Awk match () - multiple lines per line

I am using the match () function in gawk to grab links from an HTML file. The regex looks something like this:

match($0, /(<a href=\")([^\"]+)/, arr)

I can't seem to use the "/ g" option at the end to get a few matches per line, though?

It is right. AWK regular expressions do not have flags.
In addition, there is no built-in support for matchfinding a second or later match.
Only functions gsuband gensubhave it. I would try something like this:

gensub(/.*<a href=\"([^\"]+)/, "\1%", "g")
last = split($0, "%", arr)
delete arr[last]

where %is a string that you can guarantee will not be found in the input.
