Finding XML files using xalan in Java

Question

I need to write a java application that searches for keywords in tags and actual data from many XML files. From my research on the Internet, I get the feeling that I should use xalan, but I cannot figure out how to use it or what it does. Can someone point me in the right direction? Thanks

Answer 1

The first thing you need to do is decide what data you are going to look for. You say “inside tags and actual data” - does this mean that you do a keyword search for the item name? Or the name of the element and its contents inside?

Answer 4

See this SO post on how to perform a search using the contains()XPath function .

Regarding an example on how to execute an XPath query, I suggest looking at the Java XPath documentation . Here is an example of the code they provide:

XPath xpath = XPathFactory.newInstance().newXPath();
String expression = "/widgets/widget";
InputSource inputSource = new InputSource("widgets.xml");
NodeSet nodes = (NodeSet) xpath.evaluate(expression, inputSource, XPathConstants.NODESET);

This will load the file widgets.xmland return NodeSetall nodes matching the expression.
