RHBA-2011:1446 - Bug Fix Advisory

Topic

An updated perl-XML-SAX package that fixes various bugs is now available for Red
Hat Enterprise Linux 5.

Description

XML::SAX is a SAX parser access API for Perl. It includes classes and APIs
required for implementing SAX drivers, along with a factory class for returning
any SAX parser installed on the user's system.

This updated perl-XML-SAX package includes fixes for the following bugs:

• Parsing a long XML document with the XML::Simple API took an unacceptably long

time if the XML::SAX parser implementation was available. The XML::SAX parser
implementation was not optimized for large string variables (e.g. 2 MB). The
XML::SAX parser has been updated to handle the reading of large strings in a
more efficient way. This update enables long XML documents to be parsed in a
more reasonable time. (BZ#641735)

• XML documents which have a whitespace character as the first character were

not handled correctly. A warning, "Unable to recognize encoding of this
document", was printed. With this update, encoding detection code has been
changed to recognize XML documents with leading whitespace as a document without
an XML declaration and with a default encoding. The warning is no longer printed
as such documents are valid documents with encoding detection rules conforming
to documents without an XML declaration. (BZ#744200)

All users of perl-XML-SAX are advised to upgrade to this updated package, which
resolves these bugs.
