javascript - Using Tornado to serve xml formatted with xsl -
i trying have tornado serve xml file , transform using xsl.
i'm using:
xmlhttp.open("get",url,true); , xmlhttp.send(); in javascript/html
self.render("cd_catalog.xml") in python
document.getelementbyid("mydiv").innerhtml=xmlhttp.responsetext; in javascript/html.
the results non-formatted xml file.
why doesn't xsl transform xml? missing?
python:
import os import tornado.httpserver import tornado.ioloop import tornado.web class mainhandler(tornado.web.requesthandler): def get(self): self.render("index.html") class test(tornado.web.requesthandler): def get(self): self.render("cd_catalog.xml") def main(): application = tornado.web.application([ (r"/", mainhandler), (r"/test", test), ]) http_server = tornado.httpserver.httpserver(application) port = int(os.environ.get("port", 5003)) http_server.listen(port) tornado.ioloop.ioloop.instance().start() if __name__ == "__main__": main() js/html:
<!doctype html> <html> <head> <script> function loadxmldoc(url) { var xmlhttp; if (window.xmlhttprequest) {// code ie7+, firefox, chrome, opera, safari xmlhttp=new xmlhttprequest(); } else {// code ie6, ie5 xmlhttp=new activexobject("microsoft.xmlhttp"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readystate==4 && xmlhttp.status==200) { document.getelementbyid("mydiv").innerhtml=xmlhttp.responsetext; } } xmlhttp.open("get",url,true); xmlhttp.send(); } </script> </head> <body> <div id="mydiv"><h2>get list of presidents</h2></div> <button type="button" onclick="loadxmldoc('/test')">ok</button> </body> </html> xml:
<?xml version="1.0" encoding="utf-8"?> <?xml-stylesheet type="text/xsl" href="cd_catalog.xsl"?> <catalog> <cd> <title>empire burlesque</title> <artist>bob dylan</artist> <country>usa</country> <company>columbia</company> <price>10.90</price> <year>1985</year> </cd> . . </catalog> xsl:
<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform"> <xsl:template match="/"> <html> <body> <h2>my cd collection</h2> <table border="1"> <tr bgcolor="#9acd32"> <th>title</th> <th>artist</th> </tr> <xsl:for-each select="catalog/cd"> <tr> <td><xsl:value-of select="title"/></td> <td><xsl:value-of select="artist"/></td> </tr> </xsl:for-each> </table> </body> </html> </xsl:template> </xsl:stylesheet>
tornado didn't apply xsl because didn't ask to. instead, using requesthandler.render(), asked tornado render file tornado template , send result browser. instead, should explicitly run file through xsl processor of choice, , use requesthandler.write() send result browser.
