Hello,
I am a newby to both scala and lift. Now that that's out of the way I'm
wondering how to properly use PCDataXmlParser to read and parse html. I
pull data from a restful service by doing the following:
[code]
import dispatch._
import Http._
import net.liftweb.util._;
import scala.xml._;
def upcDatabase(): Box[NodeSeq] = {
val http = new Http
var stream: String = "";
http("http://www.upcdatabase.com/item/0606949324124"; >- (arg => stream =
arg))
stream;
PCDataXmlParser(stream);
}
val feedXML: Box[NodeSeq] = upcDatabase;
[/code]
when doing this I get the following exception:
[exception]
INF: [console logger] dispatch: GET
http://www.upcdatabase.com/item/0606949324124
log4j:WARN No appenders could be found for logger
(org.apache.http.impl.conn.SingleClientConnManager).
log4j:WARN Please initialize the log4j system properly.

What is the proper way to parse non strict html? I thought PCDataXMLParser
allowed for non strict xml as opposed to XML.load().
Thanks,
Chris
