Xml Parsing with Dom4j
University at Buffalo Hanifi Gunes Spring 2011 PhD Candidate Computer Science & Engineering CSE 586 - Distributed Systems hanifigu{at}buffalo{dot}edu xml parsing with dom4j In this tutorial we will talk about XML parsing with dom4j, an easy to use, open source library working with XML, XPath and XSLT on the Java platform. So let’s get started. ➀ Download and install eclipse for Java developers: http://www.eclipse.org Download the dom4j jar package: http://dom4j.sourceforge.net Download the jaxen jar package: http://jaxen.codehaus.org ➁ Run eclipse and locate your workspace directory if you are running it for the first time. Now, create a new Java Project, MyXMLReader, from File ➝ New ➝ Java Project. Notice that the project is created under the workspace directory {workspace_dir}/MyXMLReader. ➂ Right click on your project and select Build Path ➝ Add External Archives. Locate and add the dom4j jar archive from step 1 and repeat the same procedure to add the jaxen package to your build path. At that point, you should see these packages listed under Referenced Libraries as it is on the left snapshot. ➃ Now that, the project setup is done we can work with Yahoo! Weather. Visit http:// developer.yahoo.com/weather/ to get familiar with the XML response schema. First thing to observe is that you can query Yahoo Weather for a particular zip code using the following pattern http://weather.yahooapis.com/forecastrss?p=ZIPCODE. Try substituting your own zip code into the address pattern and then navigate to that address from your browser in order to inspect the XML response. -

XSLT in Context
XSLT in Context This chapter is designed to put XSLT in context. It's about the purpose of XSLT and the task it was designed to perform. It's about what kind of language it is, and how it came to be that way; and it's about how XSLT fits in with all the other technologies that you are likely to use in a typical web-based application. I won't be saying much in this chapter about what an XSLT stylesheet actually looks like or how it works: that will come later, in Chapters 2 and 3. I shall begin by describing the task that XSLT is designed to perform – transformation – and why there is the need to transform XML documents. I'll then present a trivial example of a transformation in order to explain what this means in practice. The chapter then moves on to discuss the relationship of XSLT to other standards in the growing XML family, to put its function into context and explain how it complements the other standards. I'll describe what kind of language XSLT is, and delve a little into the history of how it came to be like that. If you're impatient you may want to skip the history and get on with using the language, but sooner or later you will ask "why on earth did they design it like that?" and at that stage I hope you will go back and read about the process by which XSLT came into being. Finally, I'll have a few things to say about the different ways of using XSLT within the overall architecture of an application, in which there will inevitably be many other technologies and components each playing their own part. -
JAVA XML Interview Questions
JJAAVVAA XXMMLL -- IINNTTEERRVVIIEEWW QQUUEESSTTIIOONNSS http://www.tutorialspoint.com/java_xml/java_xml_interview_questions.htm Copyright © tutorialspoint.com Dear readers, these JAVA based XML Parsing Interview Questions have been designed specially to get you acquainted with the nature of questions you may encounter during your interview for the subject of JAVA based XML Parsing. As per my experience good interviewers hardly plan to ask any particular question during your interview, normally questions start with some basic concept of the subject and later they continue based on further discussion and what you answer − What XML stands for? XML stands for Extensible Markup Language. What are the advantages of using XML? Following are the advantages that XML provides − Technology agnostic - Being plain text, XML is technology independent. It can be used by any technology for data storage and transmission purpose. Human readable- XML uses simple text format. It is human readable and understandable. Extensible - in XML, custom tags can be created and used very easily. Allow Validation - Using XSD, DTD and XML structure can be validated easily. What are the disadvantages of using XML? Following are the disadvantages of XML usage − Redundant Syntax - Normally XML file contains lot of repeatitive terms. Verbose-Being a verbose language, XML file size increases the transmission and storage costs. What is XML Parsing? Parsing XML refers to going through XML document to access data or to modify data in one or other way. What is XML Parser? XML Parser provides way how to access or modify data present in an XML document. Java provides multiple options to parse XML document. -
Designing of an Xpath Engine for P2P XML Store
Designing of an XPath Engine for P2P XML Store Jovic, Darko; and Milutinovic, Veljko We can use XPath engine which works with Abstract— In the introductory part, this paper generic DOM and use it on top of P2P DOM defines the general environment for this research layer. This way we get full XPath functionality, but and defines the terms of interest. Then we define query execution is performed locally. All required the research problem: How to perform distributed node sets are pulled from the community and XPath query execution in a P2P environment. nodes matched against query to get the result. Existing solutions to the problem are briefly surveyed, and their drawbacks are underlined; Getting node sets from the community in case of each surveyed piece of research is analyzed large XML documents can cause increased according to the same template. Then, the essence communication among local peer and other of the proposed solution is presented: peers which contain node sets for specific implementation of an XPath engine which works in documents. High communication traffic can be a P2P environment and performs distributed avoided by distributing XPath query execution. query execution. The conclusion is from the point of view of performance/complexity ratio. 1. INTRODUCTION PATH is a language for addressing parts of X an XML document, designed to be used by both XSLT and XPointer [1][4]. XPath expressions are used to query XML data, express transformations and reference elements in remote documents. XPath is specification language designed by the World Wide Web Consortium (W3C) [6]. It is an expression language for addressing parts of an XML document, used by various XML Figure 1: Peer-to-Peer XML Storage System technologies such as XSL Transformation (XSLT) and XML Pointer Language (XPointer). -
A Performance Based Comparative Study of Different Apis Used for Reading and Writing XML Files
A Performance Based Comparative Study of Different APIs Used for Reading and Writing XML Files A Thesis submitted to the Graduate School at the University of Cincinnati In Partial Fulfillment of the requirements for the Degree of MASTER OF SCIENCE In the School of Electronics and Computing Systems of the College of Engineering and Applied Sciences By Neha Gujarathi Bachelor of Engineering (B. E.), 2009 University of Pune, India Committee Chair: Dr. Carla Purdy ABSTRACT Recently, XML (eXtensible Markup Language) files have become of great importance in business enterprises. Information in the XML files can be easily shared across the web. Thus, extracting data from XML documents and creating XML documents become important topics of discussion. There are many APIs (Application Program Interfaces) available which can perform these operations. For beginners in XML processing, selecting an API for a specific project is a difficult task. In this thesis we compare various APIs that are capable of extracting data and / or creating XML files. The comparison is done based on the performance time for different types of inputs which form different cases. The codes for all the different cases are implemented. Two different systems, one with Windows 7 OS and another with Mac OS are used to perform all the experiments. Using the results found we propose a suitable API for a given condition. In addition to the performance, programming ease for these APIs is taken into consideration as another aspect for comparison. To compare the programming ease, aspects such as number of lines of code, complexity of the code and complexity of understanding the coding for the particular API are considered. -
XML Retrieval with Results Clustering on Android

The idea of mining XML However, traditional XML retrieval does not work on mobile documents anywhere and anytime is very amazing but not devices due to the mobile platforms’ limitations and diversities. crazy. Clustering XML data is more complicated than common Considering that XML retrieval on mobile devices will text data as XML allows inserting structural and conceptual become increasingly popular, in this article, we have paid aspects into document content. An XML document includes attention to the design and implementation of XML retrieval tags and data; while tags describing names of elements and results clustering model on the android platform, building on jaxen and dom4j, the XML parser and retrieval engine; contain concepts as text data. Besides that, structure tags also furthermore, the K-means clustering algorithm. show the relationship between elements. Now, research work dedicated to XML document As an example of usage, we have tested the prototype on clustering mainly has three types, including structure-based some data sets to the mobile scenario and illustrated the method, content-based method and combination of both. -
Building Workflow Applications with XML and Xquery
Building Workflow Applications with XML and XQuery By: Dr. Michael Kay In my previous articles, I introduced some of the mechanics of coding with XQuery and XSLT 2.0 — in a rapid progression from novice to advanced level I started with a brief ten-minute introduction to XQuery, went on from there to explore FLWOR expressions in some depth, and then exposed you to the wonderful benefits of writing schema-aware XSLT and XQuery code. In this article I'm going to stick with the assumption that you're a fast learner, and assume that you've now advanced beyond the coding level and are designing entire applications. (Actually, I don't really think of this as a hierarchy. Coders are the people who make the biggest difference to an IT system, which is why I decided five years ago after years of doing architecture and design that it was time to get back to coding. But application architecture is important too.) In this article I want to explore the role of XML in workflow applications. I'm using the term workflow in a very general kind of way, to describe applications that one can think of in terms of documents moving around a community of people who each perform particular tasks. Processing an insurance claim, or a bug report, or a capital requisition are examples that come to mind. Many processes in publishing can be viewed as workflow applications, and one also can use the idea for a spectrum of business processes from the very everyday (like processing an invoice or scheduling a meeting) to the very complex and soft (like acquiring another company). -
Java API for XML Processing (JAXP)
Java API for XML Processing (JAXP) • API that provides an abstraction layer to XML parser implementations (specifically implementations of DOM and SAX), and applications that process Extensible Stylesheet Language Transformations (XSLT) • JAXP is is a layer above the parser APIs that makes it easier to perform some vendor-specific tasks in a vendor-neutral fashion. JAXP employs the Abstract Factory design pattern to provide a plugability layer, which allows you to plug in an implementation of DOM or SAX, or an application that processes XSLT • The primary classes of the JAXP plugability layer are javax.xml.parsers.DocumentBuilderFactory, javax.xml.parsers.SAXParserFactory, and javax.xml.transform.TransformerFactory. • Classes are abstract so you must ask the specific factory to create an instance of itself, and then use that instance to create a javax.xml.parsers.DocumentBuilder, javax.xml.parsers.SAXParser, or javax.xml.transform.Transformer, respectively. • DocumentBuilder abstracts the underlying DOM parser implementation, SAXParser the SAX parser implementation, and Transformer the underlying XSLT processor. DocumentBuilder, SAXParser, and Transformer are also abstract classes, so instances of them can only be obtained through their respective factory. JAXP Example - 1 import java.io.*; import javax.xml.*; import org.w3c.dom.Document; import org.xml.sax.SAXException; import javawebbook.sax.ContentHandlerExample; public class JAXPTest { public static void main(String[] args) throws Exception { File xmlFile = new File(args[0]); File -
