Re: RegexTransformer - need help with regex value

[Pulkit Singhal]

Thanks a bunch, got it working with a reluctant qualifier and the use
of " as the escaped representation of double qoutes within the
regex value so that the config file doesn't crash & burn:

            <field column="imageUrl"
                   regex=".*?img src=&quot;(.*?)&quot;.*"
                   sourceColName="description"
                   />

Cheers,
- Pulkit
