[XERCESC-1620] whitespace lost in schema validation

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: 2.7.0
• Component/s: SAX/SAX2
• Environment: Windows 2000 SP4; Visual Studio .NET 2003
• Assignee: Unassigned

Description

When XMLSchema validation is enabled, some whitespaces are reported neither characters() nor ignorableWhitespace() event.

Following is output of sample program which is attached below.

<characters>1234 5678 1234 5678 1234 5678 1234 5678</characters>
<characters> 1234 5678 1234 5678 1234 5678 1234 5678 1234 5678</characters>
<characters>1234 5678 1234 5678 1234 5678 1234 5678</characters>
<characters> 1234 5678</characters>

Between the 2nd and 3rd characters() event, whitespace is lost.

Is it distinguishable the last token of 2nd event and first token of 3rd event are differenet words or parts of continuous word?

Regards,

Takashi Matsuda.
