[jira] Created: (XERCESJ-1357) pattern causes the parser to hang
pattern causes the parser to hang
---------------------------------
Key: XERCESJ-1357
URL: https://issues.apache.org/jira/browse/XERCESJ-1357
Project: Xerces2-J
Issue Type: Bug
Components: SAX
Affects Versions: 2.9.1
Environment: Windows XP
Reporter: Navaneet Kumar
Priority: Critical
I have a pattern in my Schema:
<xsd:simpleType name="ElsterString">
<xsd:annotation>
<xsd:documentation> Alphanumeric and ".", "-", "_".
</xsd:documentation>
</xsd:annotation>
<xsd:restriction base="xsd:string">
<xsd:pattern value="(([A-Za-z0-9]|\-|\.|_)+(( )*([A-Za-z0-9]|\-|\.|_)+)*)?"/>
</xsd:restriction>
</xsd:simpleType>
Th pattern is trying to force this rule:
no characters other than letters and numbers and -, . and _. And no white spaces at the end. White space is allowed in the middle.
When I try and parse it against a document, the parser hangs some times. Longer strings appear to cause the hang more frequently.
I was validating this string:
Name="aPipeTest_LANPerformance sksksk sksksk sksksk "
This string caused the parser to hang. I can use longer strings and get the parser to hang at will.

Description:
I have a pattern in my Schema:
<xsd:simpleType name="ElsterString">
<xsd:annotation>
<xsd:documentation> Alphanumeric and ".", "-", "_".
</xsd:documentation>
</xsd:annotation>
<xsd:restriction base="xsd:string">
<xsd:pattern value="(([A-Za-z0-9]|\-|\.|_)+(( )*([A-Za-z0-9]|\-|\.|_)+)*)?"/>
</xsd:restriction>
</xsd:simpleType>
Th pattern is trying to force this rule:
no characters other than letters and numbers and -, . and _. And no white spaces at the ends. White space is allowed in the middle.
When I try and parse it against a document, the parser hangs some times. Longer strings appear to cause the hang more frequently.
I was validating this string (it has a space in the end which is not allowed by the pattern)
Name="aPipeTest_LANPerformance sksksk sksksk sksksk "
This string caused the parser to hang. I can use longer strings and get the parser to hang at will.
