Hi, Steve,
Yep, it's a start. Some problems (output below), but I think it will
get me a little farther.
And you're right, I already gave up on getting everything in one pass.
I was thinking of trying to just get everything for a single element
type (i.e. all <input type=text ...> elements), but this gives me
another idea, also.
And the output from the first try:
Array
(
[0] => Array
(
[0] => <select n
[1] => <select n
[2] => <select n
)
[1] => Array
(
[0] => select n
[1] => select n
[2] => select n
)
[2] => Array
(
[0] =>
[1] =>
[2] =>
)
[3] => Array
(
[0] =>
[1] =>
[2] =>
)
[4] => Array
(
[0] =>
[1] =>
[2] =>
)
)
