thanks.

Thank you guys, I finially figured out how to do it. at the very
beginning I thought I can't use param in for-each, so I don't event
try to use variable, acutually, variable is OK to use in for-each
loop. so my xslt file is here:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/
Transform">
<xslutput method="html" />
<xsl:template match="/">
<html>
<body>
<table border="1">
<xsl:for-each select="/ProductList/Product[position()=1]/SpecList/
Spec">
<xsl:variable name="label" select="SpecLabel"></xsl:variable>
<tr>
<td>
<xsl:value-of select="$label"/>
</td>

<xsl:for-each select="/ProductList/Product">
<td>
<xsl:apply-templates select="SpecList/Spec/SpecLabel[.=
$label]"/>
</td>
</xsl:for-each>
</tr>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>

<xsl:template match="SpecLabel">
<xsl:value-of select="../SpecValue"/>
</xsl:template>

</xsl:stylesheet>

No, but for another processor one would normally use the exslt:node-set()
extension function instead.

Just a few days ago Julian Reschke and David Carlisle discovered a
technique, which allows to specify exslt:node-set() in a way that it can be
used with the MSXML xslt processor:
