Lets say I’m processing products that can have multiple types of a certain node
distinguished by value, of which I want only one in my result, and I have a
precedence order by type of those nodes that shoudl determine which one I get.
So, if the child of product I’m interested in is price currency and my product
had
<product>
….
<price>
<amount>25.00</amount>
<currency>FR</currency>
</price>
<price>
<amount>20.00</amount>
<currency>US</currency>
</price>
<price>
<amount>30.00</amount>
<currency>CA</currency>
</price>
</product>
And my preference is to take the only one price in the order 1., US, 2. CA,
3.FR.
In context product, if I say
<xsl:apply-templates
select=“(price[currency=‘US’],price[currency=‘CA’],price[currency=‘FR’])[1]”/>
I get the FR price because it’s first in doc order, but my expression was meant
to say process nodes in this sequence order, taking the first one, in the
sequence, not in the doc order of the input tree.
I thought the above instruction would be a short cut to achieving this, but it
doesn’t work. Is there a concise way to express the kind of precedence I want?
Thanks.
