Hey all,
First off, I must admit that this xsl stuff is really throwing me around 
in a loop. So far it is more than a tad over my head. I am pretty sure 
that what I am trying to do can be done, I just can't seem to find any 
straight (well, easy to grasp) info on it.

I have xml like this;
<orders>
    <order>
        <ordernumber>54321</ordernumber>
        <ordereditems>
            <ordereditem>
                <partnumber>smart part</partnumber>
            </ordereditem>
            <ordereditem>
                <partnumber>smart part</partnumber>
            </ordereditem>
            <ordereditem>
                <partnumber>stupid part</partnumber>
            </ordereditem>
        </ordereditems>
    </order>
    <order>
        <ordernumber>12345</ordernumber>
        <ordereditems>
            <ordereditem>
                <partnumber>smart part</partnumber>
            </ordereditem>
            <ordereditem>
                <partnumber>smart part</partnumber>
            </ordereditem>
            <ordereditem>
                <partnumber>smart part</partnumber>
            </ordereditem>
        </ordereditems>
    </order>
    <order>
        <ordernumber>ABCDE</ordernumber>
        <ordereditems>
            <ordereditem>
                <partnumber>some other stupid part</partnumber>
            </ordereditem>
            <ordereditem>
                <partnumber>smart part</partnumber>
            </ordereditem>
            <ordereditem>
                <partnumber>smart part</partnumber>
            </ordereditem>
        </ordereditems>
    </order>
</orders>

And my desired output is another xml file like this;
<orders>
	<order>
        <ordernumber>12345</ordernumber>
        <ordereditems>
            <ordereditem>
                <partnumber>smart part</partnumber>
            </ordereditem>
            <ordereditem>
                <partnumber>smart part</partnumber>
            </ordereditem>
            <ordereditem>
                <partnumber>smart part</partnumber>
            </ordereditem>
        </ordereditems>
    </order>
</orders>

The output only contains orders that do not have any ordereditems that 
have the word 'stupid' in the partnumbers. If anyone could give some 
insight as to what I need to do, or if you have any links to an article 
about using xsl in this way that is easy to understand then I would be 
very grateful.

Thanks,
J
