i have a sample xml file
with these tags in it
<siteurl>##</siteurl>
<publisher>###</publisher>
and lots more tags
im writing a program to print the data from the file
like
http://java.sun.com/
sun
instead of printing a whole file
any ideas
It's best to use XSL (and CSS) or XSL-FO for presenting XML data, but if you want to handle XML nodes directly, you can use JAXP as in the following examples.
Parsing an XML document from a fileimport java.io.File;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
...
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder parser = dbf.newDocumentBuilder();
Document doc = parser.parse(new File("foo.xml")); // the XML document the content of which you want to print
...
From this point on the code depends on what you want. Below are a few possibilities.
Getting nodes having a given tag nameString tagName = ... ; // the tag name of the nodes, e.g. "siteurl" or "publisher"
org.w3c.dom.NodeList nodeList = doc.getElementsByTagName(tagName); // all of the nodes having the specified tag name
Getting child nodesNode node = ... ; // the parent node
org.w3c.dom.NodeList nodeList = node.getChildNodes(); // the child nodes
Iterating over the items in a NodeListfor (int i = 0; i < nodeList.getLength(); i++) {
System.out.println(nodeList.item(i).getTextContent().trim());
}
