[Sitemaps] SiteMapParser Tika detection doesn't work well on some cases #47

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago

When using the parse method which gets only a sitemap URL, we use Tika to 
detect the Mime type.

On some cases, the detection is bad.

We need to use a better Tika detection.

Use:
new Tika().detect(URL)

Instead of the current:
new Tika().detect(bytes)

Scenario where the bug can be reproduced:
Run the SitemapParser Tool on the following URL:

new Tika().detect(URL) -- Will solve the mentioned problem.

BUT it will cause out library to fetch the sitemap twice.

A better solution should be sought.
Maybe use new Tika().detect(bytes, filename);

Let's instanciate the Tika instance only once and reuse it - otherwise we have 
to reload the Tika config everytime which is definitely not needed. (Julien)

Attached is a patch with the required optimization.

Now the Tika detection is being called with the byte array + filename

The Tika object is being instantiated only once
