Parse XML file with regex

Hi,
Is that possible to parse a xml file using regular expressions....if s what is the API needed
thanx in advance

Is that possible to parse a xml file using regular
expressions....if s what is the API neededI'm sure it can be done. Here's the regex API:
http://java.sun.com/j2se/1.5.0/docs/api/java/util/regex/package-summary.html
http://www.javaregex.com/tutorial.html
But that's not where regex is for. Better have a look at this:
http://java.sun.com/xml/

How to parse XML file with namesapce?

Hi,
   I am trying to parse an xml file having namespace. But no data is returned.
Sample Code:
public class XMLFileLoader
var xml:XML = new XML();
var myXML:XML = new XML();
var XML_URL:String = "file:///C:/Documents and Settings/Administrator/Desktop/MyData.xml";
var myLoader:URLLoader = null;
public function XMLFileLoader()
var myXMLURL:URLRequest = new URLRequest(XML_URL);
myLoader= new URLLoader(myXMLURL);
myLoader.addEventListener(Event.COMPLETE,download);
public function download(event:Event):void
myXML = XML(myLoader.data);
var ns:Namespace=myXML.namespace("xsi");
for(var prop:String in myXML)
     trace(prop);
//Alert.show(myXML..Parameters);
//trace("Data loadedww."+myXML.toString());
//Alert.show(myXML.DocumentInfo.attributes()+"test","Message");
The XML Contains the following format.

Any sample code how to parse this kind of xml file with namespaces...

i have exactly the same problem with KXml2, but using a j2me-polish netbeans project.
i've tried to work around with similar ways like you, but none of them worked. now i've spent 3 days for solving this problem, i'm a bit disappointed :( what is wrong with setting the downloaded kxml2 jar path in libraries&resources?

Parsing XML file with different languages (Xerces)

How do we code or program to an XML file with different
languages , say english and spanish. WHen we parse such a document with the default locale , the presence of special characters throws errors .For eg when I use xerces and use
DOMParser parser = new DOMParser();
try
// Parse the XML Document
parser.parse(xmlFile);
catch (SAXException se)
se.printStackTrace();
org.xml.sax.SAXParseException: An invalid XML character (Unicode: 0xfc) was found in the element content of the document.
System Error: void org.apache.xerces.framework.XMLParser.parse(org.xml.sax.InputSource)
So what locale do we set before we parse ?How to handle this problem

You need an encoding attribute in the xml declaration. If you don't, the parser assumes UTF-8, which are ASCII characters up to 127 - useful (only) for English.
So, something like this would allow you to use characters above 127, ISO-8859-1 is the encoding used by standard PCs.
<?xml version="1.0" encoding="ISO-8859-1"?>
You can find a (offical) list of encodings at:
http://www.iana.org/assignments/character-sets
I'm not sure about mixing various encodings. I think you have to resort external parsed entities, which can have their own encoding, but I think you cannot mix encodings in one XML file.
Good luck.

Parsing XML file with the word "Infinity" in it

I am having a problem within Flex that parses an XML file,
one of the text names within the file contains the word "Infinity".
Unfortunately this is a constant within Flex and the element of my
array does not think it is a text string but a value. I have tried
type setting the xml element, and putting escape characters around
the text but nothing works. If I change the text to lowercase
"infinity" it works fine.
Any help greatly appreciated.

This sounds like a bug. Can you file it, with a small code
example that illustrates it, here:

Thanks!

Parse exisitng xml file and recreate another xml file with different struct

Is it possible in java using dom parser to parse an exisiting xml file and recreate a new xml file from data obtained by parsing old xml file.
I checked on old forum threads and everywhere either parsing xml file has been explained or creating new xml file from scratch has been shown.
Any examples/guidance will be appreciated....

The general process is:
Document dom1 = ... // the parsed document
Document dom2 = ... // new document constructed on the fly
Node nD1 = ... // some random node found in dom1
// copy the node from dom1 and associate with dom2
Node nD2 = dom2.importNode(nD1, true);
// ... treat nD2 as a node which can now be inserted into dom2 ...
Node otherD2 = ... // some other node already in dom2
otherD2.appendChild(nD2);Note, in this example the nD1 node is copied (including any sub-nodes) into a new node, nD2. You can alternately move the node from one Document to another using Document.adoptNode(), however this may fail (see the javadoc).

Reading xml file with sax parser: unknown protocol: c

Hi,
I've been googling around, and the best I can find is that the file name:
File test = new File("lib/test/parseTest/validate-test.xml");should be a url:
File test = new File("File://lib/test/parseTest/validate-test.xml");but I'm working on a linux machine and can't put "File://c:/pathToFile/file.xml"
Also, I did some testing and I can read a small xml file with just a few elements, but on large complex files, I get that error.
anyone ever run into this before?

No, that's wrong. The parameter for that constructor is a file path (relative or absolute). Not a URL. You must have misunderstood whatever you read.
but I'm working on a linux machine and can't put "File://c:/pathToFile/file.xml"What kind of a Linux machine is this which has a C drive? You must have misunderstood whoever told you to do that.

How can I save a XML file with JAXP1.1?

Dear All.
I write a program to create XML file with DOM model, but I can't know how to save it? My environment is JAXP1.1 and JDK1.3.1,I has been required not use other XML parser toolkits,only JAXP1.1.
How can I do? thank you.
Many person give me a idea the com.sun.xml.tree.XmlDocument, but I can't find the class in API document or JAXP1.1's packages. why?
what is it? How can i use it?
thank you very much.

The way to save an XML Document is using a Transformer.
To have access to a transformer use the packages :
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import javax.xml.transform.stream.*;
Then for saving your Document Object (named dXml) get a Transformer Object with the TransformerFactory Object :
TransformerFactory tf = TransformerFactory.newInstance();
Transformer t = tf.newTransformer();
Now you have got your Transformer Object, to save your Document Object use the method :
Document dXml = getMyDocument(); // this is your Document Object.
OutputStream osSave = getMySaveStream(); // this the OutputStream you need to save your Document.
try
t.transform(new DomSource(dXml), new StreamResult(new OutputStreamWriter(osSave)));
finally
osSave.close();
And your Document was now saved.

Generation of Xml file with java output

Hi i m new to xml and java combination. I have a name value pair kind of output returning from java program. I want to generate the new xml file with the data. Could some one help me out in generating xml file with the data. Could anyone send me the java code that does this task.

Let me know which parser are you using currently for reading xml files so that i assist you. For now, you can refer to STAX Parser API under this link

Create xml file with values from context

Hi experts!
I am trying to implement a WD application that will have some input fields, the value of those input fields will be used to create an xml file with a certain format and then sent to a certain application.
Apart from this i want to read an xml file back from the application and then fill some other context nodes with values from the xml file.
Is there any standard used code to do this??
If not how can i do this???
Thanx in advance!!!
P.S. Points will be rewarded to all usefull answers.

Hi,
you need to create three util class for that:-
XMLHandler
XMLParser
XMLBuilder
for example in my XML two tag item will be there e.g. Title and Organizer,and from ur WebDynpro view you need to pass value for the XML tag.
And u need to call buildXML()function of builder class to generate XML, in that i have passed bean object to get the values of tags. you need to set the value in bean from the view ui context.

Transfer 100M XML file with XSL

Hi,
I am trying to transfer 100M XML file with XSL. Input.xml is the XML file, format.xsl is the XSL file. I type in the command line as:
java org.apache.xalan.xslt.Process -IN input.xml -XSL format.xsl -OUT output.xml
It got "out of memeory" error. My questions are:
1. Is it possible to transfer such large XML file with XSLT?
2. The XSL processor used SAX or DOM to parse XML file?
3. Any suggestions?
Thanks.
James

maybe?
java -Xmx200m org.apache.xalan.xslt.Process -IN input.xml -XSL format.xsl -OUT output.xml

Combine several XML files with same structure

Hello,
I have several XML files with the same structure and I want to combine them and create a new XML file to be bale to compare that information easily. It does not look very difficult but as I am very new in this I am not bale to get it
The structure of my actual files would be something simlar to:
Root->...-> Name->Address, Telephone
And what I would like to have si something like
Root->.... ->Address-> Name 1,Name 2....
Root -> ...->Telephone-> Name 1, Name 2....
Does anyone know how to do this.
Thanks

You could write a XSL transformation file that does this and transform your input file via
     * Transform XML file with a style sheet.
     * <p><b>Example:</b><p>
<table align="center" bgcolor="#E0E0E0" border=1 cellpadding="10" cellspacing="0"><tr><td><pre style="margin-top:0; margin-bottom:0">
XMLTransformer t = new XMLTransformer();
FileOutputStream fos = new FileOutputStream("C:/Project/result.html");
String xmlFile = "C:/Project/source.xml";
String styleSheet = "C:/Project/stylesheet.xsl";
t.transform(xmlFile, styleSheet, fos);
</pre></td></tr></table>
     * @param xmlfile The XML file to transform.
     * @param style Stylesheet to use for transformation.
     * @param outputStream OutputStream to write the transformed result to.
    public void transform(String xmlfile, String style, OutputStream outputStream) {
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        //factory.setNamespaceAware(true);
        //factory.setValidating(true);
            //todo: use inputstreams instead of file names
            try {
                File stylesheet = new File(style);
                File datafile   = new File(xmlfile);
                DocumentBuilder builder = factory.newDocumentBuilder();
                document = builder.parse(datafile);
                // Use a Transformer for output
            TransformerFactory tFactory = TransformerFactory.newInstance();
            StreamSource stylesource = new StreamSource(stylesheet);
            Transformer transformer = tFactory.newTransformer(stylesource);
            DOMSource source = new DOMSource(document);
            StreamResult sr = new StreamResult(outputStream);

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.
thanks

Problems with reading XML files with ISO-8859-1 encoding

Hi!
I try to read a RSS file. The script below works with XML files with UTF-8 encoding but not ISO-8859-1. How to fix so it work with booth?
Here's the code:
import java.io.File;
import javax.xml.parsers.*;
import org.w3c.dom.*;
import java.net.*;
* @author gustav
public class RSSDocument {
    /** Creates a new instance of RSSDocument */
    public RSSDocument(String inurl) {
        String url = new String(inurl);
        try{
            DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
            Document doc = builder.parse(url);
            NodeList nodes = doc.getElementsByTagName("item");
            for (int i = 0; i < nodes.getLength(); i++) {
                Element element = (Element) nodes.item(i);
                NodeList title = element.getElementsByTagName("title");
                Element line = (Element) title.item(0);
                System.out.println("Title: " + getCharacterDataFromElement(line));
                NodeList des = element.getElementsByTagName("description");
                line = (Element) des.item(0);
                System.out.println("Des: " + getCharacterDataFromElement(line));
        } catch (Exception e) {
            e.printStackTrace();
    public String getCharacterDataFromElement(Element e) {
        Node child = e.getFirstChild();
        if (child instanceof CharacterData) {
            CharacterData cd = (CharacterData) child;
            return cd.getData();
        return "?";
}And here's the error message:

I read files from the web, but there is a XML tag
with the encoding attribute in the RSS file.If you are quite sure that you have an encoding attribute set to ISO-8859-1 then I expect that your RSS file has non-ISO-8859-1 character though I thought all bytes -128 to 127 were valid ISO-8859-1 characters!
Many years ago I had a problem with an XML file with invalid characters. I wrote a simple filter (using FilterInputStream) that made sure that all the byes it processed were ASCII. My problem turned out to be characters with value zero which the Microsoft XML parser failed to process. It put the parser in an infinite loop!
In the filter, as each byte is read you could write out the Hex value. That way you should be able to find the offending character(s).

I have a java program which will parse this xml file using an xsl file and will produce another xml file as desired by me .This new xml file format will be defined in the xsl file as follows
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" >
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
<?xml version="1.0" encoding="UTF-16"?>
<businessnews>
<xsl:for-each select="root/nitf">
<story>
<h1 color="RED">
<headline>Headline<xsl:value-of select='mitem_maintitle'/></headline>
<author>Author</author>
<summary>Summary<xsl:value-of select='mitem_summary'/></summary>
<article>Article</article>
<date>Date<xsl:value-of select='published_date'/></date>
<category>Category<xsl:value-of select='el_topics/main_topic_desc'/></category>
</h1>
</story>
</xsl:for-each>
</businessnews>
</xsl:template>
</xsl:stylesheet>
Now it is always giving the error message as follows
The processing instruction target matching "[xX][mM][lL]" is not allowed.
Hoping for a positive reply
Thanks
