Since HTML is very similar to XML, you may use an xml tool to parse your file.

Since your HTML-File is not fully standards compliant, the parser complains about it and the file has either be adapted by hand to be compliant or to be preprocessed prior to the parsing. The <br> is the problematic element. Compliant would be <br/> with a slash within the tag.

So you can do it with an xmlparser like xmlstarlet in three steps:

Code:
sed 's|<br>|<br/>|gi' data.html      |
  xmlstarlet sel -t -v '//body/div/p'   |
  sed -e '/^\s*$/d' -e 's/^\s*//'

1. Make the html file compliant by replacing the br-Tags
2. Get the wanted HTML-Element with xmlstarlet
3. suppress unwanted empty lines and leading whitespace in data / xmlstarlet output

cs_destroy

cs_destroy(3)							      cs/cs.h							     cs_destroy(3)

NAME

       cs_destroy  - clean up and dealloc a parse tree

SYNOPSIS

       #include <cs/cs.h>

       void cs_destroy (CSPARSE **parse);

ARGUMENTS

       parse - a pointer to a parse structure.

DESCRIPTION

       cs_destroy  will  clean	up all the memory associated with a CSPARSE structure, including strings passed to cs_parse_string.  This does not
       clean up any memory allocated by your own CSOUTFUNC or the HDF data structure passed to cs_init.  It is safe  to  call  this  with  a  NULL
       pointer, and it will leave parse NULL as well (ie, it can be called more than once on the same var)

RETURN VALUE

       parse - will be NULL
