Regular expressions again...

I am using Scripted Assertions that use regular expressions. I.e. the Groovy code ends up in a statement like: assert response =~ pattern   In about 100 test-cases this works brilliantly but with...

Do you want to show the response and pattern that you were trying and they are failing? That would help to understand the issue.

 

By the way, this link should help to improve the understanding of regex in groovy.

Sure - no problem:

 

The regexp reads e.g.:

<AirlineResource>
\s*<Airlines>
(\s*<Airline>
(\s*<OtherIDs>
(\s*<OtherID Description="Short Name">.*</OtherID>
)*\s*</OtherIDs>
)?\s*<AirlineID>\w{2}</AirlineID>
(\s*<AirlineID_ICAO>(\\N|\w{3})</AirlineID_ICAO>
)?\s*<Names>
(\s*<Name LanguageCode="\S{2}">.+</Name>
)+\s*</Names>
\s*</Airline>
)*\s*</Airlines>
\s*<Meta Version="1\.0\.0">
\s*<Link Href="https://52\.58\.16\.38:9895/references_v1\.1\.0/airlines(\?lang=DE)?" Rel="self"/>
\s*<Link Href="https://52\.58\.16\.38:9895/references_v1\.1\.0/airlines/\{airlineCode\}(\?lang=DE)?" Rel="related"/>
\s*</Meta>
</AirlineResource>

The captured response I attach as file.

 

 

I also attach two screenshots of RegExBuddy in action, the first showing the above entered into the RegEx-field (top) and the response (bottom area). The yellow background color indicates a match.

The second screenshot shows the result of the "tracing", i.e. one can see the misc. matching steps and the backtracking.

At the bottom you see that a full match was found after 2565 steps.

 

But - as I said: when the same is compared within soapUI I get a popup:

Error

An error occured  ...

 

From the log I capture the following:

Does that give you any indication what's going wrong here and how to possibly avoid that?
