Parser for XML

Hi you all,
I would just like to hear from you, what parser do you usually use to work with XML.
JAXP or JDOM.
THere so many choices...
Many Thanks,
MeTitus

`hi
DOM is mainly used if we have to build or alter the xml docs and sax if we have to only read the xml docs
DOM is mainly prefered in the real world
hope this helps

Custom parser for XML

Hello forum,
I want to put in iFS XML documents with binary content encoded in base64.
I have created "PrintedDoc" base on "Document" with new attributes: Name, Pages, PeportName.
I created test XML file and iFS parses it just fine.
This is an example of XML file:
<?xml version = '1.0' standalone = 'yes'?>
<PrintedDoc>
<Name> Angebot-Nr. 123 vom 12.06.2002.pdf </Name>
<FolderPath> /printed/Angebote </FolderPath>
<Pages> 3 </Pages>
<Format RefType="name"> PDF </Format>
<ReportName> Angebot </ReportName>
<Content>AABC-+.....AABCD</Content>
</PrintedDoc>
Now I want to decode content back into binary format and store binary data. I have written java class for decoding. I will write a parser that decodes base64 content into binary data.
My question: How I can register my parser for that xml document? I read about including namespace into document and registering custom XML parser, but this will give me the whole xml document as incoming data.
I would appreciate if you share your experience or give some hints.
TIA
Alexandre

Hi again,
I'm trying to write XML pareser implementing XmlParserInterface. I have implemented parse methods and used IfsXmlParser.CreateDOM to get parsed XMLDocument.
As far as I know, my xml parser should be instaneiated by IfsXmlParser, which in turn calls one of parse methods. The problem is that XmlParserInterface doesn't contain constructors to implement. For example, interface Parser has constructor with argument of type LibrarySession.
How I can get current LibrarySession from my XML parser? Should I implement both interfaces Parser and XmlParserInterface?
Thanks for any help,
Alexandre.
PS: are Java sources of iFS available somewhere? It would be helpful to get knowledge of how the things working. There is no documentation for creating XML parsers. I have only found about writing usual custom parsers in Developer Guide and a little in iFS API. But that is very scant. :(((

Parser for XML as output from DB..

Hi Guys,
Can some one tell me a parser which can take a query and gives the output as an XML format. And takes an XML file and puts the data into DB. pl. let me know from where i can download the parser. and if u have any sample code pl give me.
Any help would be appreciated greatly.
Thanks in advance.
Anil([email protected]).

Thanks alot Bernhard.
I got it. But now i would like to know, can i specify the XML format to be generated(DTD kind of thing)when we make a query, like the query will be getting the data of two tables say master and child. so for each record of master there can be multiple childs. at that time i dont want the master data come along with all the childs(master data duplication should not be there). let me put like this. In the master tag there can/should be multiple child tags(sub tags). can this be done using the XSU or XDK ? In the same way can we insert data into two tables at a time. its like we will be taking the data from two tables do some operations reduce some data and then insert into two tables again. can this be achieved with xml file. And i would like to know how to generate one xml for one master record(including its child records, going to be join or sub query etc..) Am i clear on to my question ? If u have any sample data on this could u give me. once again thanks alot for the url.
Any help would be appreciated greatly.
Thanks in advance.

Use the createTextNode method to create a new text node. Then
convert the DOMElement to a DOMNode using makeNode. Now, you can
use appendChild to append the text node to the DOMElement.

SAX, incor. data for XML element, XML 1.1 doc (1.0 ok) in JRE 6 (JRE 5 ok)

Hello,
for some reason, the test case below fails when driven with Java 6. Looks like, when long string data is stored in a XML element, DocumentHandler's characters() method will be provided with incorrect data.
With XML 1.0, parsing works fine in all my tests, Apache Xerces, JRE 5, JRE 6.
With XML 1.1., parsing works fine with Apache Xerces, JRE5 but not with JRE6.
I've checked it with latest JRE 6 update 4.
Anyone else xperiencing such problems with XML1.1 parsing when using JAXP bundled with Java 6?
I've tried to file a bug at bugdatabase, but for some reason I got no response for my issue - so I'm trying the forum now ;-)
Thanx for comments

thanx, DrClap, haven't seen the "code" button for some reason, code is attached again
The output of my test is like this for JRE6 (truncated)
xml_sun 456789 This is is some text 0. 0123456789 This is some text 1.
xml_apache 0123456789 This is some text 0. 0123456789 This is some text 1.
Notice, xml_sun not only starts wrong ("0123" missing) - for some reason, the text there is not "This is some text" but "This is is some text" - very interesting in a way. I guess there's an issue with repeated text chunks ...
So, the data in my XML element is kind of changed, the length of the string is okay but the characters are "misplaced" or so :-) I thought about a problem with StringBuffer first, but the StringBuffer works fine for Apache ... so I really think there's an issue with JRE 6's parser for XML 1.1

XML Parser for C++ v2 on HP-UX 11.00

Hi,
We are using XML parser for C++ v2(2.0.1) on HP-UX 11.00.Oracle version is 8.0.5. Our application is dumping core .analyzing the core gives pointers to Oracle function calls. We found that some datatypes in parser's oratypes.h (e.g ub4,sb4)were not in consistence with datatypes in native Oracle's oratypes.h.how to solve this problem? is there any linkage or Includepath order recommended to solve this? let me know if u know any solution/workaround

Was it definitely xmlparsev2.jar that you had to load?
I recently started going through some of these examples as well and found that the standard xml parser was there but that I needed to load the xml parser for PL/SQL. I did this using loadjava from a subdirectory within the xdk directory and everything worked fine.

Java +XML (SAX) Parser for Oracle 8.1.5 EE

Hi there :)
I am looking java classes for SAX to parse XML. I cannot find a valid parser, cause after downloaded from Oracle XDK for java, when i try to load this calasses i get a messages that i alot of classes connot be resolved.
If somebody have valid classes on Ora 8.1.5 please send me mail.

Have i possibilities to using some javatypes in oracle java stored procedure if this class is not loaded into db?
Cause i would like to create a java stored procedure to parse and insert some data from xml. I was thinking to pass xml file name as a parameter to my java procedure.
I must use Oracle 8.1.5 with jdk 1.1.7, and the best parser for me is SAX.
Please help.
Have i possobilities to use class inside oracle, which are placed outside oracle?
Something like classpath, where can i modify value (but classpath inside oracle)?

What is the best solution for xml parsing?

Hi. I've got a huge problem with the XML xtra. When I was
running my application the memory usage started to grow up
and up...I've only parse the XML once on the beggining, so I
thought that maybe it was a problem with the garbage
colector, etc...after a loooong time, I've realized that
every time that I access some node to get some information, the
movie uses more and more memory. I've read in the groups that
the XML xtra is known for memory leaks issues, so I've
did what they suggested and changed to the dom-lingo cast
(the one from shocknet)...The problem is that now when I'm
parsing the XML it takes like 50 seconds (with the XML xtra
it was like 2 secs) something that I think it would be too slow
for the end-user... I don't know if there's a faster (and
free) alternative...
I'm using Director MX and my XML file it's about 550 kb
Thanks.

It's reported tht the main memory leak has been fixed as of
10.1, a more
mino r node reference related leak can be worked around
http://www.killingmoon.com/director/bugs/xml_parser/
A workaround some used before the xtra beng made usable was
to call on
the Flash XML object available via in the flash xtra, here's
an article.
"Reading XML Into Director MX 2004 With a Simple Flash
Object"

Bug fixes for #920536, i.e. Cannot access element attributes via
XSLT; #898423. i.e. ElementDecl's in DTDs; #774774, i.e. DOM
extensions using XSL pattern matching; #863890 i.e. SAX
IOException not thrown.
New APIs in the following new interface:
1. oracle.xml.parser.v2.NSResolver
- resolveNamespacePrefix( find the namespace definition in scope
for a given namespace prefix )
New APIs in the following classes:
1. oracle.xml.parser.v2.XMLNode
- selectNodes( Selects nodes from the tree which match the given
pattern; client can provide an NSResolver implementation to
resolve namespace prefixes in the pattern ).
2. oracle.xml.parser.v2.ElementDecl
- getParseTree( Returns the root Node of Content Model parse
tree, which could then be traversed node by node using
getFirstChild() and getLastChild(). The Node types are: PLUS,
COMMA, ASTERISK, ELEMENT, QMARK ).
This is the first beta patch release for v2.

Options for XML parsing in WAS 6.20 ABAP and higher

Hello Experts,
   What options are available to me for working with XML documents in SAP R/3 4.7? I am working on SAP WAS 6.20 ABAP and was wondering which tools/techniques I can use for parsing XML files?
   I am developing an ABAP program and primarily need to be able to parse XML documents. I need to be able to traverse up and down their data structures (trees/nodes/elements/etc.).
   In SAP R/3 4.6 I used to use the iXML library but it seems that there are many advanced and powerful features included in SAP WAS 6.20 ABAP and up.
   Could someone please give me a summary of and their opinions on some these "newer" options?
Thanks,
- Vik.

Hi Vik,
   There are two ways you can parse/interpret XML documents in ABAP -
   1. iXML - Which you have already used in 46 release. It wasn't easy to use set of functions but still it was possible to parse documents using iXML library. In WAS 6.20 you can now use class CL_XML_DOCUMENT which is much more easier to use than iXML library. It is bilt on top of iXML using the same DOM model.
2. XSLT - Useing XSLT_TOOLS or XSLT transaction you can create XSLT programs to transform XML to ABAP data objects and then work with ABAP data objects. In this case you have the option of using some other tool like XMLSPY to write the XSLT and then copy that to SAP.
From your post it looks like you will probably have to traverse the tree in unpridictable way, probably DOM based parsing using CL_XML_DOCUMENT is more suitable for you.
Cheers,
Sanjeev
