JAXP: Write formatted XML to a file? Tabs?

I've built an XML document (org.w3c.dom.Document) and I want to write a formatted version of that to a file.
Currently, I'm doing the following, but it doesn't do indentation at all.
          TransformerFactory tf = TransformerFactory.newInstance();
          Transformer t = tf.newTransformer();
          t.setOutputProperty(OutputKeys.INDENT, "yes");
          FileOutputStream fileStream = new FileOutputStream(file);
          try {
               t.transform(new DOMSource(document), new StreamResult(fileStream));
          } finally {
               fileStream.close();
What do I need to change?
Thanks!

Hi Tony!
I took a long weekend so I'm just now getting back to my problem!
I'm still struggling with getting html markup to display in a PDF report. I have the html content in a clob (and n_clob - I tried both) field and TIDY was run on the data before inserting into the database (so it's well-formed). The problem appears when APEX creates the .xml file...the angled brackets are escaped (and I understand why this is necessary) but when I use an .xsl doc to transform the escaped characters back to angled brackets, it works, but all I get is text, not the html output (tables).
I played around with the .xml file and did a search for & lt; and & gt; characters and replaced them with the less than/greater than characters, then ran it through BI Publisher with the .xsl file and the html tables show up perfectly. Also, my bold or italics tags only work if I do the search/replace on those characters.
So if I could create an .xml file myself (which would contain html tags in their unescaped state) and pass that to BIP, I am hoping this solves the problem.
Are you sorry you asked now? :)

Format XML data when writing to a file

Hi,
I am trying to write runtime data (XML) to a file. I am doign the following to write to the file:
public void saveFile() throws Exception {
try {
TransformerFactory transformerFactory =
TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(doc);
OutputStream output = new FileOutputStream(XMLFile);
StreamResult result = new StreamResult();
transformer.transform(source, result);
output.flush();
output.close();
} catch (Exception x) {
throw x;
The output from the above code is a clutter of elements. All the elements are on the same line some times.
1) How can I format the output? (Indent the elements in the file)
Is there a way to achieve this?
Sometimes, I see a square character at the end of some lines. I thought the output file is corrupt because of this character. But it does not seem to be a problem.
2) How do I avoid this character?

Also, I am planning on using xpath in conjunction with DOM. However I read on one of the websites not to use too many xpath queries. I am using jdk 1.5.
Is it tight. My code might have to be run many times. Is the following ok?
or should I eliminate xpath and do my own traversing. I am concerned about runtime performance if I have to continue to update the xml file frequently.
public Element getMatchingNode(MyAttributes attr) throws Exception {
try {
File myFile = new File(XMLFile);
if (myFile.exists()) {
System.out.println(XMLFile + " File exists");
XPathFactory factory = XPathFactory.newInstance();
XPath xPath = factory.newXPath();
InputSource inputSource =
new InputSource(new FileInputStream(myFile));
String matchingString = this.getMatchingString(attr);
Element module =
(Element)xPath.evaluate("/" + TEST_TAG +
"/" +
TEST_TAG2 +
"/" +
DETAIL +
matchingString,
inputSource,
XPathConstants.NODE);
return module;
} else
return null;
} catch (Exception x) {
throw x;
private String getMatchingString(MyAttributes attrs){
StringBuffer buffer = new StringBuffer();
for (Enumeration e=attrs.keys(); e.hasMoreElements();){
String attribute = (String)e.nextElement();
String value = attrs.get(attribute);
buffer.append("[@" + attribute + "=" + "'" + value + "']");
return buffer.toString();
}

OSB XML to Flat file(write)- MFL?

Hi,
OSB 11G
I will be invoking the db to get XML data and I have to write to a text file(pipe delimiter).
I saw below forum, but I am not sure how to create MFL .Can you anyone pls mention the steps. (MFL ->XML to flat file )
Do I have import xsd in Native Builder and convert to a flat file with pipe delimiter ?
How to write a CSV file in OSB
Thanks
Edited by: soauser on Jul 7, 2011 8:07 PM

truth must be said, MFL is very sensitive to input data, any deviation from the contract is punished with a NullPointerException, especially when the input is in binary format. One would expect a better error message, but what can we do.
Make sure your input data complies with the Schema, for instance do a xsd validation...

How to write non-XML data to a file using an OSB FTP Routing?

Hi --
Situation ... I need to write non-XML data to a file using FTP. A proxy service retrieves XML and transforms it with XSLT to CSV format, then gives it to a Biz service to file it out, using FTP. Simple.
Problem ... OSB sends the contents of $body to any service it calls. Because $body is a SOAP document, it has to contain XML. So therefore I have to put my CSV data into an XML element, in order to put it into $body; and this inner element then gets written to the file, which I don’t want. But if I don't enclose my CSV content in a tag, I get "Unexpected CDATA encountered" trying to assign it to a variable.
There has to be away around this!
Thanks for your help.
John Taylor

Solved. Steps:
-- Transform the XML to CSV using an XSL transform. Put the CSV data inside enclosing XML elements, and use a Replace action to put the XML element + CSV contents back into *$body*.
-- Define an MFL transform that only knows about the enclosing XML elements. Use a delimiter of "\n" (hard return).
-- Route from the proxy service to a Biz service that has Service Type = Messaging Service and Request Message Type = MFL; specify the MFL transform, which will receive the incoming *$body* variable, strip off the enclosing XML element within it, and pass the CSV contents to the FTP service.

Now , am not a very good Java DEv. and i need to find a soln. to this prob within 1 week.
The next step is to write the data to the DB.
Am sending an example of my file:

Note that i can have more than 1 machines (meaning that i have to loop thru the file to be able to write to the DB)
Cal u tellme what to do!
Even better- do u have a piece of code that will help me understand and implement the database writing portion?
I badly need help here.

how can I write a XML file, that has a reference to a DTD like:
<!DOCTYPE testdoc SYSTEM "testdoc.dtd">
I have a DOM that contains my XML-Data and I want to have this line in the XML File. I'm using a Transformer to write this XML stuff in the file.
Does anyone has an idea?

outf.flush();

Hi,
when I look in the JDK1.4.2 specification I don't see any write method in the Document interface.
However, your solution is the Transformer class. There you transform your DOM tree into any output you need. Your code sould look something like this:     TransformerFactory tf = TransformerFactory.newInstance();
     // set all necessary features for your transformer -> see OutputKeys
     Transformer t = tf.newTransformer();
     t.transform(new DOMSource(xmlDoc), new StreamResult(file));Then you have your XML file stored in the file system.
Hope it helps.

How to write a Xml installation file to build web installer using IzPack.

Hi,
that is not really a java related question. Have you tried to find some IzPack support forum? I've never heard about it, so I can't help.

Using a CWM format XML as datastore; COM SDK to read the file and create Universe

Hello everyone
We are in the process of migrating from a metadata store to BusinessObjects Universe and the plan is to use Java/COM SDK to accomplish that. We have run into limitations with both the SDKs. Java SDK doesn't provide that facility and using COM SDK we are trying to read from a XML file (metadata in CWM format) and create the universe but so far haven't been successful. If the (Universe)Designer can read a CWM format xml file (say created from BODS) we are wondering why can't a customer made COM program do the same.
Has anyone attempted this and been successful. Please acknowledge.
Thanks

I have written C#.NET code to build universes on the fly using the Designer SDK with no problems. However, I wasn't using CWM formatted data to do this.
I have two suggestions for you:
1. Since not all of the functionality in the Designer tool seems to be available through the SDK, can you parse the CWM xml file in your code and build the universe based on the data instead of trying have Designer build it?
2. Since you're using Java, you may get better answers by posting this question in the Java SDK Application Development space here: http://scn.sap.com/community/bi-platform/java-sdk

How to write a XML Document to the current filesystem using JAVA....

Document xmlDoc;

Have you considered using JDOM? ( www.jdom.org )
The XMLOutputter class can write the Document to a file. ( The Document however will be an org.jdom.Document object ).
If you are weary of a new API, you could just create a new File object called abc.xml and stream the data from the XML Document you have to this new File object.

How Do I write an XML file using Java?

Hello there!! to everyone reading my post.
I have this project I need to do, and I have no clue where to start, I was wondering if you guys could help me out.
I need to know how to write an XML file using a Java Program, but without using a Third party library.... just using java native APIs.
I will probably take the values to construct the file from a form.
I will certainly appreciate if you could post some sample code for me.
Thank you very much in advance..

Hello there!,
I have some doubts about the Tutorial I am currently reading. correct me If I'm wrong, but the section "Write a simple XML file" teaches you how to do so using a text editor. I need to create my XML file from a running Java Program written by myself, that takes the values to build it from some variables.
If I'm totally wrong about what I'm saying, could you please point me to where I can find the information of how to do what I'm asking for, inside the tutorial.
Thank you very much,...
sincerely.

Write to XML File crashes when multiple Timed Loops present

Hello All,
It took me forever to track this bug down.
In this project we can edit operating parameters on the Host and send them down to an RT program in a cRIO-9025. The data is converted to XML and stored on the cRIO's disk.
Occasionally, the RT program would lock up and had to be rebooted.
It turns out that if you use Timed Loops , then a Write to XML File (or presumably any file write) will not return.
Attached is an example. This has 5 loops to make it crash faster, but it will eventually crash with only 2.

XML Write test.vi ‏93 KB

Hello Chris,
I know that Write to XML File fails because I put in debug code in my actual program, a flat sequence which updated an indicator, and after the crash, the indicator had not updated.
Yes, I know that it replaces the file. It's a configuration file, not data gathering. This is just an example of the bug.
FYI,
I increased the period for the loop with the file save to 500msecs and it still crashed.
I then decreased it to 50 msecs, and replaced all of the other Timed loops with While loops and it does not crash, even though the file save takes much longer than 50 msecs, average ~150msecs.
I replaced the loop with the file save with a While loop while leaving the others as Timed loops and it does not crash.
So the bug is systemic and related to a file save in a Timed Loop when there are other Timed Loops.
I'm not looking for a solution, I'm only reporting a bug in Labview. The solution is not to use Timed Loops, especially, as you point out, when there is file saving. It cost me several days of dicking around to figure it out. Maybe someone can save some time if they find this.
