I have done an advanced search in a web and get some results. For each result I'm interested in extracting 2 fields, "Referencia:" and "CIF".
#This is the url with the results of the search
url="http://www.boe.es/buscar/boe.php?campo%5B1%5D=DOC&dato%5B1%5D=edicto+auto+declaracion+concurso+CIF
&campo%5B6%5D=FPU&dato%5B6%5D%5B0%5D=25%2F04%2F2013&dato%5B6%5D%5B1%5D=30%2F04%2F2013
&sort_field%5B0%5D=fpu&sort_order%5B0%5D=desc&sort_field%5B1%5D=ref&sort_order%5B1%5D=asc&accion=Buscar"
#This is the url of one of the results.
example=http://www.boe.es/buscar/doc.php?id=BOE-B-2013-15895
The CIF field usually of the form X00000000 or X-00000000 with X=c("A","B") and 0=0:9 and The Referencia field is BOE-B-2013-15895 in the example and the CIF B-32210196
