HO w to use SAX parser to create an XML file on the fly

Hi All,
Currently I am using the DOM parser to create an XML file from a text file. But as the DOM takes much memory and inefficient, I need to convert the DOM translator to SAX translator. Can I do that ?? If YES then how to go about that and if NO then what may be the workaround for that.
Please help me out
Thanx in advance
kaushik

Incidentally, look at this thread:
http://forum.java.sun.com/thread.jsp?forum=34&thread=252415
It has an example of how to transform an XML file via XSLT. If you change this to use the zero-argument form of newTransformer, it will apply the "identity transformation" to your input, thus outputting your XML in valid form. Now you just need to figure out how to provide SAX input to this, and the JAXP download includes an example of that.

Can we create a XDP file on the fly

Hi All,
I am new to Live Cycle.
I want to know if we can create an XDP file on the fly and immediately using this XDP file can form server create a PDF?
Need this info urgently..
Thanks in advance.

There are several ways to do this. The third chapter in the
cookbook is a good place to start.
All things in ActionScript are based on objects. Constructing
them with the data needed for the ui information you will need and
then binding that data to your dashboard objects is basically what
you are going to be doing.
For me it makes the most sence to have an idea of what
different types of objects you will be creating and create some
extended components for those objects. Then when you recieve your
data, binary or xml, you can digest the configuration settings from
the layout and populate the constructor for each of your
components.
It sounds like you need to organize your layout structure in
a heirarchy and from that you can walk each branch and create each
set of things as you parse your data.
Without a bit more information as to what you are
specifically doing that is about as far as I can go minus adding in
some code along some line that I think might work.
Hope that helps some.

SAX: How to create new XML file using SAX parser

Hi,
Please anybody help me to create a XML file using the Packages in the 5.0 pack of java. I have successfully created it reading the tag names and values from database using DOM but can i do this using SAX.
I am successful to read XML using SAX, now i want to create new XML file for some tags and its values using SAX.
How can i do this ?
Sachin Kulkarni

SAX is a parser, not a generator.Well,
you can use it to create an XML file too. And it will take care of proper encoding, thus being much superior to a normal textwriter:
See the following code snippet (out is a OutputStream):
PrintWriter pw = new PrintWriter(out);
      StreamResult streamResult = new StreamResult(pw);
      SAXTransformerFactory tf = (SAXTransformerFactory) TransformerFactory.newInstance();
      //      SAX2.0 ContentHandler.
      TransformerHandler hd = tf.newTransformerHandler();
      Transformer serializer = hd.getTransformer();
      serializer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");//
      serializer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,"pdfBookmarks.xsd");
      serializer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,"http://schema.inplus.de/pdf/1.0");
      serializer.setOutputProperty(OutputKeys.METHOD,"xml");
      serializer.setOutputProperty(OutputKeys.INDENT, "yes");
      hd.setResult(streamResult);
      hd.startDocument();
      //Get a processing instruction
      hd.processingInstruction("xml-stylesheet","type=\"text/xsl\" href=\"mystyle.xsl\"");
      AttributesImpl atts = new AttributesImpl();
      atts.addAttribute("", "", "someattribute", "CDATA", "test");
      atts.addAttribute("", "", "moreattributes", "CDATA", "test2");
       hd.startElement("", "", "MyTag", atts);
String curTitle = "Something inside a tag";
          hd.characters(curTitle.toCharArray(), 0, curTitle.length());
    hd.endElement("", "", "MyTag");
      hd.endDocument();
You are responsible for proper nesting. SAX takes care of encoding.

How do I create individual xml files from the parsed data output of a xml file?

I have written a program (DOM Parser) that parses data from a XMl File. I would like to create an individual file with the corresponding name for each set of data parsed from the xml document. If the parsed output is Single, Double, Triple, I would like to create an individual xml file (Single.xml, Double.xml, Triple.xml)with those corresponding names. How do I create the xml files and give each file the name of my parsed data output? Thanks in advance for your help.

Approach to parse large number of XML files into the relational table.

We are exploring the option of XML DB for processing a large number of files coming same day.
The objective is to parse the XML file and store in multiple relational tables. Once in relational table we do not care about the XML file.
The file can not be stored on the file server and need to be stored in a table before parsing due to security issues. A third party system will send the file and will store it in the XML DB.
File size can be between 1MB to 50MB and high performance is very much expected other wise the solution will be tossed.
Although we do not have XSD, the XML file is well structured. We are on 11g Release 2.
Based on the reading this is what my approach.
1. CREATE TABLE XML_DATA
(xml_col XMLTYPE)
XMLTYPE xml_col STORE AS SECUREFILE BINARY XML;
2. Third party will store the data in XML_DATA table.
3. Create XMLINDEX on the unique XML element
4. Create views on XMLTYPE
CREATE OR REPLACE FORCE VIEW V_XML_DATA(
Stype,
Mtype,
MNAME,
OIDT
AS
SELECT x."Stype",
x."Mtype",
x."Mname",
x."OIDT"
FROM data_table t,
XMLTABLE (
'/SectionMain'
PASSING t.data
COLUMNS Stype VARCHAR2 (30) PATH 'Stype',
Mtype VARCHAR2 (3) PATH 'Mtype',
MNAME VARCHAR2 (30) PATH 'MNAME',
OIDT VARCHAR2 (30) PATH 'OID') x;
5. Bulk load the parse data in the staging table based on the index column.
Please comment on the above approach any suggestion that can improve the performance.
Thanks

I was not aware of Virtual column but looks like we can use it and avoid creating views by just inserting directly into
the staging table using virtual column.
Suppose OID id is the unique identifier of each XML FILE and I created virtual column
CREATE TABLE po_Virtual OF XMLTYPE
XMLTYPE STORE AS BINARY XML
VIRTUAL COLUMNS
(OID_1 AS (XMLCAST(XMLQUERY('/SectionMain/OID'
PASSING OBJECT_VALUE RETURNING CONTENT)
AS VARCHAR2(30))));
1. My question is how then I will write this query by NOT USING COLMUN XML_COL
SELECT x."SECTIONTYPE",
x."MACHINETYPE",
x."MACHINENAME",
x."OIDT"
FROM po_Virtual t,
XMLTABLE (
'/SectionMain'
PASSING t.xml_col                          <--WHAT WILL PASSING HERE SINCE NO XML_COL
COLUMNS SectionType VARCHAR2 (30) PATH 'SectionType',
MachineType VARCHAR2 (3) PATH 'MachineType',
MachineName VARCHAR2 (30) PATH 'MachineName',
OIDT VARCHAR2 (30) PATH 'OID') x;
2. Insetead of creating the view then Can I do
insert into STAGING_table_yyy ( col1 ,col2,col3,col4,
SELECT x."SECTIONTYPE",
x."MACHINETYPE",
x."MACHINENAME",
x."OIDT"
FROM xml_data t,
XMLTABLE (
'/SectionMain'
PASSING t.xml_col                         <--WHAT WILL PASSING HERE SINCE NO XML_COL
COLUMNS SectionType VARCHAR2 (30) PATH 'SectionType',
MachineType VARCHAR2 (3) PATH 'MachineType',
MachineName VARCHAR2 (30) PATH 'MachineName',
OIDT VARCHAR2 (30) PATH 'OID') x
where oid_1 = '99dd48cf-fd1b-46cf-9983';<--VIRTUAL COLUMN
insert into STAGING_table_yyy ( col1 ,col2,col3
SELECT x."SectionOID",
x."EventName",
x."OIDT"
FROM xml_data t,
XMLTABLE (
'/SectionMain'
PASSING t.xml_col                         <--WHAT WILL PASSING HERE SINCE NO XML_COL
COLUMNS SectionOID PATH 'SectionOID',
EventName VARCHAR2 (30) PATH 'EventName',
OID VARCHAR2 (30) PATH 'OID',
) x
where oid_1 = '99dd48cf-fd1b-46cf-9983';<--VIRTUAL COLUMN
Same insert for other tables usind the OID_1 virtual coulmn
3. Finaly Once done how can I delete the XML document from XML.
If I am using virtual column then I beleive it will be easy
DELETE table po_Virtual where oid_1 = '99dd48cf-fd1b-46cf-9983';
But in case we can not use the Virtual column how we can delete the data
Thanks in advance

How to create an XML file from scratch ?

Hi all,
I'm afraid that I will seem dummy, but I think I really misunderstand something or I'm trying to do something that is not possible...
I would like to create a XML file containing the following:<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="pl.xsl"?>
<!DOCTYPE playlist SYSTEM "pl.dtd">
<playlist id="2">
</playlist>I really need to have both the stylesheet and the DOCTYPE declarations... Does anyone know if this is possible ?
To create the XML Document, I am using the DocumentBuilder object from javax.xml package (jaxp-1.2-ea2). I think this, at least, is correct.
To print out the XML document I have tried to use :
- the Transformer from javax.xml package (jaxp-1.2-ea2) but I could obtain only the DOCTYPE declaration.
- the Serializer from Xerces parser (version 2.0.1) to print out the Document I am creating with the jaxp, but I was able only to obtain the stylesheet declaration...
So far I have just understand that there is a difference between Serializer and Transformer (one is serializing, and the other is transforming ;-)), but I couldn't figure out which one would be suitable to produce the XML file above...
I would really appreciate if one could help me with that ;-)
Thanks,
Karau

Could send me an example ?
For the moment I am using Transformer in that way:
     TransformerFactory tfactory = TransformerFactory.newInstance();
     try {
         Transformer transformer = tfactory.newTransformer();
         DOMSource source = new DOMSource(playlistDoc.getDocumentElement());
         StreamResult res = new StreamResult(new File(path));
         transformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM, PL_DTD);
         transformer.setOutputProperty(OutputKeys.INDENT, "yes");
         transformer.transform(source, res);
     catch (TransformerConfigurationException tce) {
         throw tce;
     catch (TransformerException te) {
         throw te;
     }

How to create an XML File for Gantt?

Hi Everybody.
I need a Gantt in Web Dynpro ABAP. I need it for the boss to do a Forecast for Vacation. I Hope this is understanding.
Did Anyone know how can i create a XML File for the Gantt at runtime?
Thanks
MSi

Hi Marcus,
the following link is to the JNet/JGantt developer doco
[JNet/JGantt Developer Documentation|http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/lw/uuid/f010ec31-9658-2910-3c83-c6e62904eceb]
included in this is the:
[Schema for XML|http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/com.sap.km.cm.docs/lw/webdynpro/jnet_jgantt%20developer%20documentation/schema/xml-spy/jnet-schema.html]
You can use this to build XML to represent a gantt like chart.
I did this to build XML to represent employee avaliablity - although we fronted the gantt through WD Java not ABAP - the java applet called is the same (I believe).
Don't underestimate the work required to tweek your data into a decent layout. It took me days.
There may be tools/api to help generate the XML - I don't know of them - I'd look forward to seeing any other replies to this thread from people who have used/built any. An example of a class that generates JNet XML - CL_SPI_UI_JNET - but this does not seem to be a Gantt display.
Cheers,
Chris

Problem in parsing an XML using SAX parser

Hai All,
I have got a problem in parsing an XML using SAX parser.
I have an XML (sample below) which need to be parsed
<line-items>
<item num="1">
     <part-number>PN1234</part-number>
     <quantity uom="ea">10</quantity>
     <lpn>LPN1060</lpn>
     <reference num="1">Line ref 1</reference>
     <reference num="2">Line ref 2</reference>
     <reference num="3">Line ref 3</reference>
</item>
<item num="2">
     <part-number>PN1527</part-number>
     <quantity uom="lbs">5</quantity>
     <lpn>LPN2152</lpn>
     <reference num="1">Line ref 1</reference>
     <reference num="2">Line ref 2</reference>
     <reference num="3">Line ref 3</reference>
</item>
<item num="n">
</item>
</line-items>
There can be any number of items( 1 to n). I need to parse these
item values using SAX parser and invoke a stored procedure for
each item with its
values(partnumber,qty,lpn,refnum1,refnum2,refnum3).
Suppose if there are 100 items, i need to invoke the stored
procedure sp1() 100 times for each item.
I need to invoke the stored procedure in endDocument() method of
SAX event handler and not in endelement() method.
What is the best way to store those values and invoke the stored
procedure in enddocument() method.
Any help would br greatly appreciated.
Thanks in advance
Pooja.

VO or ValueObject is a trendy new name for Beans.
So just create an item class with variables for each of the sub elements.
<item>
<part-number>PN1234</part-number>
<quantity uom="ea">10</quantity>
<lpn>LPN1060</lpn>
<reference num="1">Line ref 1</reference>
<reference num="2">Line ref 2</reference>
<reference num="3">Line ref 3</reference>
</item>
public class ItemVO
String partNumber;
int quantity;
String quantityType;
String lpn;
List references = new ArrayList();
* @return Returns the lpn.
public String getLpn()
return this.lpn;
* @param lpn The lpn to set.
public void setLpn(String lpn)
this.lpn = lpn;
* @return Returns the partNumber.
public String getPartNumber()
return this.partNumber;
* @param partNumber The partNumber to set.
public void setPartNumber(String partNumber)
this.partNumber = partNumber;
* @return Returns the quantity.
public int getQuantity()
return this.quantity;
* @param quantity The quantity to set.
public void setQuantity(int quantity)
this.quantity = quantity;
* @return Returns the quantityType.
public String getQuantityType()
return this.quantityType;
* @param quantityType The quantityType to set.
public void setQuantityType(String quantityType)
this.quantityType = quantityType;
* @return Returns the references.
public List getReferences()
return this.references;
* @param references The references to set.
public void setReferences(List references)
this.references = references;

throws SAXException
accumulator.setLength(0);
public void characters (char buf [], int offset, int len)
throws SAXException
accumulator.append(buf, offset, len);
public void endElement (String name)
throws SAXException
if (name.equals("first-name") )
firstname=accumulator.toString().trim();
if (name.equals("last-name"))
lastname=accumulator.toString().trim();
My problem is that i have to store the values of first-name and last-name.
but i have that in both
<authorizer> </authorizer> Tag and
<destination> </destination>
I need to retrive authorizer's firstname,lastname and
destination's firstname and lastname.
what i mean is i need to store authorizerFirstName,authorizerLastName
destinationFirstname and destinationLastname.
Pls let me know how to do that.
Thanks in advance.

hi pooja,
I think you are using DataHandler for parsing. Its deprecated. try using contentHandler . You can get the value of the element at the beginning. say for example
<firstname>sdfs</firstname>
the startElement will be firstname
the next method that it invokes will be characters method which has the text associated with the element. I am sending a sample code for your problem. try using it .
boolean m_boolinAuth = false;
boolean m_boolinDest = false;
boolean m_bAuthFName = false;
boolean m_bAuthLName = false;
public void startElement(String namespaceURI, String elementName, String qName, Attributes atts)
//does the logic for startElement
if(qName.equals("Authorization"))
m_boolinAuth = true;
m_boolinDest = false;
else if(qName.equals("Destination"))
m_boolinDest = true;
m_boolinAuth = false;
if(qName.equals("firstname"))
m_bFirstName = true;
if(qName.equals("lastname"))
m_bLastName = true;
public void characters(char[] ch, int start, int length)
//does the logic for characters.
String str = new String(ch,start,length);
if(m_bFirstName)
if(m_boolinAuth)
m_strAuthFirstName =str;
else if(m_boolinDest)
m_strDestFirstName = str;
m_bFirstName = false;
if(m_bLastName)
//same as first name case;
}

By the way, there is a new feature in Java 5.0 (Tiger) called "Annotations."
Since your code extneds DefaultHandler, you could specify a line with
@Override
before the definition of each of your methods. If you had used these, the compiler would have given an error since your methods did not override the methods of DefaultHandler.
(If your code implemented ContentHandler, by contrast, using @Override is invalid because you need to implement all of the methods defined in the interface definition.)
The other comment is that the safest way to handle characters() data is to use a StringBuilder/Buffer (StringBuilder is only valid in 5.0, StringBuffer has been around since Release 1.0) that you define in the startElement method. Use the append method to gather data presented to you in the characters() method and use toString() to harvest the data in the endElement method.

How to use SAX parser in J2ME

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.

Hi..
have a look at this.
