Create XML - DOM or SAX
I want to create a XML file from a table and store into predefined location. The total number of records are not more than 100.
I read about both technologies but which one i shld go for ?
Is it that for creaion go for DOM,
for parsing SAX (if not too much traversal) else DOM?
regards
Manisha
this really depends on what you are trying to accomplsh. If you are needing to use the data, then use the DOM. This will LOAD ALL the data into memory; may not be a problem with the small number of records (depending what is in the records). But then you have the tree to interact with.
If you simply need to react to the data as it is read, then parse the xml as it is read as perform the necessary actions.

How to Create XML file with SAX parser instead of DOM parser
HI ALL,
I am in need of creating an XML file by SAX parser ONLY. As far as my knowledge goes, we can use DOM for such purpose(by using createElement, creatAttribute ...). Can anyone tell me, is there any way to create an XML file using SAX Parser only. I mean, I just want to know whether SAX provides any sort of api for Creatign an element, attribute etc. I know that SAX is for event based parsing. But my requirement is to create an XML file from using only SAX parser.
Any help would be appreciated
Thanx in advance
KaushikHi,
You must write a XMLWriter class yourself, and that Class extends DefaultHandle ....., the overwrite the startElement(url, localName, qName, attributeList), startDocument(), endElement().....and so on.
in startElement write your own logic about how to create a new element and how to create a Attribute list
in startDocument write your own logic about how to build a document and encodeType, dtd....
By using:
XMLWriter out = new XMLWriter()
out.startDocument();
Attribute attr1 = new Atribute();
attr1.add("name", "value");
out.startElement("","","Element1", attr1);
Attribute attr2 = new Atribute();
attr2.add("name", "value");
out.startElement("","","Element2", attr2);
out.endElement("","","Element2");
out.endElement("","","Element1");
out.endDocument(); -
Creating XML DOM with Escape characters
I am using DOM to generate xml fie. Setting some chinese character string which is hardcoded for one of node value.
When i am setting value to xml node i am passing it as "∆" but DOM automatically converts this string and store into xml file as "∆"
Because of this i can not show proper chinese characters in PDF. How i can avoid this ? Is it possible to store chinese character as "∆" itself inside xml?
regards
ManishaWhen setting the value from java you can use the real unicode character. Assuming with ࢞ you want to write the Unicode-Character at Codepoint 0x2206 you could just use "\u2206" in a java String to encode it. The XML library has to take care of how it's encoded in the final xml file.

How to Parse a string into an XML DOM ?
Hi,
I want to parse a String into an XML DOM. Not able to locate any parser which supports that. Any pointers to this?Download Xerces from xml.apache.org. Place the relevant JAR's on your classpath. Here is sample code to get a DOM document reference.

XML parser used in Oracle...DOM or SAX?
Hi,
My db version:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
PL/SQL Release 11.2.0.1.0 - Production
CORE 11.2.0.1.0 Production
TNS for Linux: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production
Question:
I get an XML feed and load it into a temporary table T1.
My requirement is to load it in the exact sequence as I get the rows in xml and also populate a column in the temporary table as a sequence like 1 2 3 corresponding to the rows in the xml
When I do load the xml, it gets loaded in same order the xml feed is sent. So no worries.
But while I was researching I came to know that Oracle could use either DOM or SAX parser. If it uses SAX, then the order is maintained as in XML. But if DOM is used, the order wont be maintained.
Please let me know, how I can ensure that the xml order is maintained as it is while loading into temp table.I apologize, here is more details
{code}
CREATE TABLE XMLTEMPTBL
PARAM NVARCHAR2(30 BYTE),
PARAMORDERSEQ NUMBER(3)
XML format:
<?xml version="1.0"?>
<ROWSET>
<ROW>
<PARAM1>abc</PARAM1>
</ROW>
<ROW>
<PARAM2>def</PARAM2>
</ROW>
<ROW>
<PARAM3>ghi</PARAM3>
</ROW>
<ROW>
<PARAM4>jkl</PARAM4>
</ROW>
</ROWSET>
PROCEDURE insertparams (p_xmldoc IN CLOB)
IS
insctx DBMS_XMLSTORE.ctxtype;
ROWS NUMBER;
BEGIN
/*inserting insdoc into a temp table*/
insctx := DBMS_XMLSTORE.newcontext ('xmlTempTbl');
ROWS := DBMS_XMLSTORE.insertxml (insctx, p_xmldoc);
DBMS_XMLSTORE.closecontext (insctx);
END;
I want to insert into table this way:
select * from xmltemptb;
PARAM PARAMORDERSEQ
abc 1
def 2
ghi 3
jkl 4
{code}
My procedure is not 100% correct (but it gives an idea what code I am using to load into table), but I want to ensure the xml rows are loaded into the table in the same sequence. -
How to remove element namespaces in XML file using DOM or SAX?
Hi Guys,
I developed a JAVA mapping in XI to add name spaces for XML file, after mapping,name spaces xmlns="http://www.mro.com/mx/integration" and xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" were added correctly, but for some nodes, such as <Header> and <Content>, a name space xmlns="" was added automatically.Please check below files to compare.
It looks like be added automatically by XI. I didn't process anything for these nodes in JAVA program.
Now the issue is, how can I remove these redundant namespaces? Such as xmlns="".
Can I remove them using DOM or SAX in JAVA Mapping?
Thanks in advance.

Edited by: Eddie Zhang on Feb 14, 2008 9:24 AMHi Milan,
Thanks for your replay.
Actually when I used module XMLAnonymizerBean to convert namespaces, the header of XML, such as <?xml version="1.0" encoding="UTF-8"?> was converted to format <?xml version='1.0' encoding='UTF-8'?>, quote was converted to single quote. Although I set parameter anonymizer.quote = ", it still didn't work, single quote appeared instead of quote.
I'm not sure why this happened. Can anyone help to clarify this?
Thanks

Filling tab of an XML document created by DOM
have a problem with filling tab of an XML file created by DOM
I used this code to create the document:
public class DOMCreation {
public void createDOM( String a, String b ) {
Document doc = new DocumentImpl( null );
// Il codice che segue � indipendente dal particolare parser utilizzato
// Creazione dell'elemento root del documento, identificato dal tag <DOCUMENT>
Element root = doc.createElement("DOCUMENT");
doc.appendChild(root);
// Creazione ed inserimento di un nodo
Element element1 = doc.createElement("USERNAME");
root.appendChild( element1 );
// Creazione ed inserimento di un secondo nodo discendente di <DOCUMENT>
root.appendChild( doc.createElement("PIN") );
System.out.println( a );
System.out.println( b );
try {
serializeDocument( doc, new FileOutputStream("d:/doc.xml"));
} catch (FileNotFoundException e) {}
private static void serializeDocument(Document doc, OutputStream output) {
try {
DOMSerializer ser = new XMLSerializer( output, null);
ser.serialize(doc);
} catch (IOException e) {
System.err.println("I/O exception while serializing document: " + e.getMessage());
}The code lines:
System.out.println( a );
System.out.println( b );
had the purpose to check if these two parameters were passed by another procedure. These two parameters, however, represent the content to be filled in the tag of XML document created by DOM.
About the other question on "what parser do you use", I'm using Apache's Xerces. However that's the "import" that I include in this procedure:
import org.apache.xerces.dom.DocumentImpl;
import org.apache.xerces.dom.NodeIteratorImpl;
import org.apache.xml.serialize.*;
import org.w3c.dom.*;
import org.w3c.dom.traversal.*;
import java.io.*; -
When I create an xml document and print it to a string I find that I can only get 900 characters at a time from the output string (using substring) even though its length is reported as > 900

How to SAVE a updated XML DOM Data to the file?
Hi
I am able to load an XML file into a XML DOM object using JAVA (xerces). I have update the required data in the DOM.
But I am NOT able to save back the data to the physical file.
Will appreciate if you can help me ASAP.Hi Krishar,
Check out the jaxp new release on java.sun.com. This api has classes and methods to help you do the same.
sample code:
try
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
java.net.URL url = this.getClass().getResource(XML_FILE);
java.io.File thsFile = new java.io.File(url.getFile());
DocumentBuilder builder = factory.newDocumentBuilder();
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer();
document = builder.parse(thsFile);
//You can do any modification to the document here
DOMSource source = new DOMSource(document);
StreamResult result = new StreamResult(thsFile);
transformer.transform(source, result);
catch (TransformerConfigurationException tce)
System.out.println("\n** Transformer Factory error");
System.out.println(" " + tce.getMessage());
Throwable x = tce;
if (tce.getException() != null)
x = tce.getException();
x.printStackTrace();
catch (TransformerException te)
System.out.println("\n** Transformation error in add:");
System.out.println(" " + te.getMessage());
Throwable x = te;
if (te.getException() != null)
x = te.getException();
x.printStackTrace();
catch (SAXException sxe)
System.out.println("sax exp" + sxe.getMessage());
catch (Exception ex)
System.out.println("exc exp" + ex);
ex.printStackTrace();
Hope this will help you XML_FILE is constant representing the path of the file. It should be in classpath. The program essentially parsing a xml file and creating dom document and then writing it back to the same file. you can do any modifications/write to other file etc...
Think this will suffice your requirement

Hi,
I have a very simple XML document as below:

All I want to do is retrieve the <content> and <date> elements. Should I be looking at using DOM or SAX?
Thanks.public class MyParser extends DefaultHandler{

private String date; // to hold the date value
private String nodeName; // to hold the nodeName
// xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
public MyParser(){ }

public void parse(String xmldoc){
try{
XMLReader reader = XMLReaderFactory.createXMLReader(vendor);
reader.setContentHandler(this);
// for xml document pass in as a String
InputSource inputSource = new InputSource(
new StringReader(xmldoc));
reader.parse(inputSource);
// comment out InputSource if you use a file instead and
// change reader.parse(inputsource) to reader.parse(xmldoc)
catch (Exception e) { System.out.println(e); }
// you would probably be catching SAXException and IOException
// but i use this to make it simplier
// xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
public void startElement(String ns, String name, String qName,
Attributes atts) throws SAXException {
nodeName = name;
// xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
public void characters(char[] ch, int start, int length)
throws SAXException {
if (nodeName.equals("content")
content += new String(ch, start, length);
else if (nodeName.equals("date")
date += new String(ch, start, length);
// xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
public void endElement(String ns, String name, String qName)
throws SAXException {
if (name.equals("content"){
System.out.println("Content value is = " + content);
content = "";
else if (name.equals("date")){
System.out.println("Date value is = " + date);
date = "";
else if (name.equals("message")){
System.out.println("End of XML doc and end of parsing");
}Many people use a boolean to save the where they are at (in the xml doc)
But since your xml doc is simple, it's not necessary
Also...If the content value is a long string..I would use a StringBuffer
instead of String (because the SAX Parser can call on the character() method multiple time...Normally, it only call on it once. Using StringBuffer reduce Object creating and reduce garbage collection. -
Difference between DOM and SAX
Difference between DOM and SAX
a sax parser is event driven meaning it processes the xml as it sees it and then forgets about it.
you have to implement what you want the parser to do wants it reaches a certain event
dom on the other hand keeps the whole structure of the message in memory as a tree.
so there are strengths and weaknesses in both.
you have to evaluate what you need -
Heap space error while creating XML document from Resultset

It was working fine from small result set object but when the size of resultset was more than 25,000, heap space error

Performance problem when creating XML-file
Hi,
I want to create a XML-file with customer data from an internal table. This internal table has appr. 62000 entries. It takes hours to create the elements of the file.
This is the coding I have used:
loop at it_debtor.
at first.
Creating a ixml factory
l_ixml = cl_ixml=>create( ).
Creating the dom object model
l_document = l_ixml->create_document( ).
Fill root node
l_element_argdeb = l_document->create_simple_element(name = 'argDebtors'
parent = l_document ).
endat.
Create element 'debtor' as child of 'argdeb'
l_element_debtor = l_document->create_simple_element(
name = 'debtor'
parent = l_element_argdeb ).
Create elements as child of 'debtor'
l_value = it_debtor-admid.
perform create_element using 'financialAdministrationId'.
l_value = it_debtor-kunnr.
perform create_element using 'financialDebtorId'.
l_value = it_debtor-name1.
21 child elements in total are created
endloop.
Creating a stream factory
l_streamfactory = l_ixml->create_stream_factory( ).
Connect internal XML table to stream factory
l_ostream = l_streamfactory->create_ostream_itable( table =
l_xml_table ).
Rendering the document
l_renderer = l_ixml->create_renderer( ostream = l_ostream
document = l_document ).
l_rc = l_renderer->render( ).
open dataset p_path for output in binary mode.
if sy-subrc eq 0.
loop at l_xml_table into rec.
transfer rec to p_path.
endloop.
close dataset p_path.
if sy-subrc eq 0.
write:/ wa_lines, 'records have been processed'.
endif.
else.
write:/ p_path, 'can not be opened.'.
endif.
form create_element using p_text.
check not l_value is initial.
l_element_dummy = l_document->create_simple_element(
name = p_text
value = l_value
parent = l_element_debtor ).
endform. " create_element
Please can anyone tell me how to improve the performance.
The method create_simple_element takes a long time.

Regard,
ChristineHi Christine!
There might be several reasons - but you have to look at the living patient, not only the dead coding.
You did not show any selects, loop at ... where or read table statements -> the usual slow parts are not included (or visible...).
Of course the method-calls can contain slow statements, but you can also have problems because of size (when internal memory gets swaped to disc).
Make a runtime analysis (SE30), have a look in SM50 (details!) for the size, maybe add an info-message for every 1000-customer (-> will be logged in job-log), so you will see if all 1000-packs are executed in same runtime.
With this tools you have to search for the slow parts:
- general out of memory problems, maybe because of to much buffering (visible by slower execution at the end)
- slow methods / selects / other components by SM30 -> have a closer look
Maybe a simple solution: make three portions with 20000 entries each and just copy the files into one, if necessary.

Christian -
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.
