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

The PIGrabber class is a SAX ContentHandler that looks for xml-stylesheet processing instructions and tests whether they match specified criteria; for those that do, it creates an InputSource object referring to the relevant stylesheet

`java.lang.String[]` `getStylesheetURIs()` Get the stylesheet URIs as an array of Strings
`void` `processingInstruction(java.lang.String target, java.lang.String data)` Handle xml-stylesheet PI
`void` `setBaseURI(java.lang.String uri)` Set the base URI
`void` `setCriteria(java.lang.String media, java.lang.String title, java.lang.String charset)`
