Description of your issue, suggested solution and other information

Looks like path extraction with categories doesn't work properly. When the link has subcategories such as .../programa_la_voz_de_inaki/... .../seccion_libros/... .../categoria_tecnologia/... .../categoria_ocio_y_cultura/... .../categoria_ciencia/... .../categoria_estilo_de_vida/... .../seccion_gastronomia/... .../categoria_estilo_de_vida/...

Could it be a problem with underscores (_) ?

I think the extractor breaks, not caused by the url but caused for missing tags expected as: "tituloVideo" as is found in the exact line it fails:

elpais.py (line 69) title = self._html_search_regex( (r"tituloVideo\s*=\s*'([^']+)'", webpage, 'title', r'<h2 class="entry-header entry-title.*?>(.*?)</h2>'), webpage, 'title') I'll take a deeper look.

EDIT: Yes, I confirm is when trying to get the title attribute, I'll try to fix this and send a PR.
