XML file (stream) parsing

Hi there!
My problem: I want to parse the "header" of a very large XML file (1MB approx.), but only the first elements (name, duration, datetime, file). Is there any simple way to just extract these first 4 Elements? Thank you so much in advance, help very apreciated!

You could write an input stream that wrapped the stream you're actually reading. As soon as the handler finds what it wants, it tells the wrapper to pretend that the stream has ended.Ewww... I was hoping for something like a cancel method somewhere. I remember looking once long ago and not finding it. Oh well...

Junk Characters in the output XML file after Parsing

Hi
I am using DOM parser to parse an XML file.
After parsing the input XML file, i am fetching some contents
from the same and also putting the same contents in the parsed output file which is also an XML file.
The problem here is that the after putting the contents to the output XML file from the input XML file,
some junk character appears at the end of each and every tag in the outputfile.
The junk character is some thing like this : " ampersand hash thirteen and a semicolon "
(*THE MESSAGE DID NOT ACCEPT THE SYMBOLS KINDLY TRANSLATE THE ABOVE WORDINGS*
INTO SYMBOLS)
This character gets appended at the end of each and every tag in the output file due to which the output file
is not recognised as an XML file.
Please let me know as to why is this character appearing and also please suggest some solution
for the same.
-Thanks in Advance.

How to indicate the Schema path for a XML file when parsing?

I have to validate a XML file. At the header line of this file, I need to specificate only the name of the schema but not the full path:
<DATAMODULES xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="Datamodules.xsd">
When validating, there is any way to specify to the parser the correct location of the XSD file?
I know I could copy the XSD file to the XML file directory or vice versa, but I cannot do that and I need a software solution.
Could someone help me?

An External Parsed Entity could be used to reference a schema.
In your DTD:
<!ENTITY datamodules SYSTEM "file:///c:/Datamodules/Datamodules.xsd">
Refer the external entity in xml document:
<datamodules>&datamodules;</datamodules>

Loading XML file for parsing

Folks,
I have placed one xxx.XML file under /WEB-INF/ of my application server and i have configured a servlet in web.xml file to execute during server startup like below
<servlet>
<servlet-name>MonitorInitServlet</servlet-name>
<servlet-class>com.xxx.xxx..services.MonitorInitServlet</servlet-class>
<init-param>
<param-name>configFile</param-name>
<param-value>/WEB-INF/portalMonitorConfig.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
And the above servlet loads portalMonitorConfig.xml file and i have below code
InputStream inputStream = xxx.class.getResourceAsStream("/WEB-INF/portalMonitorConfirg.xml");
private static Document parseXmlFile(InputStream xml) throws SAXException, IOException,
ParserConfigurationException
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setValidating(false);
return factory.newDocumentBuilder().parse(xml);
So when i do the above , i get
java.lang.IllegalArgumentException :InputStream cannot be null,
I know its sending a null InputStream, By the way i need to know what is the issue in the above code when i create InputStream object
InputStream inputStream = xxx.class.getResourceAsStream("/WEB-INF/portalMonitorConfig.xml");
Any help with the code is really appreciated

when serializing the DOM, use this: transformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM, scrReg.dtd");
Merry Chrasmas too ;-)

Loading xml file and parsing error in web start

Can you help me ? please :-(

I need to do a similar thing but in my case I don't know the structure of the xml file. I have 2 questions for this mapping. For an xml file like this:
<?xml version="1.0"?>

<author>Gambardella, Matthew</author>
<title>XML Developer's Guide</title>
<genre>Computer</genre>
<price>44.95</price>

<street>Heart St.</street>
<no>23/5</no>
</publisher_address>
<description>An in-depth look at creating applications
with XML.
</description>
</book>
</catalog>
If I'm right, I need to create a database named catalog and a table named book. But the problem comes out here: How can i store publisher_address? In a table or what? Other problem is, is there a difference between storing id attribute of the book and genre element of the book? I think they are just columns of the book table. But if I'm wrong what is the correct solution?

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!

Too big XML file to parse

I have this big xml file which is 13MB which I am trying to parse by Java. The problem is that I get the message
java.lang.OutOfMemoryError: Java heap spaceI am loading from xml file as following:
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
Document doc = docBuilder.parse (new File("xmlGeneSynonyms.xml")); //Here I get problem!!!Do you have any suggestion how I can work this out?
thanx

I agree with the poster who said SAX may be a better choice. 13 MB, though (probably) smaller than the memory space of your machine, is still going to take a while to parse & build the nodes in memory. Unless you are going to keep the parsed XML tree in a memory for a LONG time and do a LOT with it, SAX is likely a better choice.
With SAX, you just parse a little at a time until you find what you're looking for, then quit. This would be a better wa to go, for example, if want only few parts of the 13 MB document.
And how many 13 MB documents do you have? If more than just one or two, you're going to take a huge performance hit by trying to parse each one & stuff the whole thing into memory if you're only interested in a small part of it.

Want to accept XML file and parse it.

Hi Experts,
I want to develop an application in BSP where i have to accept XML file(File is given below) on internet,
and want to parse the data inside that file.
My doubts are
1.how to accept XML file
2.how to parse it and get the required fields from that XML,
here in case of my file i want these fields,
a.VERIFIED
b.OID
c.TVAL
d.REF
XML file :
<?xml version='1.0' encoding='UTF-8'?>

Please don't give generalize answer.
tell me all the steps in detail because i dont even know how i will accept that XML file on internet,
parsing will come later so please answer both the questions.
i dont know what is "HTTP Request".

How to compare after parsing xml file

Hi,
following code, parse the input.xml file, counts how many nodes are there and writes the node name and its value on screen.
1) i am having trouble writing only node name into another file instead of writing to screen.
2) after parsing, i like to compare each node name with another .xsd file for existence.
Please keep in mind that, input.xml is based on some other .xsd and after parsing i have comparing its tag with another .xsd
Need you help guys.

How can (parse) i use XML file with missing EndTag

hi,
i have an application which writes an "XML file".
another application should read that XML file, build an DOM and
access the nodes with xpath.
my problem. if the first application is not finished there are tags
missing. e.g. </xml>. but the seconds application cannot wait until the first application finishes it task.
if i now read the XML file the parser cannot load it because the end tags are missing.
my question:
how can i deactivate the check or how can i read the XML file and access it via XPath (my application is using at the moment XPath to access the nodes and i dont want to change that)
as parser i am using XERCES
alex

As far as I know, you can't do this - xml must be well formed (this is sort of a bedrock of xml). There may be some work around's, but I'm not aware of any - and they would most likely be hacks.

XML file input and parsing

In looking through the documentation for XML handling, I can
find no command for something as basic as how to read in a local
XML file for parsing and processing.
Can someone recommend a site with example code for
manipulating XML files?
I've done some of this before in Java and Perl. Does
ActionScript have similar facilities?

hsfrey,
I often put XML files onto the web server and then access
from Flex code. Something like this:
protected function load_settings_data():void
try
data_URL = "./data_settings.xml";
data_request = new URLRequest(settings_data_URL);
data_loader = new URLLoader(settings_data_request);
data_loader.addEventListener("complete",
settings_data_loaded);
data_loader.addEventListener("ioError",
settings_data_error);
} // try
catch (error:Error)
Alert.show("load_settings_data - error message " +
error.toString());
} // catch
} // load_settings_data
protected function settings_data_error(e:IOErrorEvent):void
Alert.show("ioError handled in settings_data_error: error "
+ e.text);
} // settings_data_error
protected function settings_data_loaded(event:Event):void
xml_to_use = XML(data_loader.data);
// do whatever you want with xml_to_use
} // settings_data_loaded
However, while you are developing on the local machine you
will probably want to have some dummy data in a variable:
[Bindable]
protected var data_internal:XML =
<root>
<stuff>abc</stuff>
</root>
and swap this data in in the catch part of the first
statement. Obviously the dummy data has to have the right structure
but you can usually get away with just a few entries rather than
the whole lot. Once you are happy, forget the local variable, put
back the error handling and just use the file on your web server
which can be updated whenever you want independently of the swf
application.
Hope that helps,
Richard

Writing XML files

Hello all
There's a vast amount of information on the java.sun.com site about parsing XML files:
* creating DOM trees in memory from an XML file
* setting up event handlers to be called when an XML file is parsed
* transforming XML files using XSL.
However, I can find very little information anywhere about writing XML files in the first place! I'm already aware of two ways to do this:
(1) create a DOM in memory and write this to a file. If the data is large, though, this isn't feasible.
(2) just output the XML elements directly to some file as text. This doesn't take account of the encoding, or special characters, and the document is not necessarily then syntactically valid.
Is there some API which I haven't yet come across that is designed specifically for writing XML data to files? If it's built in to Java 2, then goodness knows how I've missed it all this time; if it's third-party, I'd be grateful for any links.
Thanks for your help

How to change the attributes of an XML file

hi peeps 'ope you can help me here i need to change the attributes of an xml file, i parse it first using a DOM parser but i cant find a way to change the attributes in the XML file, setAttribute() works only at runtime and doesn't change the attribute in the file itself. I can't find a method that will answer my question. I've searched through the forum and found similar threads....they say in order to write and change the attribute i must use the write() method of the XmlDocument class defined in com.sun.xml.tree.XmlDocument. But, i found another thread, and it says that com.sun.xml.tree.XmlDocument is not safe to use and i should use org.apache.crimson.tree.XmlDocument.....i can't find the XmlDocument class and the API for this package so i really dont know where to start...hope you guys can help me! thnx

thanks for responding roland....i already found the solution...i didn't use the XmlDocument class because i can't find any documents about it except for JAXP 1.0 here is my code snippet...i used the TransformerFactory and Transformer class to write
import org.w3c.dom.*;
import org.w3c.dom.traversal.*;
import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import javax.xml.transform.stream.*;
Document doc = null;
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
dbf.setValidating(false);
doc = db.parse(fileGetFile); //this is the XML file
n1 = (Node)doc.getDocumentElement();
e1 = (Element) n1;
NodeList nodeList = doc.getElementsByTagName ("File");
//just insert whatever you want to do with the XML...parse it..set/change the attribute..etc....sample snippet below changes the attribute downloaded to "no"
for(int iWriteFailed = 0; iWriteFailed <nodeList.getLength() ; iWriteFailed ++){
n2 = nodeList.item(iWriteFailed);
e2 = (Element) n2;
e2.setAttribute("downloaded", "no");}

Hi
I have created a PLSQL package based Oracle Portal
form. This is created a s a databse provider. I have
following questions to check :
1. How to capture return values from the package and
display different messages on success or failure ?
- http://download.oracle.com/docs/cd/B14099_19/portal.1014/b14135/pdg_portletbuilder.htm#BABBAFGI
Step 16
2. How to return to blank form by intializing already
entered values after successfuly process of the form
data.
- http://download.oracle.com/docs/cd/B14099_19/portal.1014/b14135/pdg_portletbuilder.htm#BABGBCHH
thanks
Manjith
