Re: HTML::TableExtract - Easy Way To Tell If It Found A Table?

"I'm really struggling with ..."

I don't think pasting the first block of code that appears in the SYNOPSIS of the HTML::TableExtract documentation really involves any particular effort. It certainly doesn't equate to struggling!

You're going to need to read and understand the documentation. Blindly copying code, and expecting it to perform whatever task you're thinking of, isn't going to work.

The truth of

scalar $te->tables
[download]

will tell you whether any tables were found using the supplied headers criteria.

You'll need to explain what you mean by "any legitimate tables". Possibly, the truth of

scalar @{($te->tables)[0]->rows}
[download]

is what you want.

So basically, I could just do an if statement like: `if ($te->tables) { print "I found a table!"; }` [download] And something as simple as that would tell me if it found a table (as long as I called the parse function first)? I love it when a program comes together - jdhannibal	[reply] [d/l]

"So basically, I could just do ..." Yes. Instead of typing the code into a forum, you could type it into your program. You could then run the program and find out what happens all by yourself. -- Ken	[reply]
