RE: [xsl] Grouping into a table (for vertical alignment)

["Daniel Joshua" <daniel.joshua@xxxxxxxxxxxx>]

Wendell,

I choose a simple example (login page) to post this question. But other
pages are more complex. The output is meant for Browsers to transform client
side

Currently the input XML structure has a <form> tag which can have either:

 1) "presentation tags" like <text>, <image>, etc which require to fill the
whole width (in the HTML, these are already placed in <div> to get its own
line WITHOUT any <table>)

 2) "entry tags" like <input>, <password>, <checkbox>, etc which require to
be separated into a label and a value (in HTML, I want these to be placed in
a <table>, EITHER a new table if the previous tag was a "presentation tag"
OR a new row in the previous table if the previous tag was an "entry tag")


The special considerations for this are:

 A) there can be any sequence of "presentation tags" and "entry tags"

 B) if there are "presentation tags" in-between groups of "entry tags", then
each separated group of entry tags will have their own table.

 C) I do _not_ want to put "presentation tags" in a table in anyway (eg. use
a single column with "colspan=2")


As for why is my output XHTML, it doesn't really matter to this question...
let's just treat the output as HTML.


Regards,
Daniel

Daniel,

What assumptions, if any, can we make about the proximity of <input> and
<password> elements? Can either appear independently of the other? Can
arbitrary <text> elements appear between them at any point? How many can
there be? (You've indicated that more than one <input> can appear, but not
said whether none can appear, or whether there will always be a <password>,
or how many <password> elements there could be.)

These are relevant since the solution will be to produce one or more tables
in a template matching <content> or perhaps a template matching <input> or
<password> (which would then pick up certain of the matching element's
siblings to tuck them into the table), but this raises the question of how
and whether <text>, <input> and <password> elements should be grouped
together in a table. The precise logic to do this will be easier to
determine if we know what kinds of constraints operate over the input.

If you have a content model for your <content> element (from a DTD or
schema), this would be a big help.

Cheers,
Wendell
