Re: [xsl] Using xsl:iterate inside <xsl:for-each-group> xslt 3.0

["Terry Ofner tdofner@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Wow. That is certainly efficient. I can see that I have some catching up to
do. I am not familiar with as=map() and the call of it.

I am looking now at the version using iterate. So, the sequence inside $groups
looks something like this:

bletterb : <span class=bletterb>S</span> : btermb : <span
class=btermb>sentence</span>


Similar in construction to JSON?

I am also unfamiliar with the use of the exclamation point in <xsl:iterate
select="p[@class = 'nl'] ! $groupsb>

Similarly, the question mark in the population of the attributes is new to me"
letter="{?letter}b.

I get a vague sense of how this works. More reading is in store. For sure.

Thanks.
