SAX parser retrieve attribute

Hi, I am parsing using the SAX Parser. In the XML excerpt below, how do I retrieve the "POL", "SUM" or "EUR" values?
If I use a contenthandler and I can extract the SubjectCode, Subject, and SubjectQualifier element names, but not the data contained within the attributes.
Thanks in advance fo rthe help...
<SubjectCode>
 <Subject FormalName="POL"/>
 <SubjectQualifier FormalName="SUBJECT"/>
 <Subject FormalName="SUM"/>
 <SubjectQualifier FormalName="SUBJECT"/>
 <Subject FormalName="EUR"/>
 <SubjectQualifier FormalName="SUBJECT"/>
 <Subject FormalName="GER"/>
 <SubjectQualifier FormalName="COUNTRY"/>
 <Subject FormalName="ITA"/>
 <SubjectQualifier FormalName="COUNTRY"/>
 <Subject FormalName="USA"/>
 <SubjectQualifier FormalName="COUNTRY"/>
</SubjectCode>

Something like this:public void startElement(String uri, String localName, String qName, Attributes attributes) {
if (localName.equals("Subject")) {
String formalName = attributes.getValue("FormalName");
// do something with that string
// and so on
}

Question on SAX Parser: retrieving child

Hi,
I am using SAX parser to parse the XML file, because the XML file size are huge. But here i need to retrieve the child nodes of the element. Is it possible with SAX parser to retrieve the child nodes? (Like DOM parser getChildNodes method)
Thanks in advance.

No, of course not. When you use SAX you write the code that stores the information. So if you need the child nodes, then write code that collects all child nodes.

Error processing request in sax parser No 'action' attribute found in XML

Hi All,
 I am doing a FILE to JDBC Scenario. I just want to send a data from file to Sql Db table. For this I have written a stored procedure to insert the row in a table.
This is the message mapping for FILE to JDBC .

Statement is mapped with FILESENDER_MT
action attribute is mapped with "EXECUTE" Constant
No is mapped with NO
Name is mapped with Name
for both isInput is mapped with TRUE
for both type is mapped with CHAR
Here is the my stored procedure.....

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 deal with empty tags in a SAX Parser

Hi,
I hope someone can help me with the problem I am having!
Basically, I have written an xml-editor application. When an XML file is selected, I parse the file with a SAX parser and save the start and end locations of all the tags and character data. This enables me to display the xml file with the tags all nicely formatted with pretty colours. Truly it is a Joy To Behold. However, I have a problem with tags in this form:
<package name="boo"/>
because the SAX parser treats them like this:
<package name = boo>
</package>
for various complex reasons the latter is unaccetable so my question is: Is there some fiendishly clever method to detect tags of this type as they occur, so that I can treat them accordingly?
Thanks,
Chris

I have spent some time on googling for code doing this, but found nothing better, than I had to write in by myself.
So, it would be something like this. Enjoy :)

XML - SAX Parsing Question

Hi,
I am parsing XML using SAX parser and fill the values into the HashTable ( like Key value pair ).. so i can get the vaues for a particular key using hash get function.
For the following XML. There are 2 "subscriberNumber" attribute, one is under "sn:Subscriber" and the another is under "sn:SubscriberChange".
I can able to put this values in hash table and when i print the Hash table it is printing as sn:subscriberNumber=[1234567890, 1234567890] .. But how will i know which one is from "sn:Subscriber" and which is from "sn:SubscriberChange"
This is the XML :
<sn:SubscriberNotification>
<sn:notificationSubType>1120</sn:notificationSubType>
<sn:Subscriber>
 <cng:PaymentType>PostPaid</cng:PaymentType>
 <sn:subscriberNumber>1234567890</sn:subscriberNumber>
</sn:Subscriber>
<sn:SubscriberChange>
 <sn:subscriberNumber>1234567890</sn:subscriberNumber>
</sn:SubscriberChange>
</sn:SubscriberNotification>
Any suggestion and pointers are really helpful
Thanks,
-Raj..

Try something like this:
import java.util.Stack;
import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;
class MyHandler extends DefaultHandler {
 Stack openTags = new Stack();
 public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
 if (qName.equals("sn:subscriberNumber")) {
 String parentTag = (String)openTags.peek();
 System.out.println("Parent tag of this <sn:subscriberNumber> is : <" + parentTag + ">");
 openTags.push(qName);
 public void endElement(String uri, String localName, String qName) throws SAXException {
 openTags.pop();

} My question is: I have taken my SQL query generated by toSQL() method in events and it worked.
Here is the funny thing:
Everything is correct syntax wise: No complaints what soever
The mysql part works: Tested separately.
So I tend to think that the problem lies within the SAX parser. I have written SAX2 parsers on this machine before and they have worked too. I tried inserting println statements all over startElement endElement etc etc only to find out that the SAX parser did not call any of the methods that I overided!! Why is that so?
Can you guys spot where my SAX parser fails?

I see.
I try to correct this problem by removing super();
so right now my code looks like this:
 static Event temp = new Event(0, 0, "null", "null", new Date(), 0, "null", 0);
 static String CurrentElement = null;
 static File XMLpath;
 static Connection db_connection;
 static XMLReader xr;
 static DefaultHandler XMLSAXhandler;
 //Constructor, Build the SAX Parser
 public EventXMLParser(File path, Connection connection) {
 try {
 this.XMLpath = path;
 this.db_connection = connection;
 this.xr = XMLReaderFactory.createXMLReader();
 this.XMLSAXhandler = new DefaultHandler(); //create a new own handler
 this.xr.setContentHandler(XMLSAXhandler);
 this.xr.setErrorHandler(XMLSAXhandler);
 //System.out.println("DEBUG: db_connection is " + db_connection.toString());
 catch (Exception e) {
 System.out.println("Constructor Error!");
 e.printStackTrace();
 }This time, I created a new instance of default handler() which can be referenced by as the objects's XMLSAXhandler. However, that did not solve the problem, why does the problem still persist?
Right now, there is only one instance of a default handler created. So why does all my parsing event functions still get ignored?

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
Kaushik

Hi,
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();

Sax parser problem

hi,
i am assuming the problem is with sax parser but i cant be sure. I am parsing a xml file (about 1.4MB) with some data in it. the parser i have created reads the xml file correctly for the most part but when at some point the
"public void characters(char buf[], int offset, int len) throws SAXException"
function stops working correctly....i.e it doesnt fully read read the data between the "<start>" and "</start>" element. say it reads about 100 id's correctly---for 101 ID it does this. This is just an example. Since, the problem might be with how :
"public void characters(char buf[], int offset, int len) throws SAXException"
function is reading the data i was wondering if anybody else had encountered this problem or please let me know if i need to change something in the code: here's a part of the code :
Bascially i have created three classes to enter data into three mysql tables and as i parse the data i fill up the columns by matching the column header with the tagName.

I haven't gone through your code but I also had a similar error....and the exception in my was because of an "&" instead of the entity reference & in one of the element values. I use a non-validating parser but if you use a validating one then this might not be the reason for your exception.

JDBC receiver adapter - Error processing request in sax parser

Hello,
I want to INSERT idoc data via JDBC adapter into a MS SQL database. After digging through SAP Help, numerous blogs and forum discussions on SDN and even posting an OSS message I still get the same error:
'Error: TransformException error in xml processor class: Error processing request in sax parser: No 'action' attribute found in XML document (attribute "action" missing or wrong XML structure)'
When testing my mapping in the Integration Repository the resulting XML message is:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Employee xmlns:ns0="http://prodrive.nl/xi/HRMasterdata/HRMD_A_2_d_bcommerp">
 <STATEMENT>
 <T_PD_Employees action="INSERT">
 <access>
 <KeyTag>00088888</KeyTag>
 <PerNo>00088888</PerNo>
 </access>
 </T_PD_Employees>
 </STATEMENT>
</ns0:Employee>
The connection to the database is fine, Sender adapter with a SELECT * works perfect.
Can anyone help me solve this problem? I'm lost.
Best regards,
Roelof Jan Bouwknegt

Hi Bhavesh,
I have tried out the change you suggested. Without success. Message I get back is
- 2006-12-28 10:34:08 CET: Error: TransformException error in xml processor class: Error processing request in sax parser: No 'action' attribute found in XML document (attribute "action" missing or wrong XML structure)
structure in testtool:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Employee xmlns:ns0="http://prodrive.nl/xi/HRMasterdata/HRMD_A_2_d_bcommerp">
 <STATEMENT>
 <T_PD_Employees action="INSERT">
 <ACCESS>
 <KEYTAG>00088888</KEYTAG>
 <PERNO>00088888</PERNO>
 </ACCESS>
 </T_PD_Employees>
 </STATEMENT>
</ns0:Employee>
Somehow the SAX parser doesn't like the result of my mapping. Maybe there is something wrong with the structure cardinality. Let me describe what I have built:
XSD:
WA_T_PD_Employees - Complex Type
> STATEMENT - Element - Occurence = 1
>> T_PD_Employees - Element - Occurence = 1
>>> STATEMENT - Attribute - Occurence = optional
>>> access - Element - Occurence = 1..Unbounded
Best regards Roelof Jan and thanks for your quick response

How to get a specific tag value from SAX parser

I am using the SAX method to parse my xml file.
My Question is how to get the returning characters parsed after calling?
esp the value of <body> tag?
Here is my xml file, and i want to get the parsed <body> value after call sax parser.

Problem in using SAX parser.

Hai All,
I have got a problem in using SAX parser.
My XML looks like this:
<authorizer>
<first-name>HP</first-name>
<last-name>Services</last-name>
<phone>800-22-1984</phone>
</authorizer>
<destination>
<first-name>John</first-name>
<last-name>Doe</last-name>
<company>John Doe Enterprises, Inc.</company>
<department>Manufacturing</department>
<phone>800-555-1234</phone>
<address>
<street-one>1654 Peachtree Str</street-one>
<street-two>Suite Y</street-two>
<city>Atlanta</city>
<province>GA</province>
<country>US</country>
<postal-code>30326</postal-code>
</address>
</destination>
my part of SAX parser code is:
public void startElement (String name, AttributeList attrs)
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.
Pooja.

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;
}

Sax Parser for loading XML file

We have a requirment by which we need to load huge XMl file in our DB everyday.

This parser takes 2 hours to laod file of size around 8MB.
ANy suggestions on improving performance of the parser.
ANy other approach I should be taking to load this file into DB.
We are using ORacle 9i DB with Character set UTF 8.
Thanks!

String buf = (new String(ch, start, length)).trim();
if (thisElement != "root"){
if ((buf.length() == 0) && (thisElement !="") ){
It run ok!
Thanks 58871!
Now, i want to export oracle table to xml file like :
<?xml version="1.0" encoding="UTF-8"?>
<root>
<emp>
<ename>aaa</ename>
<sal>3000</sal>
</emp>
<emp>
<ename>bbb</ename>
<sal>5000</sal>
</emp>
</root>
Can SAX export to xml format?

SAX parser doesn't report IDREF type

I have been trying to create my first DTD:
<!ELEMENT Network (Node+, Link*)>
<!ELEMENT Node EMPTY>
<!ATTLIST Node
ID ID #REQUIRED
title CDATA #IMPLIED>
<!ELEMENT Link EMPTY>
<!ATTLIST Link
source IDREF #REQUIRED
dest IDREF #REQUIRED
title CDATA #IMPLIED>
and would expect that the source and dest attributes of the
Link element would have the type IDREF when being parsed with
the SAX parser. Using the SAXSample.java provided I get the
following output for a test network:
StartElement:Network
IgnorableWhiteSpace
StartElement:Node
ID(ID)=node1
title(CDATA)=test node
EndElement:Node
IgnorableWhiteSpace
StartElement:Node
ID(ID)=node2
title(CDATA)=another node
EndElement:Node
IgnorableWhiteSpace
StartElement:Link
source(CDATA)=node2
dest(CDATA)=node1
EndElement:Link
IgnorableWhiteSpace
StartElement:Link
source(CDATA)=node1
dest(CDATA)=node2
EndElement:Link
IgnorableWhiteSpace
EndElement:Network
This clearly shows source and dest reported as CDATA type. Not
exactly what's in the DTD.
Is this an undocumented feature (a.k.a. bug?)

Thanks for the replies, but I don't think we are quite connecting. I do eventually want to be able to validate an XML file against a schema (which I can't do either), but first I want to be able to validate the schema file itself; i.e. to confirm that the schema I designed is a valid schema file. As I understand it, it should be possible to tell the parser that the schema to validate against is the "schema for writing schemas", http://www.w3.org/Schema/schema.xsd (or whatever it is). That's where I'm getting stuck, that the parser doesn't recognize the elements for actually defining a schema.

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.
