Class XMLSplitter

java.lang.Object

org.xml.sax.helpers.DefaultHandler

modnlp.util.XMLSplitter

All Implemented Interfaces:

org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler

public class XMLSplitter
extends org.xml.sax.helpers.DefaultHandler

Split an XML file into an "index file" + one or more "include files" corresponding to a selected element of the original file. The parameters on the command line are: - filename: the file to be split (e.g. f.xml) - split_element: the name of the element to go into the split files (e.g. speech) - splitfile_dtd: the DTD for the split file (e.g. epi.dtd) You will need to create epi.dtd by copying the dtd for f.xml to epi.dtd and adding an attribute include to the split_element. For instance, add the following after the speech element: Next you will need to create speech.dtd by copying the speech element specification from the original dtd.
