Re: [Pharo-users] PetitParser question

Hi Doru, Thanks for pointing out the use case in XML, which gave me an opportunity to play around with this with almost no effort. Unfortunately there seems to be a bug in how PPXmlParser constructs the PPFailure message (freshly reported: https://github.com/moosetechnology/PetitParser/issues/38).

Re: [Pharo-users] PetitParser question

Hi Konrad, A somewhat similar issue is present in an XML grammar: the closing element must match the opening element. In PPXmlGrammar, you have a condition that matches it and throws a failure otherwise: element "[39] element::= EmptyElemTag | STag content ETag"

Re: [Pharo-users] PetitParser question

Dear Tomo, This post might help you. In case of PetitParser2, it's PP2Failure instead of PPFailure. https://stackoverflow.com/questions/15371334/how-can-a-petitparser-parse-rule-signal-an-error That's indeed a possible solution: parse for arbitrary operators, and then add a test for equality

Dear parsing experts, I have been working on a medium-size parser using the PetitParser framework, which so far has been a very productive environment. But now I have a problem to which I could not find the solution in "Deep into Pharo", nor by searching around in the code. One of my production

This is kind of a "I'm tired of thinking about this and not making much progress for the amount of time I'm putting in question" but here it is: I'm trying to parse descriptions from HTML meta elements. I can't use Soup because there isn't a working GemStone port. I've got it to work with
