Pseudo code for DOM parsing a local XMl file

HI all,
1) Can any body please provide me the JAVA pseudo code for parsing xml document from local mcahine and create another xml document in another location in loca machine with small transofrmations ? (JAVA mapping using DOM parsing tehnique using an xml file in loca machine using NWDS).
2) Provide me with the links that can help me out to work with

Thanks,

What's the code for applying CSS to an XML file, in a dynamic text feild

Hi all,
Very simply put, just like in the title.
If you have a CSS ready, an XML file that already appears
inside a dynamic text field, what AS2 code would you use to connect
the CSS so it applies to the XML file which is now unstyled?
thanks!!!

...sorry for thaking a while to get back to you. I pluged the
code you provided and the exported flash does not deplay the text.
instead it says "undefined" which to me means something in the xml
files is work, which is strage since I tested the xml file in a
browser and it works find. so i am providing both the AS code
(below) and the xml and css file (attached). my hope is that you
can direct me to what the problem is.
THANK YOU AGAING FOR ALL YOU HELP!!!

Jersey WebResource output as input for DOM parsing

I'm working with REST web services, and introducing myself to Jersey and DOM. The code below retrieves an XML response from Flickr's REST api (I know there are wrapper libraries for this API, but I want to learn the nuts and bolts of it).
Client client = Client.create();
WebResource webResource = client.resource("http://api.flickr.com/services/rest/");
MultivaluedMapImpl queryParams = new MultivaluedMapImpl();
queryParams.add("api_key", "<my key>");
queryParams.add("method", "flickr.photos.search");
queryParams.add("text", "dog");
queryParams.add("per_page", "10");
queryParams.add("page", "1");
String s = webResource.queryParams(queryParams).get(String.class);
's' in this case is the XML response as a String. What I want though, is to have the XML as an object of a class that can be passed as a parameter to the parse() method of org.w3c.dom.Document, as in the following:
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document dom = db.parse(s);
The parse() method has five overloads:
parse(File f);
parse(InputSource is);
parse(InputStream is);
parse(String uri);
parse(InputStream, String systemId);
The one that takes a String is actually asking for a URI to the XML file. So what I want is to use the get() method of WebResource (above) to obtain the XML in a form that can be passed to one of the parse() methods. Does anybody know an efficient method of doing this? I don't really want to create a File just to pass it to the DocumentBuilder...

Disclaimer : I know little of XML parsing APIs, I just browsed the API javadoc for this answer.
The parse() method has five overloads:
The one that takes a String is actually asking for a URI to the XML file.Good catch - I would have fallen in the trap too :o)
parse(File f);
parse(InputSource is);
parse(InputStream is);
parse(String uri);
parse(InputStream, String systemId);See the InputSource version: an InputSource instance can be built out of a StringReader.
Something along the lines of:
Document dom = db.parse(new InputSource(new StringReader(s)));J.
P.S.: please use tags when posting code.

Should I go for DOM-parser for my THIS application?

Hello Forum ,
I need suggestions from all of you. I tell you about xml-use in my
application in brief :
we have a huge xml-file which represents properties and settings in
some business tool and getting reflected in Swing-based-UI.
So next time when user starts the application , we parse the whole xml-file
(using SAX-api based parser) and create one object (I have one class called IDOM ) which represents the whole xml-file AND then we operate on this object . Later when user chooses
the option "SAVE" , we take this object and generate (write) xml-file again .
FLAW : after parsing the existing xml-file , even if user changes one attribute-value in that huge
xml-file , we generate whole-xml-file all of again and save it .
Shall DOM be the better option for this aplication ?
Bcoz what i feel that why we avoid
DOM for huge xml file is that it creates in-memory representation of whole xml-file causing
memory-usage problem , performance and all . BUT what we are doing is nothing but the same
thing by creating object of our IDOM-class . Moreover , i suspect that our object must be consuming
more memory than that of DOM-object . Why bcoz , for example , we are using Hashtable and
Java automatically assigns a fixed amount of memory to it , even if data inside doesnt need that much...and for that we are not doing any optimization .
sorry for long message .Could you please find some time to give me your valuable suggestion?
thanx in advance for ur time n help,
Rajesh

thanx gseel..
actually we have two side of the application :
One : for creating Tool ie methodology for the end user . This is single-user task
BUT we create IDOM and may hold it for 2-3 hrs also. This is the side where
we manipulate the large-xml , only adding-delete-update attributes , elements
depending on what properties user set in Swing-based UI . Note that we dont
do any delete/add as such BUt whatever user update it gets reflected in IDOM
object and while Save , we take the IDOM-object and write xml-file once again.
TWO : This is the user side , where Tool created in first side is used . This is meant for
multiple user ( 200 to 300) .This side we dont manipulated XML , just parse the
XML , create IDOM object and use the data for business purpose .But ofcourse
each client will be having one IDOM object.
regds,
Raj

Unmarshalling a DOM node to an XML file with JAXB

I'm trying to unmarshall a DOM node to an XML file using JAXB. However I keep receiving a NullPointerException. This only seems to occur when I create the DOM Node from scratch. The stack trace looks like the following:

Flex Photoshop Panel won't read local XML file

I've created a panel for Photoshop which reads an XML file to populate some controls. When run from Flash Builder 4 through the web browser it works just fine, but when run from within Photoshop the XML file is not being read. Uploading the XML file to a web site and referencing it via URL in the panel works sucessfully in both the web browser and from within Photoshop, suggesting some type of security issue.
The Panel Developer's Guide FAQ talks about giving the Adobe Flash Player trust permissions by creating .cfg files that reference the folder the panel is running from.
I have created these .cfg files and placed them in both:
/Library/Application Support/Macromedia/FlashPlayerTrust
and also in:
USER/Library/Preferences/Macromedia/Flash Player/#Security/FlashPlayerTrust
but the problem remains.
Environment:
Mac OSX 10.6
Photoshop CS5
Flex Builder 4
Flex SDK 3.5
Any help/suggestions appreciated.

I had the same issue but I got it to work. I figure I update this thread in case somebody is trying to do the same. I didn't need to use javascript in order to load the XML. Just create the XML object:
<mx:XML id="myXML" source="data.xml" format="e4x"/>
Remeber to use e4x. The in the AS3 code I bound it to a var:
private var _XML :XML;
_XML = myXML;
then....
private var _itemsXMLList :XMLList;
_itemsXMLList = _XML.node;
Don't forget to add "-use-network=false" to the properties > Flex compiler > additional compiler arguments.
Hope that helps.

Non-blocking parsing of multiple xml files

Hi there,
I'm trying to parse multiple huge XML files concurrently for a query system over multiple xml streaming systems.
For each huge xml file, I read them into the memory gradually (the new data would cover the old data in the buffer if the buffer is full). Two questions here:
1. Do I have to set up a socket and write the buffered data to the socket in order to simuate that the parser can parse infinitely? It sounds not good to use socket across two threads just for the "infinite" nature.
2. I want to simulate concurrently parsing multiple streams. A straightforward way is to have each parser sit in a thread. Is there any otherway that I can put all parsers in one thread and alternately call them? This requires that each individual parser could parse whatever they have seen so far rather and resume when they are called again.
I'm curiously awaiting for your answers.
thanks a lot,
hong

just taking a guess: create your own reader by extending java.io.Reader ; and let this reader taking care of fetching the data that the parser will use.

Working with local xml file

Hi, I would like to work with a local xml file, but I don't want to point to a strict location as I would like my application to run on a few different machines.
Is there a special place within Netbeans project structure that I can place such files?
Say if I try and load a file "somefile.xml" - where is it going to look first?
I have a <default package> with my settings.xml in there. How can I reference this within my app?

There you would place such a file in the <tt>main/resources</tt> folder
Say if I try and load a file "somefile.xml" - where is it going to look first?I'ts going to look for it where you tell your program to.
When created as <tt>new File("somefile.xml")</tt> it will bee searched in the <i>currend working directory</i>. The problem with that is that it is unreliable what this will be at runtime (once your Program left your IDE...).
You should better get it via <tt>getClass().getResource("somefile.xml")</tt> But in this case the file must be present in the classpath in the same package as the Class aquireing it. Adding a <tt>'/'</tt> in front of the file name expects it in the root directory of a classpath entry.
I have a <default package> with my settings.xml in there. How can I reference this within my app?<tt>getClass().getResource("/settings.xml")</tt>
But in case you include it into the delivery jar file it will not be writable. Also you cannot expect the installation folder of your App to be writable. On startup of your program you should copy your (default) settings to a writable place like <tt>new File(System.getProperty("user.home2),".myApp/settings.xml");</tt> and modify it there.

How to bind to local xml file?

I have a local XML file referenced in my Declarations tag:
<fx:Declarations>
<fx:XML id="myXMLdata" source="assets/names.xml" />
</fx:Declarations>
I previously had a proof of concept version working with the XML defined in my MXML with a bindable tag:
[Bindable]
public var names : XML= <root>
etc., etc.
I need to place the xml in a separate local file so that changes to the file will persist.
How do I do this and bind to it?
thanks
MCE

http://www.adobe.com/devnet/air/flex/quickstart/xml_prefs.html - This should help you, i guess.
In short,
private function saveXML():void
personXML.firstName = fName_txti.text;
personXML.lastName = lName_txti.text;
var newXMLStr:String = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" + personXML.toXMLString();
var fs:FileStream = new FileStream();
fs.open(file, FileMode.WRITE);
fs.writeUTFBytes(newXMLStr);
fs.close();
This function can be the eventHandler function for, say an XML change event etc.
Hope this helps,

Is there a way to Point the Exact Location for an Error In an XML File?

Dear Members,
I am validating an XML File with an XML Schema. The XML Schema is in the Database.
I am using presently isschemavalid to check for the validity of the XML File.
But this is not showing where the error is there in the XML File.
Is there any way where I can check this one...(Validation should happend only in the Database side)
Regards
Madhu K

Read about advantages of [url http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14259/xdb03usg.htm#sthref315]schemaValidate method over isSchemaValid.

Write data to local xml file

Does anyone know if there is a way to write data to a local xml file using the Connection refresh Button??

Hi there Glenn,
That's tricky...
Are you using SP1? You need to have at least SP1.
The XLFs were generated with an internal build newer than SP1, but they should still work in earlier builds.
If you changed the HTML file, that might be the cause. The SWF references in the HTML file must be exact.
Also, the range names must match as defined in the XLF/SWF. The bolded lines following should match. It's easiest if they all use the SWF name.

JAXB parsing an incomplete xml file

hi folks,
i am trying to parse a incomplete xml file (e.g some attribute and child elements are missing) in order to complete it via jaxb. however, parsing throws a SAXParseException (premature end of file), which interally is marked as unrecoverable, and a unmarshaller isn't capable of returning a result. not even the objects created so far.
so my question is if there a way of getting the (incomplete) object tree no matter if the parsing was successfully or not. (i am aware of the fact, that this object tree might be invalid)
cheer, johannes

Thanks, works like a charm :)
Another question.
I have an index.jsp page with an HTML form (a simple "search" form, made of a text area and a submit button). Now, what I want to do is passing the parameter to two distinct servlets, each one dealing with a web service (one with ebay, the other one with last.fm).
Unfortunately, in the action tag of the form only one value can be specified.
Any suggestions?

Using a local XML file for parsing - iPhone

Good afternoon everyone. I am trying to create an application for the iPhone that will use an XML file for it's data source. I have been attempting to convert the SeismicXML application from the dev center to use a locally stored file, but to no avail. I have it building and running fine, but no data is appearing. Is there anyone that can give me an example of parsing with a locally stored file? Thanks!

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"myFile" ofType:@"xml"];
NSData *myData = [NSData dataWithContentsOfFile:filePath];
