Did you get the latest code from cvs? or this is the code from 2.11?

Subject:[Vtd-xml-users] java.lang.ArrayIndexOutOfBoundsException:
1073741900

This is an odd issue, and I am not sure if it is a bug or I am missing
something ...

Here is what I am doing:

- Create a VTDNav instance by parsing an xml file
- Store this instance (vn) as a class variable

Method 1: isValidXml() (this function validates a section of the xml)
- I Create AutoPilot instance: new AutoPilot( vn )
- Add namespaces to ap instance
- eval xpath to navigate to an element
- get element via: getElementFragment() and then toRawString()
- add namespaces to root element via VTD-XML, but in a separate
method.

Method 2: isValidNames() (this checks element values)
- I create another AutoPilot instance: new AutoPilot( vn )
- Add namespaces to ap instance
- eval xpath to get element values ... this produces the error:

...

What I do not understand is that IF I do Method 2 before Method 1, no
issues.  My question(s) are: 
- Does getElementFragment() change or affect the original VTDNav
instance (i.e. similar to adding an attribute, element, etc... the
XMLModifier has to be 're-bound')?  
- If so, how can I refresh the VTDNav instance so I am working with
the same instance as I started?
- Does transforming that element fragment affect the VTDNav instance? 

Thank you for any help in understanding what I may be doing
incorrectly.

Re: [Vtd-xml-users] VTD Huge: Depth exceeds MAX_DEPTH

[Erik F. <eri...@un...>]

How should I reduce document size of a 1.3 GB XML file if I can’t parse it. I cannot just split it somewhere. Sure, I could do it manually (but again this wouldn’t exactly be straight forward since most editors will opt out at this file size and even vi becomes very slow and annoying to work with), but overall this should be doable with a parser.

The XML is from PubMed Central so it is not even a particular uncommon or weird piece of XML. There are some Math ML formulas in it which tend to be quite verbose. But normal, valid XML after all. So I have to fall back to StAX … :-(

The output is 33, so the depth is 32, just two more than the constant of VTDGenHuge allows us. HOWEVER I don’t know whether I don’t also have other documents with a deeper depth. Since the parser opts out already at the document with a depth of 32, I can’t say if even deeper documents would follow.

I dont think vtd-xml extended is good for that... use vtd-xml instead
and reduce document size...

 Hi again,
so I used vn.getNestingLevel() [1] to determine the maximum depth of
an element in my XML document. The output is 33, so the depth is 32,
just two more than the constant of VTDGenHuge allows us. HOWEVER I
don’t know whether I don’t also have other documents with a deeper

of 32, I can’t say if even deeper documents would follow.

 Hi there,
I was trying to parse the XML file in the attachment with the VTD Huge

fails with the error

Using VTD XML 2.11.With the normal VTD it is working because there,
the MAX_DEPTH constant is set to 254 instead of only 30 on VTD Huge.
Would it be possible to make this configurable (e.g. by a Java system

reason why this constant should absolutely stay at 30? It would make
VTD fail for my use case which would be too bad since my primary XML

Re: [Vtd-xml-users] Internal vtd-xml errors reading XML (c-sharp)

[<al...@sa...>]

We are using 2.11 on Windows, which appears to be the latest version.

The only odd thing is that we don't have a configuration where we do not get the error.
That includes 3 versions of .NET and 2 versions of Windows.

Guess we are stuck with this, so we will see if we can work around the problem by using vtd-xml to create the base xml content.
We will let you know if we can get around this issue.

Thanks,
Al Gidden

I double checked, vtdGen.parse() does not throw any errors... are you
having the latest version?

Thank you for looking into this issue. 

 The exception shows up in a debugger as an 'unmanaged' exception. 
You can tell VisualStudio to stop on these type of errors, but not
MonoDevelop. 

When I put a breakpoint on this line: 
    vtdGen.parse(false); [1] 
and Step to the next instruction you will see the error(s) in the
debugger on the stack. 

We have since tried 32-bit systems and .NET 4.0, but it does not
change anything. 
Problem is the same in VisualStudio 2012 and VisualStudio 2013, and
the current release of MonoDevelop (XamarinStudio) as well.

Subject:[Vtd-xml-users] Internal vtd-xml errors reading XML (c-sharp)

 We are trying to use C# to parse some small xml files. We have used
VTD-XML in many other languages
 and it has worked perfect for us.

 We noticed that with C# the VTD-XML parser will produce an error that
is not an exception, and then
 it will start to do odd things.

 A simple test class (Main()) is attached with an XML file that shows
the error.

 When you run the code you will see an error in the debugger (not a
thrown exception) right after
 passing line 23: vtdGen.parse(false); [1]

 This is the complete error I got from VisualStudio and the Mono
debuggers:
 Exception:Thrown: "permature EOF reached, XML document incomplete"
(com.ximpleware.EOFException) [2]
 A com.ximpleware.EOFException [3] was thrown: "permature EOF reached,
XML document incomplete"

 Just as a comparison, we can read the file in VTD-XML Java without
any errors.

 We are using the libraries from ximpleware_2.11_csharp.zip [4]. We
have .NET 4.5 and have tried Windows
 7 and Windows 8. We need to work with byte arrays to load vtd-xml.

 We have worked on this for over a week and cannot get anything to
consistently load with VTD-XML C#.
 No matter how the XML was created (ex: by hand or created from an
XmlDocument), we seem to get the
 EOF error all the time.

 We need to know what the error means and how to rectify it. Since
there is no exception, it causes a
 silent failure and poses a big problem.

 Thanks for any assistance,
 Al

	Hi,

	  

	Nowadays software security has a high degree of importance among
other things. Though this library is very good, this also need to code
pass industry standard security checks.

 The vtd-xml-2.11.jar [1] failed on Veracode security scan as these 4

	4. Yylex.java [5]                         -

	Note that java main method is an entry point and is very vulnerable
to be exploited by unscrupulous individuals.
 Test classes and methods should be handle Junit components of

	I suggest to make this library acceptable to a wider audience in the
software business, the stable release library should be free from

 To the developers of the library, please remove the main method out

 I`m looking forward for a new library release without this security

Subject:[Vtd-xml-users] Hello. New to VTD-XML and have a request

I just discovered the VTD-XML project and am very intrigued.  The use
case I have is that I'm pulling messages off a queue and I want to
feed them into an XML parser as bytes or UTF-8 string.
However, all the parse methods in VTDGen accept filenames, other than
the parse(boolean) method, which I don't understand how to use.
My request is to add a parse(InputStream) method (or possibly even a
parse(ByteBuffer) method), since I can pass the bytes in as a
ByteArrayInputStream.  I am interested in the Java API.
The parse(InputStream) method would be simple enough that I could even
do a code patch and submit it if that works for you.
Thank you,Michael

Re: [Vtd-xml-users] Hello. New to VTD-XML and have a request

[<jz...@xi...>]

dump the xml into an input buffer and feed it to vtdGen... this is how
vtd-xml is designed to work...let me  know if you need more
explanation...Jimmy

Subject:[Vtd-xml-users] Hello. New to VTD-XML and have a request

I just discovered the VTD-XML project and am very intrigued.  The use
case I have is that I'm pulling messages off a queue and I want to
feed them into an XML parser as bytes or UTF-8 string.
However, all the parse methods in VTDGen accept filenames, other than
the parse(boolean) method, which I don't understand how to use.
My request is to add a parse(InputStream) method (or possibly even a
parse(ByteBuffer) method), since I can pass the bytes in as a
ByteArrayInputStream.  I am interested in the Java API.
The parse(InputStream) method would be simple enough that I could even
do a code patch and submit it if that works for you.
Thank you,Michael

Re: [Vtd-xml-users] VTDNav.toElement Not Moving To Siblings

Please disregard. This turned out to be a bug with the complex way I was
using VTD, rather than a bug with VTD itself.

Re: [Vtd-xml-users] VTDNav.toElement Not Moving To Siblings

[Tom D. <tom...@gm...>]

Specifically, I am trying to traverse the element tree recursively. I'm
wondering if coming back to the parent causes the VTDNav to lose track of
what the next sibling should be?

RecursiveProcessing(n):
go to first child
  for child c
    RecursiveProcessing(c)
    go to next sibling
go to parent
