The problem I have is basically this:
I am using an <xsl:key/> that accepts an id attribute as a parameter. So
when I use the key function I usually call it as: key(accountName, @id),
which retrieves the element from the match xpath expression, with the
specified id attribute. This I can do.
I would now like to pass the value of the id-attribute from the
following-sibling (not the current node) into the function. But I don't
know how to retrieve this attribute value so that I can pass it into the key
function. Perhaps there is another way to avoid this problem?
Here is a snippet from my XSL that illustrates the problem:
<xsl:key name="TotalRevenue" match="Stock/Account[(_at_)label='TotalRevenue' and
@period='Quarterly']/Item" use="@id"/>
<xsl:key name="ExpenseOne" match="Stock/Account[(_at_)label='ExpenseOne' and
@period='Quarterly']/Item" use="@id"/>
<xsl:key name="ExpenseTwo" match="Stock/Account[(_at_)label='ExpenseTwo' and
@period='Quarterly']/Item" use="@id"/>
....
<xsl:for-each select="Account[(_at_)label='TotalRevenue' and
@period='Quarterly']/Item">
<xsl:value-of select='format-number( (key("TotalRevenue",@id) -
following-sibling::*[1],"#0.0%;(#0.0%)")' />
</xsl:for-each>
This works fine. I look through the Items in the TotalRevenue account, and
for each Item I subtract the value of the next item in the TotalRevenue
account. But now I still want to loop through the items in the TotalRevenue
account, but I ALSO want to subtract the value of the next Item in this
account AND the values of the items in the ExpenseOne and ExpenseTwo
accounts which have the SAME id (the id of the following-sibling, not the
node selected in the for-each, in the TotalRevenue account).
Ideas?
Any help would be much, much appreciated.
