Hello everybody, I found a bug while playing with the XMLPullParser: When using XML entities encoded in hexadecimal the parser throws an exception. For example: is the hexadecimal encoding of which is the line feed. If you try to parse: '<tag contents="one two" />' you get a "Expected Number" error. I investigated the problem, and found that it is caused by the method XMLPullParser>>readNumberBase: If the base of the parsed number is not 10, it executes the following lines: numberString := self nextUpTo: $;. self stream skip: -1. [...] However, the method nextUpTo: does not exist. A MNU is then raised and handled in nextCharReference: by a greedy "on: Error do: [:ex | self errorExpected: 'Number.']." thus causing the exception. The solution is either to implement nextUpTo: or to change it in one of the two existing methods: nextUpToAll: or nextTrimmedBlanksUpTo: Example: numberString := self nextUpToAll: ';'. Also, in the following line, it calls the accessor "stream", which does not exist and causes the same problem. The solution here is to change self stream skip: -1. into stream skip: -1. The following two test cases show the problem. The first one shows the correct behavior: XMLPullParserTest>>testASCIIEntity | parser | parser := XMLPullParser parse: ' <tag contents="one two" />'. self assert: (parser next at: #contents) equals: (Character lf join: #(one two)) The second one shows the error: XMLPullParserTest>>testUnicodeEntity | parser | parser := XMLPullParser parse: ' <tag contents="one two" />'. self assert: (parser next at: #contents) equals: (Character lf join: #(one two)) I hope it is clear enough. I can also commit the fix myself, if you give me write access. Thanks, Tommaso
