simple query regarding the count function

Apologies if this has been asked before, but I am struggling a bit with
what I think should be a fairly straight forward piece of logic.

In xsl speak I want to count a number of elements based on 2 different
children having conditions that must be met to take part in the count.

According to my actual business example what I want to do is count the
number of requirement elements that have a child element of
ldor_requirement_ifa set to Y and tanother child element that has to have a
requirement code of A21C, A50A or ?OTHR. The result from the count can only
ever be 0,1,2,3

I thought this would be quite simple to acheive but I keep running into an
issue when the query within the result set returns a boolean result which
then returns an error. If I remove everything apart from one test, the
count will evaluate the condition as expected but obviously this is not
what I require. I've gotten close by adding count conditions for each
requirement code but I can't integrate the test on the ifa node into this
condition.

If anyone is helpful enough to answer my query I would be most grateful.
Some things that you have to aware of, I'm not using templates, apart from
one match condition of root at the beginning of the template. So any
suggestion involving templates is not going to work unless I drastically
rewrite the stylesheet which I don't want to do. I'm also not able to
change the structure of the xml.

Thanks, Simon Demler


Code snippets below:


XSL query

xsl:value-ofselect="
count(/header/policy/requirement[ldor_requirement_ifa='Y'] and

/header/policy/requirement[ldor_requirement_code='A21C'] or

/header/policy/requirement[ldor_requirement_code='A50A'] or

/header/policy/requirement[ldor_requirement_code='OTHR'] )"/>

this works but doesn't include the ifa requirement condition I need.

xsl:value-of select="count(/header/policy/requirement[ldor_requirement_code
='A21C']) +

count(/header/policy/requirement[ldor_requirement_code='A50A']) +

count(/header/policy/requirement[ldor_requirement_code='OTHR'])"/>
