Multi heirarchy DOM tree using XSU ???

I'm not able to retrieve a A-->b-->C-->D-->E heirarchy representation of XML data(String or DOM)
My Data base is in terms of simple tables so when I try to use simple OracleXMLQquey I'm not able to secure my objective...
I wud appreciate if anybody can send me an example code to derive multi level DOM tree using XSU API's

Use the CURSOR() operator, or object views to accomplish your goal.
See the release notes for the XSQL Servlet for some hints in this area.
My soon-to-be released book, "Building Oracle XML Applications" from O'Reilly has many additional examples of using these techniques.

XML Parser for Java v2. Applying XSLT to DOM tree

I encountered pretty weird behavior of XML Parser for Java v2.
While applying XSLT to XML document created in memory using DOM
interface I couldn't access element attributes. For example,
given the XML document:
<root>
<Item ID="00001">Value of Item 00001</Item>
<Item ID="00002">Value of Item 00002</Item>
</root>
and XSLT:
<xsl:template match="/">
<HTML>
<HEAD>
<TITLE>XSLT Test</TITLE>
</HEAD>
<BODY>
<xsl:for-each select="/Error">
<H1>Error</H1><xsl:value-of select="."/>
</xsl:for-each>
<TABLE border="0" cellspacing="0" cellpadding="2">
<TBODY>
<xsl:for-each select="/root">
<TR>
<TH style="background-color:khaki">
<xsl:text>Attribute</xsl:text>
</TH>
<TH style="background-color:khaki">
<xsl:text>Value</xsl:text>
</TH>
</TR>
<xsl:for-each select="Item">
<TR>
<TD><xsl:value-of select="@ID"/></TD>
<TD><xsl:value-of select="."/></TD>
</TR>
</xsl:for-each>
</xsl:for-each>
</TBODY>
</TABLE>
</BODY>
</HTML>
</xsl:template>
If I build DOM tree by parsing XML file the resulting HTML
document after applying XSLT will display
Attribute Value
00001 Value of Item 00001
00002 Value of Item 00002
But if I build DOM tree using following code:
XMLDocument xDoc = new XMLDocument();
Element root = xDoc.createElement( "root" );
xDoc.appendChild( root );
Element elem = xDoc.createElement( "Item" );
elem.setAttribute( "ID", "00001" );
root.appendChild( elem ).
appendChild( xDoc.createTextNode( "Value of Item 00001" ) );
elem = xDoc.createElement( "Item" );
elem.setAttribute( "ID", "00002" );
root.appendChild( elem )
.appendChild( xDoc.createTextNode( "Value of Item 00002" ) );
the same XSLT will produce the following HTML output:
Attribute Value
Value of Item 00001
Value of Item 00002
So the value for the ID attribute is not displayed. At the same
time I can access this attribute using DOM interface. For
example, following code
NodeList nList = xDoc.getElementsByTagName( "Item" );
Element e;
for( int i = 0; i < nList.getLength(); i++ )
e = (Element)nList.item( i );
System.out.println( "ID: " + e.getAttribute( "ID" ) );
produces an output
ID: 00001
ID: 00002
Here is the code for applying XSLT to DOM tree:
DOMParser parser = new DOMParser();
parser.parse( new FileInputStream( "test.xsl" ) );
XMLDocument xsldoc = parser.getDocument();
XSLStylesheet xsl = new XSLStylesheet( xsldoc, createURL( "" ) );
XMLDocument out = new XMLDocument();
out.appendChild( new XSLProcessor().processXSL(xsl, xDoc) );
out.print( new FileOutputStream( "test.html" ) );

Generating XML from DOM tree

Hello,
I am trying to generate a XML file from a DOM tree. This facility is there in IBM parser.
But anyone can help me out in generating a XML file or string from a DOM tree using the Crimson parser provided by default in JDK 1.4.0
Thank you

The only way I know is to use JDOM (which provides a output package).
You can build a JDOM tree starting from your DOM tree, and then output this JDOM tree in an XML file.
Hope it will help.

How to Recursively traverse a Dom Tree

Use this: DomRead.java at your own risk. caveat: this gets screwed up if the attributes are multi-valued. You can use XPath to get around that. I am struggling with the proper XPath expressions.

Applescript Help: Search for text in Safari DOM tree

Im trying to make a script really similar what was asked here: Re: Find text in webpage and email notification applescript/automator Except instead of searching the "source code" of the page, I want the script to search the "DOM tree" for the page.
To summarize, I am trying to make a script that loads a safari page, searches for a particular text in the DOM Tree, and if found will send me an email.
Here is the code from the other thread I referenced:
on idle
          set pagURL to "http://page.url.com?whatever"
          if application "Safari" is not running then
                    quit
                    return
          end if
          tell application "Safari"
                    set URL of document 1 of window 1 to "http://your.web.address/"
                    delay 5
-- delay to let page load.
                    if source of document 1 of window 1 contains "search text" then
                              my sendAMail()
                    end if
                    return 900 --fifteen minutes
          end tell
end idle
on sendAMail()
          tell application "Mail"
                    set theMess to make new outgoing message at end with properties {sender:"your name", subject:"some subject line", content:"The message you want to send to yourself", visible:true}
                    tell theMess
                               make new to recipient at end of to recipients with properties {address:"[email protected]"}
                    end tell
-- send theMess
          end tell
end sendAMail
Any help would be appreciated!

For the URL you quote as an example (http://www.sislands.com/coin70/week2/NestedLoops1.htm), using text instead of source worked for me:
if text of document 1 of window 1 contains "1 2 3 4" then
another example:
if text of document 1 of window 1 contains "10 12 14 16" then
Note a double space between single digits (1 2 3 4) and a single space between double digits (10 12 14 16) is required for a match as per the table format:
Any full line:
if text of document 1 of window 1 contains "for (i = 1; i <= 10; i++) { // when i = 10" then
or partial line works:
if text of document 1 of window 1 contains "; i++) { // when i = 10" then

Help with creating a new XML file from an existing DOM tree!!

i want to create a new XML file from an existing DOM tree
i used this code to create a new document:
static public Document createDocument(String fileName) throws ParserConfigurationException//,IOException,SAXException
          try {
               DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
               factory.setIgnoringComments(true);
               factory.setIgnoringElementContentWhitespace(true);
               factory.setValidating(true);
               DocumentBuilder builder =factory.newDocumentBuilder();
               return builder.newDocument();
//          handle exception creating DocumentBuilder
          catch ( ParserConfigurationException parserError ) {
                    throw new ParserConfigurationException();
          }then i used this code to transform the DOM :
public void exportDocument(Document document) {
          try {
               Source xmlSource = new DOMSource( document );
               Result result = new StreamResult( System.out );
               TransformerFactory transformerFactory =
                    TransformerFactory.newInstance();
               Transformer transformer =transformerFactory.newTransformer();
               transformer.setOutputProperty( "indent", "yes" );
               transformer.transform( xmlSource, result );
       //then catching the exceptions
But the file was not created and i didn't find where can i specify the DTD that the XML file should use and where can i enter the name of the XML file itself
Another questoin can i write a DTD file dynamically during the execution of the program??

Generate an XML file from a DOM tree

Hi,
I'm trying to generate an XML file from a DOM tree that I obtained from another XML file with the Xerces library. I used the following operation :
public static void writeXmlFile(Document doc, String filename) {
try {
Source source = new DOMSource(doc);
File file = new File(filename);
Result result = new StreamResult(file);
Transformer xformer = TransformerFactory.newInstance().newTransformer();
xformer.transform(source, result);
} catch (TransformerConfigurationException e) {
System.err.println(e);
System.exit(1);
} catch (TransformerException e) {
System.err.println(e);
System.exit(1);
But I have this Windows/Linux problem. When I execute this on Windows, everything is correct. But if I try on Linux (every distribution does the same thing), I obtain an XML file where everything is written on just ONE LINE : there is neither identation nor carriage return at the end of a line ... And that is pretty annoying 'cause I need to SEE what I generate ...
Thanks for your answer,
Blueberryfin.

Actually I would think that no indents and no new-lines would be more correct, but maybe it's an option for parsers to do it either way if you don't specify it. If you want to specify it, look at this post from last month:
http://forum.java.sun.com/thread.jsp?forum=34&thread=383400

XML : Transform DOM Tree to XML String in an applet since the JRE 1.4.2_05

Hello,
I build a DOM tree in my applet.
Then I transform it to XML String.
But since the JRE 1.4.2_05 it doesn't work.
These lines failed because these variables became final:
org.apache.xalan.serialize.CharInfo.XML_ENTITIES_RESOURCE = getClass().getResource("XMLEntities.res").toString();
org.apache.xalan.processor.TransformerFactoryImpl.XSLT_PROPERTIES = getClass().getResource("XSLTInfo.properties").toString();The rest of the code :
DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = domFactory.newDocumentBuilder();
Document domXML = builder.newDocument();
// I build my DOM Tree
StringWriter xmlResult = new StringWriter();
Source source = new DOMSource(domXML);
Result result = new StreamResult(xmlResult);
Transformer xformer = TransformerFactory.newInstance().newTransformer();
xformer.setOutputProperty(javax.xml.transform.OutputKeys.INDENT,"yes");
xformer.transform(source,result);Is there any other way to get an XML String from a DOM tree in an applet ?
I'm so disappointed to note this big problem.

Does anyone have an idea why I get this error message when try to use transform in an applet?
Thanks...

How to convert DOM Tree in XML File

Hi there,
I am successful to build a DOM tree in memory where i am adding elements. Now after all this i want to make a XML file of that DOM representation. Now, i am confused with my code that how to transfer DOM structure to xml file ? A small code is attached herewith ?
doc = db.newDocument();
               doc.normalizeDocument();
               doc.setXmlVersion("1.0");
               doc.createComment("Created By: Sachin Kulkarni");

Is it any problem with the implementation ? How to use fileoutputstream with this ?

I have done like this:
DocumentBuilderFactory docBuildFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = docBuildFactory.newDocumentBuilder();
Document doc = builder.newDocument();
Element root = (Element)doc.createElement("Root");
doc.appendChild(root);
Element address = (Element)doc.createElement("Address");
address.appendChild((Element)doc.createElement("Street"));
address.appendChild((Element)doc.createElement("PostCode"));
address.appendChild((Element)doc.createElement("Town"));
Element country = (Element)doc.createElement("Country");
country.setAttribute("type","EU");
Text cname = doc.createTextNode("Spain");
country.appendChild(cname);
address.appendChild(country);
root.appendChild(address);
TransformerFactory tranFactory = TransformerFactory.newInstance();
Transformer aTransformer = tranFactory.newTransformer();
aTransformer.setOutputProperty(OutputKeys.INDENT, "yes");
Source src = new DOMSource(doc);
Result dest = new StreamResult(new FileOutputStream(new File("test.xml")));
aTransformer.transform(src, dest);

How to create a new DOM tree with nodes from another DOM tree?

Hello,
I would like to create a DOM tree by using nodes from an existing DOM. How can I do that? I tried with appendChild and it gaves me as error: "WRONG_DOCUMENT_ERR".
Thx!

The xml that should be parsed is something like that:

Serialization of DOM Tree+calling POST method in servlet

Hi all,
I am trying to serialize a DOM tree and send it from an applet to a servlet..I am having difficulty in calling the post method of the servlet..can anyone please tell me how the POST method in the servlet is called from the applet...I am using the code as seen on the forum for calling the POST method as below:
URL url = new URL("http://localhost:8080/3awebapp/updateservlet");
HttpURLConnection con = (HttpURLConnection)url.openConnection();
con.setUseCaches(false);
con.setRequestProperty("Content-Type","application/octet-stream");
System.out.println("Connected");
con.setDoOutput(true);
con.setRequestMethod("POST");
System.out.println("do output called");
con.setDoInput(true);
System.out.println("do Input called");
ObjectOutputStream objout = new ObjectOutputStream(con.getOutputStream());
yet the post method in the servlet does not seem to be called....
another problem I had was trying to serialize a DOM document and send it to the servlet. I am using the following code to write the DOM document on an output stream..would this work:
OutputFormat format = new OutputFormat(document);
XMLSerializer serializer = new XMLSerializer( objout, format );
System.out.println("XML Serializer Started");
DOMSerializer newSerializer=serializer.asDOMSerializer();
newSerializer.serialize( document );
objout.flush();
objout.close();
...since the doPost method of the servlet is not being called I do not whether the above code would be sent to the servlet..
Any advice on the above two matters would be highly appreciated..

perhaps my piece of code may help You - relevant parts marked //<--,
but I have a problem when reading my object - which is a serialized DomTree :
Variant 1 : sending XML-data as string will arrive as should be, but parser says org.xml.sax.SAXParseException (missing root-element)
Variant 2 : readObject says java.io.OptionalDataException, but the DomTree will be parsed and displayed
-- snipp --
import java.io.InputStream;
import org.w3c.dom.Document;
import java.net.*;
import com.oreilly.servlet.HttpMessage; //<--
import java.util.*;
import java.io.ObjectInputStream;
myApplet :
try {
     URL url = new URL(getCodeBase(),"../../xml/FetchDocument");
     HttpMessage msg = new HttpMessage(url);
     Properties props = new Properties();
     props.put("InputFeldName","FeldWert");
     InputStream in = msg.sendGetMessage(props);
//<-- alt : sendPostMessage
     ObjectInputStream result = new ObjectInputStream(in);
     try {
     Object obj = result.readObject();
myServlet :
public void doGet(HttpServletRequest req,HttpServletResponse res)
     throws ServletException, IOException {
TreeCreator currentTree = new TreeCreator();
ObjectOutputStream out = new ObjectOutputStream(res.getOutputStream());
-- variant 1 :
out.writeObject(currentTree.skillOutputString());
out.flush();
out.close();
-- variant 2 :
OutputFormat( TreeCreator.cdi ); //Serialize DOM
OutputFormat format = new OutputFormat( currentTree.getCDI() ); format.setEncoding("ISO-8859-1");
XMLSerializer serial = new XMLSerializer( out, format );
serial.asDOMSerializer(); // As a DOM Serializer
serial.serialize( currentTree.getCDI().getDocumentElement() );
serial.endDocument();
out.flush();
out.close();

Writing Dom tree from JAXP

Once I build a DOM tree, how can I write the xml to a string or a file using
the JAXP API. Given any particular Parser implementation, I have been able
to find methods that allow me to write the xml. However, from the java api
(JAXP), there doesn't seem to be a mechanism for doing this. Please
advise...
regards,
todd

Hi Todd,
You can't write XML out using JAXP 1.0 -- that feature is not included in
the API.
But you can use the XML serialization package that is included in the
built-in parser and the bundled Apache Xerces parser. Check out the
weblogic.apache.xml.serialize, org.apache.xml.serialize packages. The
javadocs are at
http://www.weblogic.com/docs60/xerces/org/apache/xml/serialize/package-summa
ry.html
Cheers,
-Todd

How i can store a DOM Tree to XML file

I want to insert a xml documet into another another xml document and then store it.
for this i have parsed a xml document using com.sun.xml.parser and got its domtree in document doc1 by builder.getDocument(). After that i parsed another xml document and got it's domtree in document doc2 by builder.getDocument().
now i created a Document type doc . I create dom tree in doc that contains all the nodes of doc1 and insert the doc2 at a position . If i m printing this doc i got the required document. Now i want to store this doc into a xml file. so i paas thid doc and filename in which i want to store it into a function
public static void writeXmlToFile(String filename, Document document)
try
               // Prepare the DOM document for writing
     Source source = new DOMSource(document);
     // Prepare the output file
     File file = new File(filename);
     Result result = new StreamResult(file);
// Write the DOM document to the file
     // Get Transformer
     Transformer xformer = TransformerFactory.newInstance().newTransformer();
          // Write to a file
     xformer.transform(source, result);
catch (TransformerConfigurationException e)
     System.out.println("TransformerConfigurationException: " + e);
catch (TransformerException e)
     System.out.println("TransformerException: " + e);
but i m getting following error
Exception in thread "main" java.lang.AbstractMethodError: com.sun.xml.tree.ElementNode.getNamespacesURI()Ljava/lang/String;

thanks for the reply
i m able to do my job using
import javax.xml.parsers.*;
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder1 = factory.newDocumentBuilder();
     doc = builder1.parse(uri);
when i want to covert this doc into an xml file by passing this doc in the function below then it is ok..
public static void writeXmlToFile(String filename, Document document)
try
// Prepare the DOM document for writing
Source source = new DOMSource(document);
// Prepare the output file
File file = new File(filename);
Result result = new StreamResult(file);
// Write the DOM document to the file
// Get Transformer
Transformer xformer = TransformerFactory.newInstance().newTransformer();
// Write to a file
xformer.transform(source, result);
catch (TransformerConfigurationException e)
System.out.println("TransformerConfigurationException: " + e);
catch (TransformerException e)
System.out.println("TransformerException: " + e);
but i want to use com.sun.xml.parser like
import com.sun.xml.parser.*;
import com.sun.xml.tree.XmlDocumentBuilder;
XmlDocumentBuilder builder = new XmlDocumentBuilder();
Parser parser = new com.sun.xml.parser.Parser();
parser.setDocumentHandler(builder);
builder.setParser(parser);
builder.setDisableNamespaces(false);
parser.parse(uri);
doc = builder.getDocument();
when i m trying to store this doc into an xml file by passing this doc into funtion writeXmlToFile( filename, doc) then the errors occur (that i hav told in the first post)
plz help..

XML - DOM tree - XML

I'm building an application that takes an xml file, turns it into a DOM tree, then the user selects different options from a database to manipulate the internal information gathered by the original XML file, the program is a process and at the end of the process the original XML file has been updated with new information, i need help with finding some code to take the DOM tree information displayed to the user and save back out as a new XML file. any help would be greatly appreciated.

You can use JDOM, Xerces XMLSerializer, or J2SE's Transformer. The first 2 are pretty simple. The 3rd isn't too hard. An example can be found in code sample 3 on http://java.sun.com/developer/technicalArticles/xml/JavaTechandXML_part3/.

Using XSU to process multiple record sets

Have a design question about XML, Java and Oracle's XSU. This is a common task when importing external data that should be of general interest.
I have an incoming XML document with multiple records with a known DTD. Before the records can be inserted into the database, part of
the record must be used to do a lookup for a foreign key. The resulting foreign key is then combined with the other part of the
record to create a valid input record for the database.
My question is what's the most efficient way to do this? I assume the general approach must go something like:
begin
while (records in xml doc)
1. parse the incoming XML to extract the next record
2. if the lookup data change, do a lookup for this record using XSL
3. combine the resulting foreign key with the data to create
an insert query
4. add the insert query as a document fragment to a second XML document.
use XSU to insert the second XML doc with multiple records.
end
I've figured out how to do most of this, except for step 1 above: is there an easy way to extract the next record from an XML doc if I know the row nodes and the DTD? Or do I just have to traverse all the XML nodes until I hit my next row tag?
Appreciate any suggestions; this is a handy discussion list!

Yes, typical behavior is that when you have multiple outputs it will create a one row IllumDoc to wrap them all together with OuputParameter=* (and the xml will be ignored unless it is the only output property or you've requested it by name).
How about just using "/Lighthammer/Illuminator?QueryTemplate=xxxx/yyyy&Content-Type=text/xml" or "/Lighthammer/Runner?Transaction=xxxx/yyyy&OutputParameter=OutputXML" which will both return your multi-rowset output?
I may be mistaken, but I believe the XacuteResponse was simplified to not include the Rowsets outer node because certain systems had problems digesting the layers, in fact you don't get the <Columns/> section either in the single Rowset.
Rick - any feedback to this SOAP simplification from Xacute?
