Java XPath is a Java API that helps us query XML documents using XPath expressions. Using XPath expressions, random access of elements is possible and hence we can select specific nodes from an XML document. This makes querying the documents more flexible. In this chapter, we have used XPath expressions with predicates such as ‘/cars/carname/@company’, […]

Java XPath parser is an API in Java to parse XML documents using XPath expressions and functions. It helps us to traverse through the entire XML document and obtain elements as nodes inside a NodeList. The package ‘javax.xml.xpath’ provides the API for the evaluation of XPath expressions. In this chapter, we will see how to […]

XPath is an XML Path language to find information in an XML file. It is an official recommendation of the World Wide Web Consortium (W3C). It is used to traverse elements and attributes of an XML document. XPath provides various types of expressions which can be used to enquire relevant information from the XML document […]

Java StAX Parser is a java API which provides interfaces, classes and methods to parse and modify XML documents. Random access of XML elements is not possible using StAX parser and hence, we need to store the required data as the parser parses the XML document. We can use XMLEventReader to read the XML document […]

Java StAX parser is a Java API that provides interfaces to create XML documents. There are cursor APIs such as XMLStreamWriter and Iterator APIs such as XMLEventWriter to create XML documents. In this chapter, we are going to use XMLStreamWriter to create XML documents. This interface has methods such as writeStartDocument(), writeStartElement(), writeCharacters() etc., to […]

Java StAX parser is a Java API which is used to parse XML documents and query the necessary information. This API is event based and hence we need not load entire XML document to query it. As the parser identifies each event, the corresponding action is performed only when the client program implements the event. […]

The Java StAX parser API has classes, methods and interfaces to parse XML documents in the form of events. It is a pull based API that gives the client program more privilege to access the events only if required. In this chapter, we are going to see how to parse an XML documents in Java […]

StAX is a Java-based API to parse XML document in a similar way as SAX parser does. But unlike SAX parser, the StAX parser API is a simple iterator based API that gives parsing control to the client program. It reads the XML document in a forward-only fashion and stores the events in an iterator. […]

Java JDOM parser is an API in java that has classes and interfaces to modify XML documents. This API represents the XML document in the form of a tree structure and each element can be retrieved easily. Hence, modification becomes an easy task. We can use setText() to modify content and addContent() to add new […]

Java JDOM Parser is a Java API that has classes and methods to create XML documents from scratch. We can create a new JDOM document object and add elements, attributes using the methods available in Document and Element interfaces. In this chapter, we are going to use setRootElement(), addContent(), setText() and setAttribute() methods to create […]
