Unexpected validation result when comment is present
----------------------------------------------------
Key: XERCESC-1838
URL: https://issues.apache.org/jira/browse/XERCESC-1838
Project: Xerces-C++
Issue Type: Bug
Components: Validating Parser (XML Schema)
Affects Versions: 2.7.0
Reporter: Alexey Miroshnichenko
Schema:
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema targetNamespace="http://www.openuri.org/mySchema";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns="http://www.openuri.org/mySchema"; elementFormDefault="qualified"
version="1.0">
<xsd:element name="root">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="test" type="MyType"
maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:complexType name="MyType">
<xsd:simpleContent>
<xsd:extension base="xsd:byte">
</xsd:extension>
</xsd:simpleContent>
</xsd:complexType>
</xsd:schema>
document:
<?xml version="1.0" encoding="UTF-8"?>
<p1:root xmlns:p1="http://www.openuri.org/mySchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.openuri.org/mySchema schema.xsd">
<p1:test><!-- text -->34</p1:test>
<p1:test>
<!-- text -->34</p1:test>
<p1:test>
34</p1:test>
<p1:test>34</p1:test>
<p1:test>
34
</p1:test>
</p1:root>
SAX2Print output:
<?xml version="1.0" encoding="LATIN1"?>
<p1:root xsi:schemaLocation="http://www.openuri.org/mySchema schema.xsd">
<p1:test>34</p1:test>
<p1:test> 34
Error at file Z:\eTools\bin\Debug/instance-1.xml, line 7, char 26
Message: Datatype error: Type:InvalidDatatypeValueException, Message:Value '
34' does not match re
gular expression facet '[+\-]?[0-9]+'.
</p1:test>
<p1:test>34</p1:test>
<p1:test>34</p1:test>
<p1:test>34</p1:test>
</p1:root>
Note the difference between second and third 'test' element in the document:
second has comment.
Suggested fix - in SchemaValidator::normalizeWhiteSpace function last lines:
was
if (fCurReader->isWhitespace(*(srcPtr-1)))
fTrailing = true;
else
fTrailing = false;
now
...
if (0 != *(srcPtr) && fCurReader->isWhitespace(*(srcPtr-1)))
fTrailing = true;
else
fTrailing = false;
}
Idea: isWhitespace returns 'true' for empty string, but here 'empty string'
does not mean whitepace.
Please, review.
