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.

How to call a html file in a java file

how to call a html file inside a java file ?

Hopeless. Are you by any chance a rare gas? You seem completely inert. LOL You totally pwned him there :rolls eyes:
well, no, I think he's looking for something to this degree:
in HTML, there is a mailto: command that makes the system default handled way to email emails open up. He's looking for a command thats very nice and opens a html file in the system default browser.
So, Dick, Runtime.exec would work execpt that he needs a way to find the default system browser to call exec on, AND he has to know how to pass html file locations to the executable via command line arguments
He just didnt try to phrase it at all :P

Parse local HTML files

Hi,
I want to parse local HTML files.
Is there another way than using the Internet Explorer($ie = new-object -com "InternetExplorer.Application";) (without relaying on external packages)?
At the moment I do something like that:
$ie = new-object -com "InternetExplorer.Application";
Start-Sleep -Seconds 1
$ie.Navigate($srcFile)
Start-Sleep -Seconds 1
$ParsedHtml = $ie.Document
foreach($child in $ParsedHtml.body.getElementsByTagName('table'))
I still want to have the methods like 'getElementById()' or 'getElementByTagName()'.
With my current approache, the performance is not realy good and it seems that the iexplorer.exe process is not terminating at the end of the script.
Also it seems to have sideeffects with running internet explorer instances (from GUI) - not working to start IE in powershell sometimes.
Last time I also have a hanging script, not continuing till i manually terminate the iexplorer.exe process.
The error was:
Exception calling "Navigate" with "1" argument(s): "The remote procedure call f
ailed. (Exception from HRESULT: 0x800706BE)"
At D:\Scripts\Run.ps1:529 char:14
+ $ie.Navigate <<<< ($src)
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : ComMethodTargetInvocation
so I would prefere a method parsing HTML without IE.

Hi John Mano,
Please also try to Parse local HTML files with
System.Xml.Linq, the script may be helpful for you:
Using PowerShell to parse local HTML files
I hope this helps.
XML?
I thought HTML is not compatible with xml.
And as I don't know LINQ good ...
Ok, I'll give it a try. later.
I can't answer the question about other ways to parse HTML, but to close your IE session you should do the following:
$ie.Quit() # this terminates the IE process
$ie = $null # this frees the COM object memory
Thanks for that.
I now use that, but seems to be still some IEs open ...
Maybe a path missing where i dont do it.
But finally I still get this error. And it is blocking the whole script ...
Exception calling "Navigate" with "1" argument(s): "The remote procedure call f
ailed. (Exception from HRESULT: 0x800706BE)"
At E:\DailyBuild\Scripts\PublishTestResults.ps1:533 char:15
+ $ie.Navigate <<<< ($srcFile)
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : ComMethodTargetInvocation

hi srikkant,
ur html code is inside the source code..? are you working on applets..? if ur html file can be read as a file and the file stream can converted to a string and put into a Jeditor pane using the setText() method. for editing HTML text a editor called javax.swing.text.html.HTMLEditorKit can be used.
Refer to JAVA API for further clarifiactions and examples.

How quickly parse big XML file (60 MB) ???

How quickly parse big XML file (60 MB) ???

I assume you mean load it into XML DB ?. Fundamentally your document is about the upper limit for 9.2.x. I would strongly recommend trying to break it up into a set of smaller documents using a SAX parser before trying to load it into XML DB. In 10g it should be possible to load much bigger documents than this.

Shehzad <[email protected]> wrote:
1. You can create a link to that directory
2. In order to get rid of port number, either boot weblogic at default
port 80, or use Apache or Iplanet webserver, and use Weblogic plugin.
That way all the traffic comming in from http will comein at port 80
to the webserver, and would then be forwarded to Weblogic at whatever
port it is booted.

How to use Swing html to parse a html file..

I am currently working on a project in java.i need to read a Html file, extract the table tag along with its contents if it has a button embedded in it and replace it with another code..
i tried it with Reg Ex in java but in vain.. Any help is great... I need an idea of how to use Html parser for this prob.. any examples will be fine..

Run the program from command line, this way you will see the errors, if any.
example.: java -jar theJarfile.jar
I was successful in creating a comm application. I placed the win32com.dll in the same directory of my application jar file and all worked.
I also extracted the comm.jar , and jar'd my app with the extracted comm files to make one jar.
I also had a fileWriter() to get the clients jre path and my app would write the javax.properties file to the correct place.
It took me severel weeks and late nights to accomplish this, but it was all necessary to be able to install only my app, and not a bunch of api's that were needed.

Preventing CFMX7 to parse all .html files

hi,
I have coldfusion MX 7 installed and integrated with IIS6 on
windows2003 server. To parse .html files through coldfusion, i have
added the following lines to
(C:\CFusionMX7\wwwroot\WEB-INF\web.xml) web.xml files
<servlet-mapping id="macromedia_mapping_14">
<servlet-name>CfmServlet</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
<servlet-mapping id="macromedia_mapping_15">
<servlet-name>CfmServlet</servlet-name>
<url-pattern>*.html/*</url-pattern>
</servlet-mapping>
i have vhost site in IIS6 named something.abc.com , to make
sure that only .html file for something.abc.com site wiill be parse
through coldfusion MX 7, i have added .html extension mapping to
C:\CFusionMX7\runtime\lib\wsconfig\jrun_iis6.dll.
after restarting both coldfusion and iis6, I found that not
only for vhost site(something.abc.com) but also for others sites "
.html " files are parsing trhough coldfusion server, which is not
my requirements. My requirements is .html file will be parse only
for those vhost site that has .html extension mapping, other
vhost's .html file should be served by IIS6.
Any idea how to do this??
Please Help..
Mamun

I'm also interested in this.
We have a specific site that we would like to have ColdFusion
process the .html files, but when setting up IIS and the web.xml
file it seems to setup coldfusion to process all sites html files
instead of just the one site.
Is there a way to set the URL-PATTERN in the web.xml to just
match a specific URL? Or does it only match directories and files
under the URL string?
Any guidance is appreciated.
Thanks

How to open a html file from hard disk

Hello everyone,
i want to display a html file by using java applet.
This is my current coding:
package mkbe.pg;
import java.net.*;
import java.applet.*;
public class HtmlReader extends Applet
URL userUrl;
public void start()
try{
userUrl = new URL(getDocumentBase(),"FILE:///c://2007/index.htm");
}catch(MalformedURLException error){
System.out.println("Error");
getAppletContext().showDocument(userUrl,"_blank");
}the program have no error and warning and the applet did run by appletviewer but the html file did'nt open.
Is it there's mistake in my coding?
If there is please tell me how to repair it.
Thanks

For an applet to read from a client's harddrive it will need permission.
This can be done by putting the applet in a jar file and signing it,
or by using the poiclytool to change the java.policy file to give FilePermission.
