Invalid IDREF attribute error

Hello!

I'm using Xercces-J 2.9.1.

I tried to validate the XML document that have two invalid IDREF type
attribute 'xref' elements.

 <para>This is a test.<xref linkend="aaa"/><xref linkend="bbb"/></para>

But Xeces reports only one error.

 'An element with the identifier "bbb" must appear in the document.'

Why Xerces does not report all of the unresolved IDREFs? Is this the
limitation?

Any suggestions are welcome.

Thanks,

Toshihiko Makita

Re: Regarding XML Schema on Linux

Look into using an EntityResolver [1].  Your schemaLocation points to a URL that 
doesn't resolve.  You need to map that URL to a local resource.  That's what the 
EntityResolver is for.

error check in sample SAXWriter

Hello Xercianer,

I have to validate a XML file against a XSD and tried the java version 
of xerces for this task.
I simply installed Xerces (2.8) and the sample-jar  and called

java sax.Writer -v -f -s foo.xml 1>/dev/null | grep Error

I'm not interested in the output. Because I'm on Unix I redirect
the output to /dev/null and I grep  stderr for "Error" to detect
all kind of errors. If the return code of grep is 0 then the XML file
is not valid.

My questions: 
1. Is there a better java-xerces "tool" for doing that task
    (something like xmllint in java) ?
    (I missed the possibility to suppress the output via a command line
     switch.)
2. Is it reliable to grep for Error in stderr ? Are there situations there no
    Error-line is printed but the XML is still corrupt ?
    (The C++ version of Xerces comes with samples too and when I call
     SAX2Print ... I'm able to detect validation/parse errors via the return code
     of the program. This seems not the case with the java version.)

Best regards,
Thomas

Re: complexType with simpleContent facet violation message not helpful

Hi Ron,

We weren't assigning an anonymous type name to the simple type. I just
committed a fix for that. If you pickup the current code from SVN you
should get "#AnonType_Comment2Type" instead of "null" as the type name in
the error message.

Thanks.

Re: Invalid IDREF attribute error

Hi Toshihiko,

This is currently a limitation. The class Xerces uses for checking ID/IDREF
is only capable of returning the first IDREF found without a matching ID
value.

Re: error check in sample SAXWriter

Hi Thomas,

The sample registers an ErrorHandler which prints every error reported to
it to System.err; each line prefixed with "[Fatal Error]", "[Error]" or
"[Warning]". If you grep for those you should catch every error / warning
emitted by the parser. The regular output from the sample is written to
System.out. You cannot suppress it unless you wrap your own program around
it which redirects the output elsewhere. There's no command line switch for
that.

Thanks.

Re: jar conflict causing java.lang.VerifyError

Hi,

There's no release of Xerces which has both of those classes. Looks like
you have copies of Xerces-J 1.x and 2.x on your classpath so it wouldn't
surprise me if you ran into compatibility problems. Try replacing whatever
jars you're using with the latest release [1].

Thanks.
