Subject [jira] Updated: (AXIS2C-859) guththila parser fails to handle escape sequences for ampersand, less than, greater than
Date Tue, 29 Jan 2008 10:05:34 GMT


Lahiru Gunathilake updated AXIS2C-859:

    Attachment: diff.txt

Now guththila parses escape charactor.Please go through the patch file and apply this since
this may reduce the performance of Guththila parser.

> When an incoming message contains within text the escaped ampersand sequence, "&amp;",
this sequence is being passed to the client as raw text without being converted to the single
ampersand character.  Clearly, this action must take place at the level of the parser, as
only the parser knows whether it is seeing simple text, and conversion is required, or text
embedded in a CDATA section, where conversion is not allowed.  I have tested the build with
the libxml parser, and of course the libxml parser behaves correctly: the text passed to the
client contains only the single ampersand character, not the escaped sequence.  (See section
2.4 of XML 1.0 spec.)
> Looking at the code, I expect the same problem occurs with all escaped sequences, less
than and greater than as well as ampersand, on both input and output.  I also don't see where
CDATA sections are handled, but as I am not seeing CDATA in the messages from the service
I am hitting, I have not tested this case.
