Replacing XML in File from "Document" in Java
- by poeschlorn
Hi,
after processing my first steps in working with XML in java I am now at the point where I want to update some data in my XML/GPX file...
Reaplacing it in my "Document" data type works great :)
How here comes the question: how can I store the changed "document"-model back to my file? Do I have to do this by using the standart file-functions (via steams and so on) oder is the a more elegant way to do this? ;-)
Here's the code I already worked out, maybe that could help. (the method getParsedXML is just puting the conversion from the file into an extra method)
Document tmpDoc = getParsedXML(currentGPX);
//XML Parsind tests:
// Access to tag attribute <tag attribut="bla">
System.out.println(tmpDoc.getElementsByTagName("wpt").item(0).getAttributes().getNamedItem("lat").getTextContent());
// Access to the value of an child element <a><CHILD>ValueOfChild</CHILD></a>
System.out.println(tmpDoc.getElementsByTagName("wpt").item(0).getChildNodes().item(5).getTextContent());
// Replacing access to tag attribute
tmpDoc.getElementsByTagName("wpt").item(0).getAttributes().getNamedItem("lat").setTextContent("139.921055008");
System.out.println(tmpDoc.getElementsByTagName("wpt").item(0).getAttributes().getNamedItem("lat").getTextContent());
// Replacing access to child element value
tmpDoc.getElementsByTagName("wpt").item(0).getChildNodes().item(5).setTextContent("Cala Sant Vicenç - Mallorca 2");
System.out.println(tmpDoc.getElementsByTagName("wpt").item(0).getChildNodes().item(5).getTextContent());
