Ok here's my original problem. I have 166 HTML tag pages that I'm
processing one at a time. Each tag page can have 197 attributes and
potentially more arguments. Once I process the tag section of the page, I
have to address the attributes and arguments. The problem is that any given
tag page can have none or 197 attributes or anywhere in between. I needed a
method whereby I could create variables "on the fly." What I ended up doing
was taking the attribute name and appending it to an array. I then use the
name to create a series of $attxxx{$attname} where "xxx" is a unique handle
for a specific value that may or may not exist for that attribute. The name
of the variable must come from the text on the page. Once I've gathered all
of the attribute names into an array, I sort the array and begin processing
the page. How can this be done while not using soft references?
Do I make sense?
