SAX Parser quick question
When you are parsing a file using the Sax do you have to set validation method on both the factory and the parse for it validate that the file is well formed XML?
saxParserFactory.isValidating(true);
saxParser.isValidating(true);
Thanks
no. setting it on the factory will create parsers with that setting already set to true.

Hi All,
I get an xml file by making an http request. The name of the DTD comes as a relative path in the response xml file.
Questions
1. Is there a way to handle this
2. I read somewhere that i could avoid looking at the DTD alltogether,
can someone show me how with a sample code.
Kind regardsNothing seems to help, Please help,
Im using jdk1.4 A full source codee would be great.

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,

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.

Hi All,
Any help is appreciated. Is it possible to start parsing an XML document somewhere in the middle of the document using SAX parser? It will still parse the doc sequentially but has to start at a specified location or sorts instead of starting from the beginning.
Thanks in advance.Sure. Open an InputStream on the document (a FileInputStream or whatever is convenient). Read the part of the InputStream before the document and ignore the data. When you have the InputStream's cursor pointing at the beginning of the document, pass it to the parser.

I have a program that parses an XML document using a SAX parser. It reads the XML files that are in a given directory /home/user/input. So if there are three files it will parse the files in order, one at a time. I want it to process multiple files at the same time.
Current it�s
Public class ProcessFile extends DefaultHandler
How could I use Thread since I�m extending DefualtHandler for the parser?SAX should mask the fact that some content is specified inside of a CDATA section.. It is just characters.
The safest way to process characters is to setup a StringBuffer or equivalent in the startElement method. There is a variation of the StringBuffer append method that has the same three parameters (char[], int, int) as the characters signature. The characters method may be called many times before you are given all of the content of the string. How it decides when to call you depends on the parser and is subject to change over time. But, if you accumulate the contents in each call of characters and do the toString() in the endElement method you are going to get the right content. Lots of people over the last year or so that I've been involved in this forum have had other ways they thought were better than this, but most of them have eventually tried and accepted this way because it works and their "better" way did not.
It looks like you got the content for the CDATA section (Please refer...).I'm not sure what your problem is.

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,
ChrisI 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 :)

} 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? -
I am using the sax parser provided by the package javax.xml.parsers to parse an XML file. It works fine as long as I have an XML file which has English characters. When I use it for parsing a file which has Korean characters in it, the parser fails to recognize them.
It used to throw an error "Line too long" on reading the Korean characters. Then I added an XML directive encoding="EUC-KR" and now it reads the file but does not recognize the characters correctly. It reads all the korean characters as question marks ('??').
Any pointers on what can be done to fix this problem.
Thanks,
RahulJHi,
We've got a very similar problem. I'm parsing with SAX and DOM but the MS special characters keep appearing as ? or ??.
If the encoding is not specified in the XML file there are Parser Exceptions. If I set the encoding to "JISAutoDetect", "JIS", "MS932", "Cp1250 to Cp1258" or "ISO8859-1" then there are no exceptions but the stray characters still appear as ?s.
I managed to display the left and the right quotation marks in a servlet by setting the response Content Type to "text/html; charset=Shift_JIS" and the encoding="Cp1252" in the XML file. But I still have problems with the rest of the characters.
What kind of output do you use? Do you display in a web page or you just write to a file?
Thanks,
Ross -
As I reported in this thread: Carriage Returns in XSLT output I am trying to produce a text output file with each line terminating in cr-lf (using the output from ViewObject.writeXML() passed through the XSLProcessor.processXSL() method to apply a XSLT stylesheet transformation to it), but the cr characters in the stylesheet are being converted to nl characters, so I am ending up with two nl characters at the end of each line.
I found a 2002 query (here: http://www.xslt.com/html/xsl-list/2002-04/msg00193.html) by someone with the same problem, and a reply by Steve Muench explaining it and stating that the Oracle SAX parser does not have the same problem.
So my question now is - does the SAX parser still retain cr characters (or is it too now converting them to nl) and if it does, how do I make XSLProcessor.processXSL() use it rather than the default XML parser? Can I do it from within my code, or does it need to be set in some sort of environment variable? We are on version 9.0.5.2 of JDeveloper(10g)Repost

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">

<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 BouwknegtHi Bhavesh,
I have tried out the change you suggested. Without success. Message I get back is

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:

SAX parser splits up character data; I expected Ign. whitesp
Im am working on a XML parser for loading data from some back
end systems into an Oracle 8i database. I am using the SAX
parser for this purpose. After doing some tests with larger
amounts of XML data (> 1M), I found some unexpected behaviour.
The parser sometimes splits up character data into two chunks of
data. The XML looks as follows:
<TAGNAME> this is the character data </TAGNAME>
The parser raises the following events:
1 startElement name = "TAGNAME"
2 characters chbuf = " "
3 characters chbuf = "this is the character data "
4 endElement name = "TAGNAME"
I expected an ignorableWhitespace event at step 2. The XML
document contains repetitive tagnames. The strange thing about
the parse process is that the parser splits up the character
data only sometimes, and I can't determine any kind of logica
for this behaviour. Most occurrences of exactly the same tagname
and character data are parsed correctly (that is, as I
expected).
Am I dealing with correct behaviour here, or is it a bug??

Thank you for your quick response.
In my test XML, there are about 27500 tags containing character
data. All character data starts with a whitespace character.
After parsing the xml, the whitespace of only 5 (!) tags is
treated as a seperate character event (so two character events
are raised in succession). The remaining tags all raise only ONE
character event for the entire character data. I can't explain
the difference in treatment.

hi,
i want to kow from which version jdk release sax parser is being supported.

acXML APIs were added in Java 1.4.You could have saved you the time by checking the other threads. The question had already been answered, and that's why I just hate cross-posters.
