I'm going to assume you're already familiar with the basic "for" loop in Java: for(int i=0; i<10; i++){
System.out.println("i: " + i);
} Well, this works great if you don't need to operate on or with each item within a collection, or if you DO need access to a "counter" variable. A better approach when needing to operate on or with each item within a collection is to use an Iterator : for(Iterator iter = list.iterator(); iter.hasNext();){
Object item = iter.next();
System.out.println(item);... |

Here s an example to show you how to read an XML file in Java via DOM XML parser . The DOM interface is the easiest XML parser to understand, and use. It parses entire XML document and loads it into memory; then models it with Object for easy traversal or manipulation. Note DOM Parser is slow and will consume a lot of memory when it loads an XML document which contains a lot of data. Please consider SAX parser as solution for it, SAX is faster than DOM and use less memory. A DOM XML parser reads... |
I am looking for something like this kind of xml. Some of the things in very short about the DOM parsers 1. Tree of nodes 2. Memory: Occupies more memory, preffered for small XML documents 3. Slower at runtime 4. Stored as objects 5. Programmatically easy 6. Ease of navigation DOM which builds a data tree in memory for easier, non-sequential access to XML data fragments. Now lets jump directly to the example. ******CREATE DOCUMENT OBJECT****** DocumentBuilderFactory dbf = DocumentBuilderFact... |

In Java , we can create XML by using DOM class. Example : This is the XML format you create latter <?xml version="1.0" encoding="UTF-8" ?>
<order>
<orderDetails>
<waiterName>Siridasa</waiterName>
<kitchName>Chines Kitchen</kitchName>
<tableName>20</tableName>
</orderDetails>
<item>
<itemid>ARR01</itemid>

This tutorial is about reading xml file in a java program using the DOM (Document Object Model). The Document Object Model (DOM) is a cross-platform and language-independent convention for representing and interacting with objects in HTML, XHTML and XML documents. Objects under the DOM (also sometimes called Elements ) may be specified and addressed according to the syntax and rules of the programming language used to manipulate them. The rules for programming and interacting with the DOM are sp... |
In this post, I will show how to parse a XML content using DOM parser in Java. There are several DOM implementations available for Java, both inbuilt and external library based. Here, I have used inbuilt simple approach. Following example shows a XML content dynamically created. If it is required to be read from file, then also the process is similar. import java.io.*;

DOM Parser can be used to edit XML data also. We can add elements, remove elements, edit element values, edit attributes in an XML document in java using DOM Parser. <?xml version="1.0" encoding="UTF-8" standalone="no"?>

DOM XML Parser are easiest to understand, it loads the XML object into memory as Document, then you can easily traverse different elements and nodes in the object. The traversing of elements and nodes are not required to be in order. DOM Parser are good for small XML documents but since it loads complete XML file into memory, its not good for large XML files. For large XML files, you should use SAX Parser. In this tutorial we will read the XML file and parse it to create object from it. Here is the... |

A task for a Java project I've been working on called for editing a class to be able to read attributes from XML. It didn't take long to find a solution online, but all of them required the object to be an Element and the existing codebase I was using had its objects stored as Node types. After tinkering in the code for a bit, I went to StackOverflow for an answer Jon Skeet delivered. You have to cast your Node to an Element . Here is some example XML for this problem: <baz>
