[jira] [Created] (NUTCH-1250) parse-html does not parse links with empty anchor

parse-html does not parse links with empty anchor
-------------------------------------------------

                 Key: NUTCH-1250
                 URL: https://issues.apache.org/jira/browse/NUTCH-1250
             Project: Nutch
          Issue Type: Bug
          Components: parser
    Affects Versions: 1.4
            Reporter: Andreas Janning


The parse-html plugin does not generate an outlink if the link has no anchor
For example the following HTML-Code does not create an Outlink:
{code:html} 
  <a href="example.com"></a>
{code}

The JUnit-Test TestDOMContentUtils tries to test this but fails since there is a comment inside the <a>-Tag.
{code:title=TestDOMContentUtils.java|borderStyle=solid}
new String("<html><head><title> title </title>"
        + "</head><body>"
        + "<a href=\"g\"><!--no anchor--></a>"
        + "<a href=\"g1\"> <!--whitespace-->  </a>"
        + "<a href=\"g2\">  <img src=test.gif alt='bla bla'> </a>"
        + "</body></html>"), 
{code}

When you remove the comment the test fails.

{code:title=TestDOMContentUtils.java Test fails|borderStyle=solid}
new String("<html><head><title> title </title>"
        + "</head><body>"
        + "<a href=\"g\"></a>" // no anchor
        + "<a href=\"g1\"> <!--whitespace-->  </a>"
        + "<a href=\"g2\">  <img src=test.gif alt='bla bla'> </a>"
        + "</body></html>"), 
{code}
