Quick Scraper Node Question (1 Viewer)

Hello,

how and is it possible to tell the scraper if first retrieve/parse page gives no resut than use the second one. Same vice versa means if first gives a result don't use the second one?

I hope you understand...

Thanks

Schenk

Sorry, don't understand, can you elaborate maybe using the site you're scripting as an example?

Okay i´ll try:

    <retrieve name="links_page_com" url="http://www.cinefacts.de/kino/film/${movie.site_id}/${movie.title}/externe_links.html"/>
     <parse name="imdb_com" input="${links_page_com}" regex="${rx_imdb_com}"/>
      <if test="${imdb_com[0][0]!=">
       <set name="movie.imdb_id" value="${imdb_com[0][0]}"/>
      </if>

    <retrieve name="links_page_de" url="http://www.cinefacts.de/kino/film/${movie.site_id}/${movie.title}/externe_links.html"/>
     <parse name="imdb_de" input="${links_page_de}" regex="${rx_imdb_de}"/>
      <if test="${imdb_de[0][0]!=">
       <set name="movie.imdb_id" value="${imdb_de[0][0]}"/>

If the result is found in the first try then set name, if no result is found, try second one and if found set name .

Hope this makes sens to you now

Thanks

Schenk

Just wrap the bottom section in an <if> node like this:

<if test="${imdb_com[0][0]=">
</if>
