Parse Page Source and Extract Links
Hi Friends,

I have a bunch of URLs.

Each URL will open up an abstract page.

But, the source contains a link to the main PDF article.

I am looking for a script to do the following task

1. Read input file with URLs.
2. Parse the source and grab all the lines that has the word 'PDF'.
3. Parse the output from step2 and grab only the main links to the PDF articles.
4. Initiate a wget -i command on the links from step3 and grab all the PDFs.


Thanks for any suggestions.

Well, are all the URLs in HREF= clauses?
  1. tool reads lines of one url each and fetches the source to stdout with 'while read u ; do wget $u done'
  2. tool reads html and spits out embedded URLs, maybe stripped of # internal tags (sed,awk,perl).
  3. tool (grep?) filters for PDFs.
  4. tool sorts them unique (sort -u).
  5. tool 'while read u ; do wget $u >dest_dir/${u##*/} done' gets the files.
Add pipes.
