Jmeter中的正则表达式提取器

Question

I have this response in HTTP request as below

href="index.php?module=Meetings&action=DetailView&record=ed51c2d9-1958-bd61-cce1-509d30ccd4ac">

I want to get the value of "record", but when I set

Regular Expression : record=(.+?)

only "e" is returned. What do I need to do instead?

Answer 1

Well the regular expression consumes as little as possible (due to the ? ). Hence, it is satisfied after taking in the first character. You should probably rather make it greedy and restrict the possible characters (so that it cannot go past the end of the parameter):

record=([a-f0-9-]+)

If you do not know which characters are allowed as the parameter's value, you could also say, consume everything but ampersands and quotes:

record=([^"'&]+)

Depending on where you use it, you might need to escape one of the quotes with a backslash.

Answer 2

The given text

href="index.php?module=Meetings&action=DetailView&record=ed51c2d9-1958-bd61-cce1-509d30ccd4ac">

Regular Expression to get the record values from the given text values

record=(.+)"

Regular Expression gets the following record values

record=ed51c2d9-1958-bd61-cce1-509d30ccd4ac"
