Updating xml file using java

18 Aug

This can be done using the set Attribute() method or setting the node Value property of the attribute node.

I have been doing a lot of XML parsing, and manipulation in java lately because I'm building a super dynamic configuration editor for XMS.

XPath comes with powerful expressions that can be used to parse an xml document and retrieve relevant information. In order to understand XPath, first we need to understand basics of DOM parsing in Java. Document Builder Factory builder Factory = Document Builder Instance(); Document Builder builder = null; try catch (Parser Configuration Exception e) In above code, we are parsing an XML file from filesystem.

Java provides powerful implementation of domparser in form of below API. Sometimes you might want to parse XML specified as String value instead of reading it from file.

After using these two methods to modify your XML document, you may want to write the content out as an XML file to disk.

To do so, you need to serialize the // First read the XML file and parse DOMParser parser = new DOMParser(); parser.parse("mydocument.xml"); Document doc = Document(); // Modify the XML ...

XPath x Path = XPath Instance()XPath(); Node start Date Node = (Node) x Path.compile("/data/startdate").evaluate(doc, XPath Constants.So here is what we are going to do:package com.core; import We can add elements, remove elements, edit element values, edit attributes in an XML document in java using DOM Parser. We will learn how to modify or edit this XML file in java program using DOM parser. Now what if I want to update the startdate's month increase by one such as 29/07/2015, 29/8/2015, 20/10/2015 .... Now what if I want to update the startdate's month increase by one such as 29/07/2015, 29/8/2015, 20/10/2015 .... NODE); end Date Text Content("29/07/2015"); Transformer tf = Transformer Instance()Transformer(); Output Property(Output Keys. METHOD, "xml"); Output Property("indent-amount", "4"); DOMSource dom Source = new DOMSource(doc); Stream Result sr = new Stream Result(new File("Data.xml")); tf.transform(dom Source, sr); Hi Mad Programmer, thank you for your answer, I have got the xml part working.
