Ask any programmer and he or she will agree that XML processing is an important part of their coding process. Most of the emerging technologies including the likes of Android also incorporate XML. Java supports XML through JAXP and it also features multiple methods for XML processing. Some of these methods outsource Java development team can use as part of XML processing includes SAX, DOM, TRAX, StAX and JAXB.
Most offshore Java development team use StAX API and its various implementations are available. stAX is a type of a streaming pull-parsing java API that is specifically meant for writing and reading XMLs and it is the perfect alternate to SAX, TrAX and DOM. StAX API is a series of interfaces that provide a framework for bi-directional parser. It provides outsourced Java development team two types of APIs, where one is cursor and the other one is iterator based.
It is important to note for offshore Java developers that these are only a set of interfaces and it is not related to any kind of implementation. Implementations are different and there are different ones available such as stax.codehaus, sjsxp and Woodstock. ...
... It is important to select a StAX implementation because there doesn’t exist any implementation with JDK. Hence, programmers will have to choose a StAX implementation and also download its jar and then add it to the classpath to utlizeStAX API for both writing and reading XMLs. In this scenario Sun/Oracle’s StAX implementation that is bundled in Java EE jar is being used. This can be found as part of glassfish server.
Understanding StAX
StAX: StAX offers a streaming model where it can read as well as write. For instance, if a whole XML document is fed via a tube, at every moment one XML element will come into focus before going to the next element in forward or backward direction. Streaming undoubtedly offers advantages in terms of processing large documents in a sequential manner. It doesn’t matter what is the size of the documents because the performance is not hampered in any way by the size.
Offshore Java development team can make the best use of StAX through parsing WSDL in web services.
XML Parsing through pull and push
Outsource Java developers are aware that there are three parties involved in processing of a XML document. In such a scenario the party one is XML document, second is the API conducting the processing and the third is the client code that uses the API and gets data from the document.
Pull: Client => Parser => XML
Push: Client XML
In pull parsing client code calls the parsing API’s methods to receive data and then the XML is read and parser returns the required data. This process is conducted on demand.
In push parsing, the parser reads the XML document and when the event happens, it pushes the desired data to the client and moves onto the next step. In this type of parsing, it basically acts as an alert. This is how outsourced Java development team can implement Java StAX.
