Parsing invalid ampersands with Android's XmlPullParsers

Question

I am writing a little screen-scraping app that consumes some XHTML - it goes without saying that the XHTML is invalid: ampersands aren\'t escaped as &.<

Answer 1

I was stuck on this for about an hour before figuring out that in my case it was the "&" that couldn't be resolved by the XML PULL PARSER, so i found the solution. So Here is a snippet of code which totally fix it.

void ParsingActivity(String r) {
    try {
        parserCreator = XmlPullParserFactory.newInstance();
        parser = parserCreator.newPullParser();
        // Here we give our file object in the form of a stream to the
        // parser.
        parser.setInput(new StringReader(r.replaceAll("&", "&")));
        // as a SAX parser this will raise events/callback as and when it
        // comes to a element.
        int parserEvent = parser.getEventType();
        // we go thru a loop of all elements in the xml till we have
        // reached END of document.
        while (parserEvent != XmlPullParser.END_DOCUMENT) {
            switch (parserEvent) {
            // if u have reached start of a tag
            case XmlPullParser.START_TAG:
                // get the name of the tag
                String tag = parser.getName();

pretty much what I'm doing I'm just replacing the & with & since I was dealing with parsing a URL. Hope this helps.
