XMLDOM package/ Plsql XML parser

HI, I'm trying to build XML document using plsql parser 1.0.2 using xmldom package.
The XML output given is not consistent and the AppendChild Call removed the Root node (from the XML document). This result in incomplete XML document.
-------Expected ouput format (though header is not properly displayed---------------
<Request>
<Requestor RequestorID="0100" RequestorType="SP"/>
<ValidateAddrReq IndividualRequestId="23456789">
<Address2
City="Manhattan" State="NY" Zip="10007">
<Addrnum Value="140"
AddrNumSuffix=""/>
<StreetName StreetN
ame="WEST" DirStreetPrefix="E" DirStreetSuffix="W" StreetTypeCode="ST"/>
</Address2>
</ValidateAddrReq>
</Request>
The same code is working in the Windows NT environment and when I moved to the actual AIX environment it is not working though, I'm not sure if there is any releation. Here the rood node and its child is chopped off.
And also the formatting is different.
-----------In AIX op. system, I'm getting ------------
<ValidateAddrReq IndividualRequestId="123123">
<Address2 City="BRONX"
State="NY">
<Addrnum Value="3040">
<StreetName
StreetName="BOSTON" StreetTypeCode="RD">
<Structure
StructType="BLDG" StructInfo="1A"/>
</StreetNam
e>
</Addrnum>
</Address2>
</ValidateAddrReq>
application Code:
null

I will look at using that, however in this example I dont belive that to be the problem as the string is < 4k.
Ive now got the error message, it was being handled as an exception before and not reporting the error message.
The error is
ORA-20100 Error Occured While Parsing unexpected EOF.
Any more suggestions
Regards

    PLSQL XML parser modified examples
    Hello Fine Folks at Oracle xml team
    Here i am again from Copenhagen Denmark.
    To day i would like to question/discuss the following things
    ItFs all about the PL/SQL XML parser which i have installed on
    my OracleServer 8i Enterprice
    Question 1
    If i want to modify DOMSAMPLE.sql or write my own program, i now
    have very few choices
    Where to look for intelligent answers to my questions.
    1. My only source here is the package body for XMLPARSER which i
    have installed under
    the user SCOTT/TIGER. I made a dump of all that code to the
    printer
    So thats my xml
    manual together with the domsample.sql
    QUESTION . Where do i find programmers reference etc. etc. etc.
    Question 2
    2. Many of the *.xml examples here on my platform have a design
    where elements have no attributes;
    But still they are "placeholders" for elemt values.
    Here is the DomSample source part iFam referring to
    -- get all elements
    nl := xmlparser.getElementsByTagName(doc, '*');
    len1 := xmlparser.getLength(nl);
    -- loop through elements
    for j in 0..len1-1 loop
    n := xmlparser.item(nl, j);
    e := xmlparser.makeElement(n);
    dbms_output.put_line(xmlparser.getTagName(e)

  • PLSQL XML Parser core dump

    We are getting core dumps when using the plsql parser on our
    data. The data files are about 500K.
    We are on Oracle 8.1.5 on a Digital UNIX V4.0E.
    Would you like to see the dumps or the trace files?
    null

    We are having the same problem in OAS PLSQL cartridge
    application using PLSQL XML parser. Core dumps are spontaneous
    while the size of XML file is quite small (~20-50K). The trace
    file has error messages like "Session exceeded soft sessionspace
    limit of 0x100000 bytes" or "Address not mapped to object.
    ORA-07445: exception encountered: core dump...". We are using OAS
    4.0.8 and Oracle 8.1.5 for Solaris. OAS and DB Instance are on
    the same box. But everything works fine when using OAS on
    separate NT server.

    As our application uses AXIS to do WebServices, we have removed the default oracle xml shared library by using remove-inherited in orion-application.xml. In addition, we package our own xerces in our application ear file. It looks like PDK is looking for oracle xml parser resulting in the NoClassDefFoundError exception.
    The above exception is thrown if I access the JDPK provider URL after accessing our application.
    However, if I restart the OC4J and ccess the JPDK provider URL without accessing our application, I get the following error

    On further test, If I let the default oracle xml parser be loaded, then I do not get the the exception.
    I have removed the following lines from orion-application.xml
         <imported-shared-libraries>
              <remove-inherited name="oracle.xml"/>
         </imported-shared-libraries>
    Now, If I access the JPDK provider URL
    http://ple-fjunod.peoplesoft.com:9820/pspc/providers/psprovider/ps/EMPLOYEE
    I get the excepted page
    Congratulations! You have successfully reached your Provider's Test Page.

    pdkjava.jar version: 10.1.3.2.0
    Can someone please tell me that if I remove the inherited default oracle XML parser using remove-inherited tag in orion-application.xml, how do I make the JPDK use my own packaged xerces XML parser.

  • Creating XML File Using xmldom Package

    How can I create an XML file from scratch using the PL/SQL xmldom package?
    I want to create an XML file using the xmldom package instead of building the individual tags as strings of VARCHAR2 character data. There is quite a bit of documentation regarding manipulating input XML files using DOM -- but not for creating XML files from scratch given known "tagnames" (<lastName>) and retrieved database "values" ("Smith").
    <person>
    <lastName>Smith</lastName>
    </person>
    Is there any documentation that you can recommend?
    Thank you.

    Here is an example.

  • Create document with PL/SQL xml parser

    Hello,
    I'm trying to create a document with PL/SQL package xmldom on 8.1.7 and write to a file.
    The problem is that my file is empty when it's created.
    Can anyone send me an example of this simple problem or fullfill my example so it's works.
    As you understand I'm new in using XML. :)
    My example is:
    declare
    doc xmldom.DOMDocument;
    n xmldom.DOMNode;
    e xmldom.domelement;
    t xmldom.domtext;
    begin
    doc := xmldom.newdomdocument;
    t := xmldom.createtextnode(doc, 'ROOT');
    n := xmldom.makenode(t);
    doc := xmldom.makedocument(n);
    xmldom.writetofile(doc, 'd:\orant\xdk\plsql\demo\test.xml');
    end;
    Regards

    Your problem may be memory for the JavaVM. Remember, the PL/SQL
    parser uses the Java XML Parser APIs which run in a VM instance.
    Are you running Oracle 8i? If you are you can access our Java
    XML parser loaded in 8i's VM directly from your PL/SQL code.
    That is in fact how our PL/SQL Parser does it.
    Finally, we have no experience loading other XML Parsers into
    Oracle.

  • Plsql dom parser slow in 8i

    Hi,
    I am using oracle 8.1.7.4
    I am using plsql parser (DOM parser by default) to parse a xml document. It takes 2 seconds to parse a doc of size 20K having about 500 tags. task is to parse such 60K documents in a day where concurrent parsing requests might be 1000.
    Does anyone know, how to improve the parsing time? I have used xmlparser and xmldom packages(built-in).
    Thanks in advance.

    Thanks Shushant. It helped me.

  • XML parsing - Thanks Andrew Clarke,info you wanted to answer

    Andrew ,
    First of all thanks for responding.It was indeed very helpful of you.I have put your questions here just and have answered it
    " This is a tricky thing to do. Parsing and processing a document in the database is relatively straightforward. Allowing the user to make changes to it is slightly stickier.
    Before we can be of any help you need to give us some more info:
    Which version of the database are you using? (9i has lots more functionality)
    How are you intending to display the information to the user?
    Is your user going to be editing the XML tags or just the content?
    Are you using XML SCHEMA or DTD?
    Do you know there's an XML forum? (Check the jump to any forum drop down)
    1)I am using database :- info
    Connected to:
    Oracle8i Enterprise Edition Release 8.1.7.0.0 - Production
    With the Partitioning option
    JServer Release 8.1.7.0.0 - Production
    I hope this information is enough.Another thing i wanted to know is how to check for oracle jvm intallation.Because it is needed for oracle xdk installation.
    2) I intend to parse the xml file stored as a blob object in the backend and display the information in the front end ( Oracle forms6i) interface.
    3) The user sees only the content and can edit only the content ,issuing save command writes back this data into the xml file and saves it back to the database as the blob object.
    Yes i know XML discussion forum,but please can you guide me a little in my direction ,i thought it would be more useful to write in this forum (deals with pl/sql).Atleast a lead is enough.
    Can you please suggest some help for the questions that i have:-
    1)I don't know whether i have oracle JVM installed.The oracle xdk kit install notes say so.So how to check it and get it.Help notes say that a xdk kit for 9i version will also work with 8i version( backward compatibility ).Can you offer some advice on this whether this is possible( The xdkload utility says so.)
    2)Is it possible to,after having build a tree thro' parsing process and to go through it accessing the nodes and the values .Also is it possible to write to this tree at the particular point and have the tree saved back to xml document.This will save me a lot of job.Please feel free to help me or atleast suggest some lead points if you know if this can be done.A hyper link ,if you know,which details these steps are also enough.
    Regarding the XML schema or DTD ,please give me some more time.
    One last question(if i am not bugging you) when the xdkload utility loads the xdk pl/sql package with -dbver to 8i ,will it support all the command in it to be executed on the 8i backend.
    (http://technet.oracle.com/support/tech/xml/xdk_plsql/ softwares section)
    Andrew ,i will feel really grateful if you can help me with these issues.Anyway Thanks for taking so much efforts in giving me some tips.
    Regards
    gopal

    I hope this information is enough.Another thing i wanted to know is how to check for oracle jvm intallation.Because it is needed for oracle xdk installation.The banner that comes up when you log on shows you that you are running:
    JServer Release 8.1.7.0.0 - Production so that means Java is enabled. A good start.
    Help notes say that a xdk kit for 9i version will also work with 8i version( backward compatibility ).We are running with XDK 9i in 8173 databases without any major issues. n fact I recommend it, as there are a couple of nasty bugs in the 8i XDK that render it virtually unusable. However there is a whole bunch of functionality in the 9i XDK that relies on the XML datatype that was introduced in the 9i database.
    2) I intend to parse the xml file stored as a blob object in the backend and display the information in the front end ( Oracle forms6i) interface.
    3) The user sees only the content and can edit only the content ,issuing save command writes back this data into the xml file and saves it back to the database as the blob object.Why not store the data in tables? It is much, much easier to build Forms applications using tables than to build them using XML documents. Disassembling XML documents into tables is relatively straightforward and so is re-constituting them if you ever need to show someone the XML. In Oracle 9i r2 this is what Oracle does by default with the XML datatype.
    2)Is it possible to,after having build a tree thro' parsing process and to go through it accessing the nodes and the values .You build the tree using xmlparser.parseClob() followed by xmlparser.getDocument().
    You walk the DOM using the methods in the XMLDom package to navigate to any given node. Then you use xmldom.getNodeValue(} to retrieve the data in that node. This only works for nodes of type xmldom.text_node, so you'll need to test for that. It also fails if the node has a null value. Finally bear it mind that according to DOM principles the content of a node is a child[i] of that node.
    Given this fragment:
    <employee>
        <empno>1234</empno>
    </employee>I want to get the employee number. So:[list]
    [*]I generate a list of empno nodes using node_list := xmldom.getElementsByTagName(x_doc, 'empno');[*]I navigate to the node I want using el := xmldom.item(node_list, 1)};[*]I then navigate to the text using text_node := xmldom.getFirstChild(el);[*]I navigate to the node I want using emp_no := xmldom.getNodeValue(text_node};[list]
    There may be whizzier ways of doing it but this way is clear and it works.
    Although the documentation that comes with the XDK isn't that bad you will find some additional info in the onlineshttp://technet.oracle.com/docs/products/oracle9i/doc_library/release2/appdev.920/a96621/adx20ppl.htm#1656. have a look at the domsample.sql script. It's actually quite helpful.
    Also is it possible to write to this tree at the particular point and have the tree saved back to xml document.I haven't done this myself, but I would have thought you would write stuff using the method outlined above but using xmldom.setNodeValue. There are various WriteTo... in the xmldom package.
    Now for the bad news. None of this works with BLOBs. You have to use CLOBs, VARCHAR2s or external OS files. Sorry.
    Good luck, APC

  • ?xml version = '1.0' encoding = 'ASCII'? pl/sql xml parser

    When ever I parse a document which has the
    <?xml version = '1.0' encoding = 'ASCII'?> tag as the first line hangs the pl/sql xml parser . If I remove the "encoding = 'ASCII'" from the file everything works fine ! What is the problem ?
    version 8.1.6 / plsql parser v2 / hpux 11x
    Here is the input file
    <?xml version = '1.0' encoding = 'ASCII'?>

    Here is my program
    declare
    p xmlparser.parser;
    doc xmldom.DOMDocument;
    dir varchar2(100) := '/apps/oracle/drugstore';
    errfile varchar2(30) := 'err.txt' ;
    inpfile varchar2(30) := 'person.xml';
    nl xmldom.DOMNodeList;
    len number;
    n xmldom.DOMNode;
    new_node xmldom.DOMNode;
    node_name varchar2(100);
    node_value varchar2(100);
    begin
    -- new parser
    p := xmlparser.newParser;
    -- Set some characteristics
    xmlparser.setValidationMode(p, FALSE);
    xmlparser.setErrorLog(p, dir&#0124; &#0124;'/'&#0124; &#0124; errfile );
    xmlparser.setBaseDir(p, dir);
    -- parse input file
    xmlparser.parse(p, dir&#0124; &#0124;'/'&#0124; &#0124;inpfile);
    -- get document
    doc := xmlparser.getDocument(p);
    -- get all elements
    nl := xmldom.getElementsByTagName(doc, '*');
    len := xmldom.getLength(nl);
    dbms_output.put_line('Length='&#0124; &#0124;len);
    -- loop through elements
    for i in 0..len-1 loop
    n := xmldom.item(nl, i);
    node_name := xmldom.getNodeName(n);
    -- get the text node associated with the element node
    n := xmldom.getFirstChild(n);
    if xmldom.getNodeType(n) = xmldom.TEXT_NODE then
    node_value := xmldom.getNodeValue(n);
    if node_name='lastname' then
    dbms_output.put_line('The value you are looking for is -->:'&#0124; &#0124;node_value);
    if node_value = 'GHANTASALA' then
    xmldom.setNodeValue(n,'TEST2');
    end if;
    end if;
    end if;
    end loop;
    new_node := xmldom.makeNode(doc);
    xmldom.writeToFile(new_node, dir &#0124; &#0124;'/'&#0124; &#0124;'mod.xml');
    end ;
    null

    The encoding header is actually generated by
    by the following piece of code in my pl/sql program .
    new_node := xmldom.makeNode(doc);
    xmldom.writeToFile(new_node, dir &#0124; &#0124;'/'&#0124; &#0124;'mod.xml');
    Since this is a document created by the pl/sql parser, I assume there is some meaning to it !
    Also why is it hanging ? PL/sql parser should tell me that it is not a valid string !

  • XML Parser for PL/SQL

    Hi,
    I have to produce and manipulate XML documents in PL/SQL. I have downloaded the XML Parser for PL/SQL from Oracle's web site.
    Can anyone please:
    1. Point me to some examples illustrating XML DOM manipulation with PL/SQL.
    2. Any information about PL/SQL packages used for XML manipulation.
    I am using Oracle 8i version 8.1.6
    Thanks,
    Rossen
