Re^2: extract ids

Hi, Thanks a lot for answering my doubts. I would like to know how

/molecule_idref="([^"]+)/
[download]

will match everything between the quotes. I didn't understand why "([^"]+)will match anything between the quotes. Thanks.

`[^"]` [download] in a regex means: everything BUT a double quote. `"([^"]+)` [download] therefore means: start with a double quote, then capture everything but a double quote and end the capture. In other words, the capture starts after the first double quote and ends just before the next double quote.
