hihi i'm a newbe in Java. If u don't mind, please show me basic code to create an XML file (i understood XML structure), how to retrieve data from this file and write data to it. I need to develop my application in "Eclipse.exe".

Follow your instruction i read on "http://developerlife.com/xmljavatutorial1/default.htm" and see this coding:

import com.sun.xml.tree.*;<br />
import org.w3c.dom.*;

You must have the a String URL of the XML document before you can instantiate a DOM object from it. Assume that an XML file called AddressBook.xml is at the following URL:
http://beanfactory.com/xml/AddressBook.xml. Here is the code to create a DOM object from this URL:

try <br />
{    <br />
String url =  "http://beanfactory.com/xml/AddressBook.xml";    <br />
Document doc =         XmlDocumentBuilder.createXmlDocument(url);<br />
}<br />
catch(Exception e){}

But i can not download Sun's parser or IBM's parser.

Can u tell me another way : )

Also, I am really a C++ programmer with a little Java programming knowledge. So, I cannot really give a good example using Eclipse.

Simply spoken a XML Schema describes a set of elements and attributes and how these are allowed to be nested. Each XML file that claims to conform to the Schema has to follow these rules.
In your case the Schema has nothing to do with the storing process itself, but it gives you the possibility to validate whether your storage file (still) has the expected structure/content.
Out there are many tutorials on XML and XML Schema that can be easily found with google or the search engine of your choice. I suggest you read some of them, try to solve the problem on your own and come back if you get stuck at some point.

Well your best bet would be to use an instance of XmlDocument class that gives you a DOM representation of your XML file and add nodes to it according to the structure of your XML. Take a look at the MSDN documentation for the XmlDocument class which provides some examples and many links for further reading.

If you're using DOM to access the XML file you can simply iterate over the child nodes of a given node starting with the document's root node.

XML is *great* for configuration files, and, of course, for data exchange between different applications. About every configurable application that exports or imports data will benefit from XML.

Either enable the "Ignore HTML tags in this message" checkbox beneath the smilies or replace all < with <, cause otherwise we see neither your schema nor the xml fragment.

XPath war

Hey guys, i'm fearly new to xml (espacially xpath) and need a little help here..

My XML document looks like

<br />
<?xml version="1.0" encoding="ISO-8859-1" ?><br />
< Properties><br />
  < Property><br />
    <Number>10</Number><br />
    <Type>Type A</TypeNL><br />
    <Description>A nice description</Description><br />
  </Property><br />
</Properties><br />

(added spaces in front of the Properties and Property element, because else they appear as smiley)

I'm trying to loop through all properties (ofcourse in my xml document there are more than one properties) and would like to retrieve the number, type and description of the property. I'm writing my app in C#

<br />
XPathDocument docRegion = new XPathDocument(_XmlFilePath);<br />
XPathNavigator navRegions = docRegion.CreateNavigator();<br />
XPathNodeIterator nodeProperty = navRegions.SelectChildren("//Properties/Property", "");<br />

I would expect the SelectChildren function to return a collection of all properties in my XML document, but i'm not getting the expected values returned. Am I doing something wrong, do I need a diffrent approach or something??

You can enable the "Ignore HTML tags in this message" checkbox beneath the smilies to easily post XML fragments. Unfortunately this also disables the other formatting possibilities, but most times it's far more practically than inserting spaces or replacing < with <.

Eduard Keilholz wrote:

Documentation says that SelectChildren selects only directly nested children and the first parameter should be a local name and no XPath expression. So either change the first parameter to "Property" (not sure if this works cause I'm not sure whether "Properties" is the current node of the the XPathNavigator) or use the Select method which allows the use of XPath expressions.

I thought this would filter all html tags which disables me to insert xml

I never thought about it, but the checkbox label could be misinterpreted the way you did. Maybe "Treat HTML tags and there content as plain text" would be more precise.

Either check the "Ignore HTML tags in this message" checkbox beneath the smilies or replace all < with <, so we can see what tag you're talking about.
The value of the version attribute tells you exactly what the name implies: the version of the XML standard the document conforms to.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
