Exiting from SAX parser on finding specific element/attribute

Is there a way to return/exit from a SAX parser as soon as I get my search element the first time, without parsing the whole XML file?
Please let me know.
Thanks

Thanks for the information, but what I am exactly looking for is to only return back from SAX parser to the calling program.
System.exit(0) shuts down the whole application.
please let me know

How to retrieve version and encoding info from SAX parser

I want to have access to the version and encoding info in a parsed XML document (when using SAX2). Who knows how this works?
If not possible with SAX2, what other solutions are there?
Second question: how to retrieve comments in XML files?
Thanks in advance!

thanks for answering, but ...
LexicalHandler is fine for retrieving the comments,
but does not give me the encoding (specified by
encoding="UTF-8") and version (specified by
version="1.0").
I am feeding my parser with a byte stream, the parser
resolves the correct encoding and i want to have
access to this value!!hi , It is unlikely that you will get the encoding and version . This is being addressed by the DOM level3
, see

SAX parser not finding my DTD. Help please

I have written a small XML file and its DTD that are stored in the same folder which is C:/Work/pdftools. Here is a part of the code that is generating errors:
inputSource.setSystemId( "c:/Work/pdftools/userSettings.xml" );
parserAdapter.parse( inputSource );
So, I am setting the systemID on my inputSource that I want to parse.
But, i am encountering the following error:
"External entity not found: "c:/Work/pdftools/userSettings.dtd"
Does someone have any idea why is this happening?
Thanks

"c:/Work/pdftools/userSettings.dtd"Because that isn't a URL. Tryfile://c:/Work/pdftools/userSettings.xmlor something like that with 1 or 3 slashes after "file:".

Need to find specific OD attributes for an new application.

I have an application that supports LDAP v3 and is requesting the following info. I need to know what the valuse are for these in Apple's Open directory or how to find them on the directory server.
I'm used to setting this app up in a Novell environment and it works great, the company says it will work with Apple's OD but doesn't support it through their tech support.
LDAP Base DN
LDAP UID Attribute
LDAP Group Attribute
It also has a spot for a username and password if needed to authenticate to the directory. Can anyone tell me if this is necessary, and if so can I just use any account or does it have to be a directory admin account.
Thanks in advance for any help you can provide.

Unless i insert at the right place in muse (like in a master page) the menu module tag generated by BC right?
and for some obscure reason, i'm having a F*$*ing hard time to style
this will need to be possible in Muse future, i know muse grid came with a BC blog Module, hopefully they will come up with a BC dynamic menu module.
(sigh) ... i'm so discouraged

SAX parsing to return element instead of document

Hi,
Is there any sample implementation which would allow my SAX parser to return just Element object instead of returning the whole document.
Thanks for your help.

How to select specific element from a XML document using JDBC?

Hi all,
I have a problem with selecting specific XML element in Oracle 11g release 1 from my java application. Data are stored in object-relational storage.
My file looks like:
<students>
<student id="1">
</student>
<student id="2">
</student>
<student id="3">
</student>
</students>
I need to select a specific <student> element. I've already tried few ways to achieve my goal but I failed.
SELECT extract(OBJECT_VALUE,'/students/student') FROM students - works fine, but this selects all <student> elements
SELECT extract(OBJECT_VALUE,'/students/student[1]') FROM students - which should select first <student> element works too but it causes exception when using JDBC driver returns:
java.sql.SQLException: Only LOB or String Storage is supported in Thin XMLType
     at oracle.xdb.XMLType.processThin(XMLType.java:2817)

     at cz.zcu.hruby.data.Select.getStudent(Select.java:45)
SELECT to_clob(extract(OBJECT_VALUE,'/students/student[1]')) FROM students - in this case I hoped that DB would convert result to CLOB but the element is quite large (definitely more than 4000 Bytes long which I find out from forum is limit). But this exception occurs:

This behaviour raises two questions:
1) Why SELECT extract(OBJECT_VALUE,'/students/student') FROM students works but SELECT extract(OBJECT_VALUE,'/students/student[1]') FROM students does't ?
2) Is there any way how I can select specific element (element XPath /students/student[@id="some value"]) and convert it to String?
Thanks for your responses I would appreciate any suggestion
Honza

To be exact my <student> element is a bit complicated and looks like the one at the end of this post (sorry but it's in czech). And I need to select whole xml fragment (all opening and closing tags included) as it is shown. Maybe I used wrong solution and I should use CLOB storage. I discuss this issue here: Which solution for better perfomance?
Thanks anyway for your response. I would be very grateful if you have any further idea

Problem reading ' from XML uisng SAX Parser

Hi All,
I have a XML which contains the following element
<DataText>This is simple ' Text</DataText>I have included & apos ; in the element called DataText.
When parsing the element, am getting only the text that appears before & apos ;
When Not including & apos ; am able to get the full text from this element.
I observed that in the method characters(char buf[], int offset, int len)
Thelen attribute shows the total length from start position to the position where & apos ; starts...
How can i get the whole text which includes even " & apos ; "
Thanks
Note : while posting this request, & apos; is being formatted to ' . thats the reason included space between them

HI,
Was not doing much in the characters method, anyway here is the code
public void characters(char buf[], int offset, int len) throws SAXException{
elementText = new String(buf, offset, len).trim();
}The value for len is from the start position of the element value and the start position of the ' & apos; ' in the XML File...
If i remove the ' & apos; ' in the element value , then the len is the full character length in between the element.
Very confused why this is happening !!
Did anyone face this problem ever before ?

Using xs:all element and the Weblogic provided SAX Parser

I am trying to validate XML documents against an xsd schema which has within it
the xs:all element to indicate that certain elements should be present but the
order in which they appear is not important. I have found that when I try to parse
a document against this schema using the SAXParser that is provided with Weblogic
the xs:all element seems not to be supported.
Has anybody else experienced this?
I have tried the same code but using a different SAX Parser (Apache provided)
and this no longer seems to be a problem.
Any advice would be appreciated.

Hi Jonathan,
I took a quick look through our problem reports and did not see anything
related to this issue. Is this with WLS 8.1SP1? I'd suggest creating a
small reproducer and open a case with our award winning support group:
http://support.bea.com or [email protected]
Thanks,
Bruce

Efficient searching in a large XML file for specific elements

Hi
How can I search in a large XML file for a specific element efficiently (fast and memory savvy?) I have a large (approximately 32MB with about 140,000 main elements) XML file and I have to search through it for specific elements. What stable and production-ready open source tools are available for such tasks? I think PDOM is a solution but I can't find any well-known and stable implementations on the web.
Thanks in advance,
Behrang Saeedzadeh.

The problem with DOM parsers is that the whole document needs to be parsed!
So with large documents this uses up a lot of memory.
I suggest you look at sometthing like a pull parser (Piccolo or MPX1) which is a fast parser that is program driven and not event driven like SAX. This has the advantage of not needing to remember your state between events.
I have used Piccolo to extract events from large xml based log files.

Bug in Excel's handling of metadata? Or at least a deviation from the Open Office XML specification?

I've discovered some very strange behaviour in Excel which seems to be contrary to that documented in the Open Office XML specification (OOXML). I couldn't find a way to report bugs against Excel, so I thought I'd try to explain the issue here.
In short it seems that Excel is removing, and incorrectly re-indexing the metadata I programatically associate with cells.
First, a summary of the relevant parts of the specification:
From OOXML 18.9: There are two types of metadata: "cell metadata" and "value metadata".
Cell metadata follows the cell as it moves. Value metadata follows the value through formulae etc.
From OOXML 18.3.1.4: The c (cell) element has cm and vm attributes which are both documented as "The zero-based index of the [cell|value] metadata...in the Metadata Part"
From OOXML 18.9.17: The valueMetadata is "a collection of block element that each define the value metadata for a particular cell". "Cells in the workbook index into this collection".
The valueMetadata contains bk elements which in turn contain rc (metadata record) elements
From OOXML 18.9.15: rc elements have t (type index) and v (value index) attributes. t is a 1-based index into metadataTypes and v is a 0-based index into the futureMetadata element which matches the name of the metadata type.
Here's an example of what this might look like:
<c vm="0"> 
<x:valueMetadata>
<x:bk>
<x:rc t="1" v="0" /> 
</x:bk>
</x:valueMetadata>
<x:metadataTypes>
<x:metadataType name="MyMetaType" ... /> 
</x:metadataTypes>
<x:futureMetadata name="MyMetaType" ...>
<x:bk>
<x:extLst>
<x:ext xmlns:x="http://schemas.openxmlformats.org/spreadsheetml/2006/main" uri="http://example.com/extension" p5:value="test value" xmlns:p5="http://example.com/extension" />
</x:extLst>
</x:bk>
</x:futureMetadata>
The Problem
From what I can tell, for values of n > 2, if you associate n cells with metadata, Excel will drop the last piece of metadata, and the one at index 1, and it will do so silently. The indices are then 0..n-3, and the association for all but the first (0
index) will be wrong. This renders the future metadata totally useless.
For n == 1, Excel just removes the last piece of metadata (index 1). If we try 1-based indexes for the vm attribute on the c element, we get different behaviour. This may not be relevant as it is contrary to the specification, but the slightly better behaviour
might indicate an off-by-one error:
n
Deleted Indices (0-based) when using 0-based indices
Deleted Indices (0-based) when using 1-based indices
1
0
None
2
1
1
3
1,2
1
4
1,3
1
5
1,4
1
6
1,5
1
Demonstrating the Problem
I have some example code[1] that demonstrates the problem. You will need a file called test.xlsx with cells A1..C2 populated.
Compile the source as AddMetadata.exe then run with the test file as the only parameter:
> AddMetadata.exe test.xlsx
You can look at test.xlsx in Excel, Visual Studio (with the Open XML Package Editor Power Tool for Visual Studio 2010) or the Open XML SDK 2.0 Productivity Tool for Microsoft Office. Looking at the file before and after running AddMetadata.exe you should
be able to reproduce the behaviour documented above.
Summary
It would be good to know if this is really an Excel bug or whether we're doing something wrong / unsupported. Any insight would be very much appreciated.

If you create a metadatatype with a single metdata block, and you reference that in your vm/cm cell attribute using a *one* based index, Excel seems to see the link and it honors it when saving the spreadsheet.
So, I ended up with something like:
<c ... cm="1"/> (I'm dealing with cell metadata, but the concept is equivalente to value metadata)
<metadataTypes count="1">
  <metadataType name="MyMetaType" .../>
</metadataTypes>
<futureMetadata count="1" name="MyMetaType">
  <bk>
    <extLst><ext
uri="http://example" xmlns:x="http://example"><x:val>87</x:val></ext></extLst>
  </bk>
</futureMetadata>
<cellMetadata count="1">
  <bk><rc
t="1" v="0"/></bk> 
</cellMetadata>

Please help me how to use SAX parser in J2ME.
Is there any function to find the value of a particular element from a XML file?
I am able to get Element name, Values, Attributes. But control is not in my hand, DefaultHanldler automatically invokes Character method, then only I am able to get values. But I don't know when this method gets invoked.
Is there any way or method so that I can get value of any element or attribute just by passing element name as parameter in SAX parser?
Is there any other parser through which I can perform this task in J2ME?
Thanks in advance.
