Parser hanging when large number of optional elements
Summary: Parser hanging when large number of optional elements
Product: Xerces2-J
Version: 2.0.1
Platform: Sun
OS/Version: Solaris
Status: NEW
Severity: Normal
Priority: Other
Component: JAXP
AssignedTo: xerces-j-dev@xml.apache.org
ReportedBy: home@andrewjasper.plus.com
When validating an XML message against a DTD the parser hangs and the CPU usage
reaches 100%.
I've tried with both the Crimson and Xerces, DOM and SAX parsers.
I have a large number of optional elements in my DTD.
The XML and DTD and Java are attached.
I've tested this on Windows 2000, and Solaris 2.8.
When I increase the number of optional elements in one group element above 52
the time taken to parse the XML starts to increase exponentially.
To the point where I have 60 optional elements it takes in excess of 15 seconds
to parse one message.
At 50 optional elements there is no problem. Above 60 optional elements I
might as well be hand writting the message out.
I know a solution is to split the optional elements between a number of group
elements, as I've tried it - I have 50 optional elements in one group element
and the remaining 25 in another group element, LINE_GENERAL_1 and
LINE_GENERAL_2.
The other solution would be to switch validation off - which I don't want to do.
Thank you
Andrew
