Generating XMLs from CSVs using DOM parser......

Hi,
I am trying to generate XMLs from CSV files using DOM parser. XMLs are getting generated but the problem is that i am using Encoding "ISO-8859-1" but XMLs are getting generated in UTF-8 encoding.
Please refer to the code below and advice. (where are the code tags gone ????? )
Source domSource = new DOMSource(document);
ByteArrayOutputStream xmlStream = new ByteArrayOutputStream();
Result result = new StreamResult(xmlStream);
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.transform(domSource, result);
xmlStream.close();
generatedXml = new String(xmlStream.toByteArray(), "*ISO-8859-1*");

Use transformer.setOutputProperty(OutputKeys.ENCODING, "ISO-8859-1") to specify the character set.

Can't parse xml from applet using dom on linux on Netscape 7 using jre 1.4.

Hi,
I can't seem to parse xml from an applet on linux on Netscape 7 using the JRE 1.4.
My code looks like the following:
StringBufferInputStream is = new StringBufferInputStream("<foo></foo>");
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = null;
try
  builder = factory.newDocumentBuilder();
  domDocument = builder.parse(is); // this line creates an exception
catch (Exception e)
  System.out.println(e);
This code works fine from an applet on windows. On linux, the error message is:
java.security.AccessControlException: access denied (java.util.PropertyPermission entityExpansionLimit read)
I've tried both JRE 1.4.0_04 and 1.4.1_03
Thanks!
Q

There's another posting about this same problem (platform unspecified), but the same error message. I was also having this problem (Windows 1.4.03) and swithced back to 1.4.01 and the problem went away. In the future, I may sign my applets to get a more generous security policy. But, I'm sure it'll be a lot of work (vs. a line of code somewhere).

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.

Generating XML from Database using XSQL

Hi ,
I have been using Reports as an intermidiate to generate XML (by giving concurrent program o/p type as XML). Now, i want it to be done from SQL or PL/SQL. I am able to achieve this using XSQL functions. I placed the SQL in a .sql file and registered it as a concurrent program. It was giving me XML output.
I have two problems here.
1. How can i know whether i have generated valid xml or not?
2. When i am linking this concurrent program to XML Publisher, publisher is not able to read thie output from the concurrent prograam. It is erroring out. Why?
Thanks
sap

Save the XML file - try to open it with IE and/or Firefox.
If that doesn't work you know already something is wrong.
You may try to cut&paste it into notepad and save as UTF-8.
Then try it out with the Template Builder for Wrod.
If you can't figure it out and run the report with a SMALL dataset six (ie. 1)
and post it here.

Updating XML file using DOM parser

Hi,
Can someone help me, how to update following XML file using DOM parser.
The following is my XML file.
<students>
     <student>
          <id>1</id>
          <name>abc</name>
     </student>
     <student>
          <id>2</id>
          <name>xyz</name>
     </student>
     <student>
          <id>3</id>
          <name/>
     </student>
     <student>
          <id>4</id>
          <name>ijk</name>
     </student>
     <student>
          <id>5</id>
          <name></name>
     </student>
</students>Consider, I will input 2 fields, ie., id & name. For the matching Id, the name has to be updated.
Though, I have achieved this, but I am unable to update the value for 3rd record, & 5th record ie., id=3 & id=5. Since, these are blank.
Thanks.

Some <name> elements have a child node which is a text node. From what you say it appears you know how to change those text nodes.
The other <name> elements don't have any child nodes. But you want one. This suggests to me that you need code that creates a text node and adds it to the <name> element as its child.

Problem in parsing XML using DOM Parser.

Hi,
I am parsing an XML using DOM Parser.
When i try to get attributes of a node, i dont get in the order it is written. For Eg. This the node:
<Level0 label="News" link="/website/ing_news.nsf/ViewNewsForm?OpenForm&All" level="202" uid="COGN-4MNMT3" parentid="aaaa">
When i try to print the attribute values i should get in the order:
News, /website/ing_news.nsf/ViewNewsForm?OpenForm&All, 202, COGN-4MNMT3, aaaa
BUT I AM GETTING IN THE ORDER:
News, 202, /website/ing_news.nsf/ViewNewsForm?OpenForm&All, aaaa, COGN-4MNMT3
Is there any way to sort this problem out?
Thanks and Regards,
Ashok

Hi Guys,
Thanks a lot for your replies.
But i want to keep all the values as attributes only.
the XML file is as shown below:
<Menu>
<Level0 label="News" link="/website/ing_news.nsf/ViewNewsForm?OpenForm&All" level="202" uid="COGN-4MNMT3" parentid="aaaa" children="3">
     <Level1 label="ING News" link="" level="1" uid="COGN-4MNN89" parentid="COGN-4MNMT3" children="3" >
          <Level2 label="All ING News" link="/website/ing_news.nsf/ViewNewsForm?OpenForm&All" level="2" uid="INGD-4MVTK2" parentid="COGN-4MNN89" children="0">
          </Level2>
</Level1>
</Level0>
The code i was using to get attributes is:
String strElementName = new String(node.getNodeName());
     // System.out.println("strElementName:"+node.getNodeName());
NamedNodeMap attrs = node.getAttributes();
if (attrs != null) {
int iLength = attrs.getLength();
for (int i = 0; i < iLength; i++) {
String strAttributes = (String) attrs.item(i).getNodeName();
String strValues = (String) attrs.item(i).getNodeValue();
Also is it not possible to Enforce the order using some Schema/DTD in this case?
TIA
Ashok

Parsing an XML using DOM parser in Java in Recursive fashion

I need to parse an XML using DOM parser in Java. New tags can be added to the XML in future. Code should be written in such a way that even with new tags added there should not be any code change. I felt that parsing the XML recursively can solve this problem. Can any one please share sample Java code that parses XML recursively. Thanks in Advance.

Actually, if you are planning to use DOM then you will be doing that task after you parse the data. But anyway, have you read any tutorials or books about how to process XML in Java? If not, my suggestion would be to start by doing that. You cannot learn that by fishing on forums. Try this one for example:

Parsing xml using DOM parser in java

hi there!!!
i don have much idea about parsing xml.. i have an xml file which consists of details regarding indentation and spacing standards of C lang.. i need to read the file using DOM parser in java n store each of the attributes n elements in some data structure in java..
need help as soon as possible!!!

DOM is the easiest way to parse XML document, google for JDOM example it is very easy to implement.
you need to know what is attribute, what is text content and what is Value in XML then easily you can parse your document with dom (watch for space[text#] in your XML document when you parse it).
you get root node then nodelist of childs for root then go further inside, it is easy believe me.

How to manipulate object mapping runtime using DOM parser in java?

Scenario: We will be getting logical name of the table from which we have to fetch the details. We have few tables which have more or less same columns, the only difference is the prefix. Say we have Tables: Temp1 and Temp2 contains column as Temp1Col1 and Temp2Col1. I dont want to go with creating as many POJO classes in java as that of tables. So i will create only one POJO class with common attributes and at runtime i want to change the object mapping file of Hibernate to hold table values. I have an idea that this can be done using DOM parser. But it would be great if somebody can share the java code for the same.
Thanks in advance.

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.

Generating XML from SQL queries and saving to a xml file?

Hi there,
I was wondering if somebody could help with regards to the following:
Generating XML from SQL queries and saving to a xml file?
We want to have a stored procedure(PL/SQL) that accepts an order number as an input parameter(the procedure
is accessed by our software on the client machine).
Using this order number we do a couple of SQL queries.
My first question: What would be our best option to convert the result of the
queries to xml?
Second Question: Once the XML has been generated, how do we save that XML to a file?
(The XML file is going to be saved on the file system of the server that
the database is running on.)
Now our procedure will also have a output parameter which returns the filename to us. eg. Order1001.xml
Our software on the client machine will then ftp this XML file(based on the output parameter[filename]) to
the client hard drive.
Any information would be greatly appreciated.
Thanking you,
Francois

Generate xml from db

Hi all,
Does anyone has a good suggestion on how to generate an xml doc dynamically from db without using XSU?
null

Hi,
We would like to get some more info from you regarding the performance issues. What are you trying to do exactly? i.e. generate XML as a string, DOM, SAX, lob etc..? are you trying to use XSL-t after that?
Also, where are you running the XSU (inside the database, from a webserver etc..)
We might be able to provide you with better answers if you can give us any other benchmarks that you ran etc..
Thanks,

Generating XML from database

I'm a total newbie in XML DB and need advice on generating XML from database.
The situation is the following: there is a legacy web application which uses an XML document as a configuration file. This document conforms to some well-defined schema. For instance:
<config>
     <title value="TITLE" />
     <subtitle value="SUBTITLE" />
     <style url="default.css" />
     <widgets>
          <widget id="1" opened="true" />
          <widget id="2" opened="false" />
     </widgets>
</config>
It contains portions of static data which are common for all users as well as dynamic personal data.
Dynamic data comes from two sources:
1) security considerations (for instance, not all widgets are available for some users) - thus the "master" configuration content must be filtered, but not otherwise modified;
2) user preferences (for instance, user can set widget2 to be opened by default) - thus values of some attributes must be different for each user. When the user saves her preferences, the entire document with new values is posted back to server.
We want to try to store user preferences, apply security and generate personalized configuration documents using XML DB.
So we need advice on storage models and generation procedures - which should be more efficient and easy to support or extend.
Please note, that there is no requirement to actually store data as XML.
Thanks in advance!
P.S.: Sorry for the incomplete initial post.

How to parse using DOM parser:

<employee>
     <name>phaneendra</name>
     <age>21</age>
     <company>ABC</company>
     <Authorization>
          <ID>21<ID>
          <Role>Normal</Role>
     </Authorization>
</employee>
I am using DOM Parser.Using that parser how can i wil get the <Authorization> node value as
<Authorization>
     <ID>21<ID>
     <Role>Normal</Role>
</Authorization>
thanks in advance

Since you seem new to using DOM, I'll first give a word of advice.
Get very familiar with the JavaDocs for things like Document, Element, Node and Attribute. There is much wisdom in those files, especially in the table near the top of the Node interface. Pay particular attention to the meaning of nodeValue for various types on content.
Using DOM, you get a Document.
From a Document, you can use the getDocumentElement to get the root element (in your case, the one with a name of "employee").
From an Element, to get to a child Element with a specific name, use getElementsByTagName or getElementsByTagNameNS (if your elements are coded with NameSpaces).
Then get the first entry in the resulting list and process it however you like.
