Parsing a XML file using bracket notation

Hi Gang-
I have been given the task to parse a .xml file.
The xml file contains element names that contain hyphens, so I've read that bracket notation is the only way to go. According to Ben Forta I have built the following code, but because of what I believe to be a simple syntax issue that I simply cannot put my finger on I can not get it to work:
1. <cffile action="read" file="/Applications/Coldfusion8/wwwroot/config/ModelGlue.xml" variable="xmldoc">
2. <cfset mydoc=XmlParse(xmldoc)>
3. <cfset newLen=#arraylen(mydoc.modelglue.xmlchildren[2].xmlChildren)#>
4. <cfoutput>
5.     <cfloop from="1" to="#newLen#" index="i">
6.         xmlObject["mydoc"]["modelglue"]["event-handlers"]["event-handler"][i].xmlAttributes["name "]<br>
7.     </cfloop>
8. </cfoutput>
When I run the code line 6 literally appears on screen the proper amount of times, according to the "to" value in my loop.
I tried putting pound signs around line 6 but it returns an error saying that "... xmlObject is undefined..."
Because of the hyphens it seems that I'm forced to use the bracket notation (I'm OK with that) but does anyone know how to render line 6 to obtain the value?
Thanks in advance,
Rich

LOL
This is what you get for working 12 hours straight....
I changed:
xmlObject["mydoc"]["modelglue"]["event-handlers"]["event-handler"][i].xmlAttrib utes["name"]<br>
to:
#mydoc["modelglue"]["event-handlers"]["event-handler"][i].xmlAttrib utes["name"]#<br>
xmlObject is the name of my xml object in memory, and then you reference from the root of the xml doc down the chain.
Sorry for the inconvenience,
Rich

Parsing a XML file using Jdom-Problem.

Hi all,
I am reposting it as I was told to format the code and send it again.
I am trying to parse a xml file using a jdom java code.This code works fine if I remove xmlns attribute in the root element. (I get the expected result) .If the "xmlns" attribute is put in the xml as it should be then the parsing and retrieving returns null. Please tell me how to fix this issue.

Parsing an xml file using xerces DOM parser

Hi
I want to parse a simple xml file using DOM parser.
The file is
<Item>
     <SubItem>
          <title>SubItem0</title>
          <attr1>0</attr1>
          <attr2>0</attr2>

I just want to parse this file and want to store the values in desired datastructures,
I am trying using DOM parser, since it gives a tree structure, which is ok in this case.
public void init()
          InputReader ir     =new InputReader("Habsys");
          Document      doc     =ir.read("Habitat");
          System.out.println(doc);
          traverse(doc);
private void traverse(Document idoc)
          NodeList lchildren=idoc.getElementsByTagName("SubItem");
          for(int i=0;i<lchildren.getLength();i++)
               String lgstr=lchildren.item(i).getNodeName();
               if(lgstr.equals("SubItem"))
                    traverse(lchildren.item(i));
private void traverse (Node node) {
int type = node.getNodeType();
if (type == Node.ELEMENT_NODE)
System.out.println ("Name :"+node.getNodeName());
if(!node.hasChildNodes())
System.out.println ("Value :"+node.getNodeValue());
NodeList children = node.getChildNodes();
if (children != null) {
for (int i=0; i< children.getLength(); i++)
traverse (children.item(i));
But I am not getting required results, a lot of values I am getting as null
Could anybody tell me how to retrieve the data from the xml file, I simply want to read data and store it in data structures. For eg, for tag Subitem with title as ' SubItem1' has attr1 as '1', attr2 as'0' and attr3 as '0'.
Thanks

Normally if you have no idea about X, the first thing you should do is google "X tutorial". You will find plenty of them out there. And the advantage is, they are better written than whatever we spend two minutes throwing together here. Not to mention that it saves us the two minutes.
But if you have specific questions with your SAX parser when you get it going, then ask them here. Actually, ask them in the XML forum here, not this one.

Hi
Thanks a lot for your swipt reply.
I try this also But error is same.
<x:parse var="output" xml="${xml_data}" />
javax.servlet.ServletException: Unrecognized object supplied as 'xml' attribute to <parse>
at weblogic.servlet.jsp.PageContextImpl.handlePageException(PageContextImpl.java:409)
at jsp_servlet._portlets._news.__news._jspService(__news.java:
<%=xml_data%> returning me a output just as name of file and not content --- > test.xml
After putting isMultiple="false" i am getting output as ----> test.xml
resultId defination
The name of the script variable to store the value of the property in. If this is not specified, the value of the property will be printed in the JSP instead. The value of the property is returned as a collection by default, unless the isMultiple attribute is set to false.
I think this approch is simple if we can solve this. Is there ant other way same as using tag in jsp itself to retrieve required XML tags. Please reply.. Also i am using Jsp/Html Portlet and not Page Flow Portlet

How to parse the xml file using servlet

My scenario is like this:
<b>FILE-->XI-->J2EE Application</b>
XI sends the xml file to j2ee application. My servlet receives the file in HTTPRequest string.
How to parse that file using servlets.I should get the xml file as it is and should be displayed in the browser.
Can anyone please help me with code, its urgent.
Please help me!

Download this java code
http://java.sun.com/webservices/jaxp/dist/1.1/docs/tutorial/sax/work/Echo02.java
in your servlet code you can write
public void doPost(req,resp){
DefaultHandler handler = new Echo02();
handler.parse(req.getInputStream());
Offcourse you will need to modify the code of Echo02 class a bit to suit your requirement which would finally retrun you a string and you can then write it using
respose.getWriter().write(responseString);

How to parse a XML file

I am a new learner to XML & JAVA,I dont't know how to parse the XML file using JAXP,Who can tell me,Who can write an Example?
thx
Best Regards.

Using the SAXParser in JAXP the parsing of the XML file is event driven.
Instantiate the parser:
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser parser = factory.newSAXParser();
InputSource is = new InputSource(new FileReader(theXML));call the parse method:
parser.parse(is, this);The following events are fired as the parser works through the XML public void startElement(String namespaceURI, String localName, String qName, Attributes atts) throws org.xml.sax.SAXException
public void endElement(String namespaceURI, String localName, String qName) throws org.xml.sax.SAXException
characters(char[] ch, int start, int length)etc.
You write what you want within each of these sections to handle the structure of your data. Keep in mind SAX is useful only when you know the structure of your XML.

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.

How can i do this ?
Sachin Kulkarni

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.

How different Web Services can use a class which parses an XML file

I am using RAD6.1 for developing and deploying web services.As I am using 15 web Services which uses a common class which is used to parse an XML file.As this XML file should be parsed only once and should be used by all the web services.I have made this common class as Singleton but it works as singleton for only one webservice and for other web service again it is parsing the xml file.I want to parse this xml file only once and used by all the web services.In my case tis file is parsed 15 times for 15 web services, but it should be parse donly once and used by all 15 services.Please give me the solution.
Thanks and Regards
Sayeeduzzaman

Hello,
the 15 Webservices should have a static attribute which contains the xml:
private static String xml;
then initialise the xml like this:
if (xml == null)
xml = parseIt();
else
//do nothing, XML already initialised!
}

Cannot close an XML file used for parsing

Hi All,
I appears to have difficulty closing (possibly flushing it first) an XML file that was subsequently being parsed without success. The error generated is:
org.jdom.input.JDOMParseException: Error on line 23: The element type "form" must be terminated by the matching end-tag "</form>".
Below is the code snippets of readData() to retrieve (HTML) data from a website, save it to a file, then convert to XML format before returning the new filename:
public String readData() {
    try {
          URL url = new URL("http://www.abc.com");
          URLConnection connection = url.openConnection();
          InputStream isInHtml = url.openStream();   // throws an IOException
          disInHtml = new DataInputStream(new BufferedInputStream(isInHtml));
          System.out.flush();
          FileOutputStream fosOutHtml = null;
          fosOutHtml = new FileOutputStream("C:\\Temp\\ABC.html");
          int oneChar, count=0;
          while ((oneChar=disInHtml.read()) != -1)
              fosOutHtml.write(oneChar);
          isInHtml.close();
          disInHtml.close();
          fosOutHtml.flush();    // optional
          fosOutHtml.close();
    try {
          File fileInHtml = new File("C:\\Temp\\ABC.html");
          FileReader frInHtml = new FileReader(fileInHtml);
          BufferedReader brInHtml = new BufferedReader(frInHtml);
          String string = "";
          while (brInHtml.ready())
              string += brInHtml.readLine() + "\n";
          fwOutXml = new FileWriter("C:\\Temp\\ABC.xml");
          pwOutXml = new PrintWriter(fwOutXml);
          light_html2xml html2xml = new light_html2xml();
          pwOutXml.print(html2xml.Html2Xml(string));
          system.out.flush()     // optional
          fwOutXml.flush();      // optional
          fwOutXml.close();
          pwOutXml.flush();      // optional
          pwOutXml.close();
          return fileInHtml.getAbsolutePath();
// parseData reads the XML file using the name returned by readData()
public void parseData(String XMLFilename)
    try
        FileReader frInXml = new FileReader(FileName);
        BufferedReader brInXml = new BufferedReader(frInXml);
        SAXBuilder saxBuilder = new SAXBuilder("org.apache.xerces.parsers.SAXParser"); // JDOMParseException generated.
}These codes would worked when they were in a single method but I have since placed some structure around them using a number methods.
This issue has risen in th past where I have been able to close the XML file prior to reading them again. However, I don't have a solution for it this time round.
I am running JDK 1.6.0_10, Netbeans 6.1, JDOM 1.1 on Windows XP platform.
Any assistance would be appreciated.
Many thanks,
Jack

Hi Alain,
I have added the additional I/O statements in the finally clause as follows but the problem still persisted:
readData()
// reading data (html) from the webpage and save it in html format.
try {
catch { . }
finally {
       System.out.flush();
       isInHtml.close();
       disInHtml.close();
       fosOutHtml.flush();
       fosOutHtml.getFD().sync();
       fosOutHtml.close();
// convert the html webpage format to xml format
try {
catch { . }
finally {
       System.out.flush();
       fwOutXml.flush();
       fwOutXml.close();
       pwOutXml.flush();
       pwOutXml.close();
Below is a short listing of the new XML file:
<?xml version="1.0" encoding="iso-8859-1" ?>
- <html>
- <head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<meta name="keywords" content="California, cities, towns, villages, list, zipcodes, postal codes, united states, ca" />
<meta name="description" content="Cities, towns and suburbs in California, United States (CA) starting with A" />
<title>Cities and Towns in California starting with A ABC Company</title>
<link rel="stylesheet" href="http://www.abc.com/style.css" type="text/css" media="screen" />
</head>
- <body>
<a name="top" />
- <div id="container">
- <div id="header">
<div id="postmark" />
- <a href="http://www.abc.com/" class="imglink">
<img id="logoimg" src="http://www.abc.com/images/zipcodes.gif" width="192" height="33" alt="Zipcodes America Logo" />
</a>
<hr />
</div>
- <div id="nav">
- <ul>
- <li>
<a href="http://www.abc.com/" title="Home Page">Home</a>
</li>
- <li>
<strong>Search</strong>
(zipcode or suburb)
- <div class="hide">
<form method="post" action="http://www.abc.com/search" />        // line 23
</div>
<input type="text" name="q" class="searchbox" alt="Search query" />
<br />
<input type="submit" value="find!" class="searchbutton" alt="Perform search" />
<div class="hide" />
</li>
What I find it interesting is that it is possible to parse the above XML file with the same parseData() from another class without any problem. As a result, I have come to the following conclusion so far:
( i ) There is some file locking that is prevent saxBuilder from parsing the XML file at the time.
( ii ) The light_html2xml does not appears to have correctly converted over the orginal Html to Xml but some how it has been picked up by the parser in the same class, but not by the same parser from another class.
( iii ) I would like to use another conversion tool such as Tagsoup in place of light_html2xml to determine where the cause of this issue is coming from. As a result, would you or anyone be able to assist me coming up with a few lines of conversion statements using Tagsoup since I am not familiar with using this tool?
( iv ) light_html2xml is good as it strip out all namespace, DTD, Entity Resolver, etc and only return what I need. JTidy does correct conversion but include namespace, DTD, Entity Resolver which makes parsing difficulty.
Many thanks again,
Jack

I had a similar error which when I searched, came up with this thread.
My issue was resolved after I discovered that my RTF template was not really RTF. It was sill in MS Word DOC format. This was discovered by reviewing two templates in NOTEPAD. The MS-DOC files have a lot of "special" characters in them. My RTF was not really RTF.
After doing a SAVE AS - RTF format, then the preview worked as expected.

Can someone help me with a problem of parsing an XML file?

Hello,
I'm having some problems parsing an xml file. I get a SAXNotSupportedException when setting a property value.
Here is the piece of code where I have the problem:
SAXParserFactory spf = SAXParserFactory.newInstance();
spf.setNamespaceAware(true);
SAXParser saxParser = spf.newSAXParser();
XMLReader xmlReader = saxParser.getXMLReader();
DefaultHandler defHandler = new DefaultHandler();
xmlReader.setProperty("http://xml.org/sax/properties/lexical-handler", defHandler);
and the log is:
Problem with the parser org.xml.sax.SAXNotSupportedException: PAR012 For propertyID "http://xml.org/sax/properties/lexical-handler", the value "org.xml.sax.helpers.DefaultHandler@4ff4f74a" cannot be cast to LexicalHandler.
http://xml.org/sax/properties/lexical-handler org.xml.sax.helpers.DefaultHandler@4ff4f74a LexicalHandler
I've been working on this problem but I can't find the error.
Does anyone have an idea of what to do to solve it?
Thanx in advance,
M@G

before deciding which XML technology to use, you should see if your application fit in the category below:
use SAX:
1. The XML file is rather large (30 or 40+ MB)
2. I don't need the xml document in memory. I will parse the document and store the data in my own object.
use DOM or JDOM
1. The XML file is relatively small (less than 30 MB) or I can increase the runtime memory for larger xml file.
2. I will need to walk up and down the xml document tree severals time.
3. My application is in Java and it's not going to be rewritten in C++, etc (use JDOM)
NOTE:
JDOM is rather easier to use (for Java developer), but it's not an www.org.com standardlized xml parser.
personally, i like JDOM for traversing the DOM.
