It's quite simple to write if you are not satisfied with one of the several solutions mentioned. For the record, with Python, you can do it as simply as: #!/usr/bin/python from xml.dom import ext from xml.dom.ext.reader import PyExpat from xml.xpath import Evaluate if __name__ == '__main__': import sys if len(sys.argv) < 3: print "Usage: xpath expression file ..." sys.exit(1) expr = sys.argv for fileName in sys.argv[2:]: #build a DOM tree from the file reader = PyExpat.Reader() xml_dom_object = reader.fromUri(fileName) retval = Evaluate(expr, xml_dom_object.documentElement) if len(retval): print "Document %s meets our criteria (\"%s\" found %d times)" % (fileName,expr,len(retval)) else: print "Document %s does NOT meet our criteria (\"%s\" not found)" % (fileName,expr) #reclaim the object reader.releaseNode(xml_dom_object) XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
