#9 InputSource with InputStream NPE

[Anonymous]

If I create an InputSource using an InputStream and
then pass that to the parser I get an NPE:

java.lang.NullPointerException
at
hotsax.html.sax.HtmlLexer.yy_advance(HtmlLexer.java:434)
at hotsax.html.sax.HtmlLexer.yylex(HtmlLexer.java:608)
at hotsax.html.sax.HtmlLexer._yylex(HtmlLexer.java:227)
at hotsax.html.sax.HtmlParser.yylex(HtmlParser.java:377)
at hotsax.html.sax.HtmlParser.yyparse(HtmlParser.java:602)
at hotsax.html.sax.SaxParser.parse(SaxParser.java:219)
[remainer of trace omitted]

If I use a Reader instead then the parser works fine.

I have the exact same BUG (HotSAX-0.1.2c.tar.gz) by passing
an InputSource created from a File.toURI().toString(). The
file exists.

Pretty frustrating...

You need to wrap whatever raw input you have with a reader.

So for a file you use FileReader:

InputSource input = new InputSource(
new BufferedReader(
new FileReader( "src/test/resources/smithsonianmag.com.santas-trusty-robot-reindeer.html")));

For a string you use a StringReader:

String html = "<x>\n" +
"Text\n" +
"<!-- comment -->\n" +
"</x>";
InputSource input = new InputSource(new StringReader(html));

for a URL you use a InputStreamReader:

File file = new File("src/test/resources/smithsonianmag.com.santas-trusty-robot-reindeer.html");

@SuppressWarnings("deprecation")
URL fileUrl = file.toURL();

TextExtractionContextHandler ch = new TextExtractionContextHandler("p");
parser.setContentHandler(ch);
InputSource input = new InputSource(
new BufferedReader(
new InputStreamReader(
fileUrl.openStream())));
