AW: XSLT Question

Hi Alden,

for a first solution, you could try replacing the outer loop:
<xsl:for-each select="//Fruit">
by:
<xsl:for-each select="//Fruit[not(@ID = preceding-sibling::Fruit/@ID)]">
to process only the first occurrence of a Fruit's ID.

A far better solution would be to use "Muenchian Grouping". Search:

Betreff:        [xsl] XSLT Question



I am currently using an XSLT stylesheet to transform one type of XML into
another.  The first type looks like this:

<FruitList>
        <Fruit ID="5" KEY="apple" VALUE="true">
        <Fruit ID="5" KEY="orange" VALUE="false">
        <Fruit ID="4" KEY="orange" VALUE="false">
        <Fruit ID="5" KEY="banana" VALUE="false">
        <Fruit ID="4" KEY="pineapple" VALUE="false">
        <Fruit ID="13" KEY="orange" VALUE="false">
        <Fruit ID="13" KEY="watermelon" VALUE="true">
        <Fruit ID="4" KEY="kiwi" VALUE="false">
        <Fruit ID="4" KEY="grapefruit" VALUE="true">
        <Fruit ID="13" KEY="papaya" VALUE="false">
        <Fruit ID="13" KEY="honeydew" VALUE="true">
</FruitList>

I'd like to write a stylesheet to transform it as follows:

<FruitList>
        <Fruit ID="5">
                <Property KEY="apple" VALUE="true">
                <Property KEY="orange" VALUE="false">
                <Property KEY="banana" VALUE="false">
        </Fruit>
        <Fruit ID="4">
                <Property KEY="orange" VALUE="false">
                <Property KEY="pineapple" VALUE="false">
                <Property KEY="kiwi" VALUE="false">
                <Property KEY="grapefruit" VALUE="true">
        </Fruit>
        <Fruit ID="13">
                <Property KEY="orange" VALUE="false">
                <Property KEY="watermelon" VALUE="true">
                <Property KEY="papaya" VALUE="false">
                <Property KEY="honeydew" VALUE="true">
        </Fruit>
</FruitList>


So far, using a <xsl:for-each select="//Fruit">  with a nested <xsl:for-each
select="//Fruit[(_at_)ID=$a]"> where $a = the current ID, I've been able to get
the XML to look like the following:

<FruitList>
        <Fruit ID="5">
                <Property KEY="apple" VALUE="true">
                <Property KEY="orange" VALUE="false">
                <Property KEY="banana" VALUE="false">
        </Fruit>
        <Fruit ID="5">
                <Property KEY="apple" VALUE="true">
                <Property KEY="orange" VALUE="false">
                <Property KEY="banana" VALUE="false">
        </Fruit>
        <Fruit ID="5">
                <Property KEY="apple" VALUE="true">
                <Property KEY="orange" VALUE="false">
                <Property KEY="banana" VALUE="false">
        </Fruit>
        <Fruit ID="4">
                <Property KEY="orange" VALUE="false">
                <Property KEY="pineapple" VALUE="false">
                <Property KEY="kiwi" VALUE="false">
                <Property KEY="grapefruit" VALUE="true">
        </Fruit>
        <Fruit ID="4">
                <Property KEY="orange" VALUE="false">
                <Property KEY="pineapple" VALUE="false">
                <Property KEY="kiwi" VALUE="false">
                <Property KEY="grapefruit" VALUE="true">
        </Fruit>
        <Fruit ID="4">
                <Property KEY="orange" VALUE="false">
                <Property KEY="pineapple" VALUE="false">
                <Property KEY="kiwi" VALUE="false">
                <Property KEY="grapefruit" VALUE="true">
        </Fruit>
        <Fruit ID="4">
                <Property KEY="orange" VALUE="false">
                <Property KEY="pineapple" VALUE="false">
                <Property KEY="kiwi" VALUE="false">
                <Property KEY="grapefruit" VALUE="true">
        </Fruit>

..

</FruitList>

In other words, it prints out a seperate Fruit tag in the transformed XML
for each of the Fruit tags in the original when I want it to only print out
one fruit tag for each ID.  How do I get the XSLT to "skip" rows I've
already processed?  I tried saving the processed ID in a variable and
testing to see if the new ID is equal to the old ID, but because of scoping
issues it won't work.  Any ideas?


Thanks,

Alden
