Java XML getElementById returning null, fix using XPath

By -
I had almost lost my breath over this issue for an entire day and found that the solutions provided in most blogs and forums doesn't for a tight schedule. Here, I am sharing the method that finally worked for me. I am using Netbeans with the default DOM parser(SAX Parser) provided in javax package. The problem is that the method: Document.getElementById(String id) returns null unless we explicitly specify the type of an attribute as ID. The Javadoc for this method says: "The DOM implementation must have information that says which attributes are of type ID. Attributes with the name "ID" are not of type ID unless so defined. Implementations that do not know whether attributes are of type ID or not are expected to return null." The type of attributes can be defined in two ways, either by using a DTD or xml schema. But, because I was really in short of time, I didn't want to go through all the complexities of implementing a DTD or XSD validation. Trust me…

Rainbow Storage is a developing paper-based data storage technique first demonstrated by Indian student Sainul Abideen in November 2006. Abideen received his MCA from MES Engineering College inKuttipuram in Kerala's Malappuram district.

Initial newspaper reports of the technology were debunked by multiple technical sources, although Abideen says those reports were based on a misunderstanding of the technology. The paper meant to demonstrate the capability of storing relatively large amounts of data (and not necessarily in the gigabyte range) using textures and diagrams. The Rainbow data storage technology claims to use geometrical shapes such as triangles, circles and squares of various colors to store a large amount of data on ordinary paper or plastic surfaces. This would provide several advantages over current forms of optical- or magneticdata storage like less environmental pollution due to the biodegradability of paper, low cost and high capacity. Data could be stored on &quo…

Any software development process is divided into several logical stages that allow a software development company to organize its work efficiently in order to build a software product of the required functionality within a specific time frame and budget. A professional software development team has an opportunity thorough planning and a well-thought organization of a software development process eliminate unnecessary risks or reduce them to the minimum.

A typical software development lifecycle comprises the following stages:Documentation of software development.Designing a software product.Implementing the software product.Testing the software solution.Deployment of the solution.Maintenance of the product.  Software development teams, taking into account its goals and the scale of a particular project, have a number of well-established software development models to choose from. Therefore, each software development company adopts the best-suited model, which facilitates the…
