Hi Charles,
Yes your understanding of my requirement is right, this is what I am looking
for except for > that, (x) is not any sequential number but the value of the
<SeqNumber>(which is always > sequential). I have tried your previous
solutions where you had suggested to use the
following rule
<xsl:for-each select="Risk[(_at_)RepeatDet]">
This worked for me in the sense that, it does match only those <Risk> nodes
which has
<RepeatDet> attribute but there is one problem. It is going through the
for-each loop as
many times as there are <Risk> nodes with <RepeatDet> attributes, I mean, if
there are 3 > <Risk> nodes with RepeatDet attributes, it iterating through
the look 9 times and I have
ExistingProductType, ExistingPolNumber....... .etc. 9 times instead of just 3
times. What
could be the reason?
There are two reasons:
1) You have written the for-each loop incorrectly
2) You shouldn't be using a for-each loop in the first place
We'll chalk up reason #2 to the fact that you are used to programming in a
procedural language (i.e., Java). You will find XSL much easier if you let the
processor work out the details of how to get things done. In this way, XSL is
like SQL. You tell the database engine what you want and let the DBMS figure
out the best way to get it. You wouldn't try to retrieve data from a database
by writing a program to open two tables inside nested for-each loops and pull
out data with matching columns. You would simply tell the database
SELECT FROM tbl_1 where tbl_1.SSN = tbl_2.SSN;
in order to pull all the rows from tbl_1 that have a value in the SSN column
that matches a row in tbl_2 with the same value in the SSN column.
Given that, here is a stylesheet that does what you want. Before I give it to
you though, there are a couple of things to point out.
1) <XML> is not a legal element name as "XML" is reserved. I changed your
document element name to "doc" to clear this up.
2) I couldn't figure out why you put the xmlns="" attribute in each <field>
element, so I left it out. If there is a good reason for having it there, I'm
sure you'll figure out how to get it back.
3) I don't see the point of having a <value> child node inside each <field>
element (although I left it there). Wouldn't your life be simpler if you
eliminated the <value> element altogether and put its value in the <field>
element?
