Parte II. Raspado avanzado
Ya has sentado algunas bases para el raspado web; ahora viene la parte divertida. Hasta este punto, tus raspadores web han sido relativamente tontos. Son incapaces de recuperar información a menos que el servidor se la presente inmediatamente en un formato atractivo. Toman toda la información al pie de la letra y la almacenan sin analizarla. Se tropiezan con los formularios, la interacción con el sitio web e incluso con JavaScript. En resumen, no sirven para recuperar información a menos que esa información realmente quiera ser recuperada.
Esta parte del libro te ayudará a analizar los datos en bruto para obtener la historia que hay debajo de los datos: la historia que los sitios web suelen ocultar bajo capas de JavaScript, formularios de inicio de sesión y medidas contra el raspado. Aprenderás a utilizar raspadores web para probar tus sitios, automatizar procesos y acceder a Internet a gran escala. Al final de esta sección, tendrás las herramientas para recopilar y manipular casi cualquier tipo de datos, en cualquier forma, a través de cualquier parte de Internet.
