Help in grep function or similar using awk
I have a list of id;
for example: file 1
dfghd
dfghe
dfgey
dfgeu
I have another data file that contain this ids as headers;
for ex. file2
>dfghd
gfdgfddl;klfkld;ld;lgl;dld'l'dv
>dfghe
gkwhjhsgdjdjdjhjddj
>dfgey
jdkjfhdjhfdkjhfdkhkdk
I wanted to compare file 1 and file 2 such a way that the output list the ids that are present in file 1 but not present in file 2.
For ex. the id 'dfgeu' is present in file 1 but its absent in file 2.
I want to have this id (dfgeu)which is missing in file 2 as header to be outputed.
Is there a way in awk to do this comparison of 2 files?
Please let me know.

html::tableparser::table
HTML::TableParser::Table(3pm) User Contributed Perl Documentation HTML::TableParser::Table(3pm)
NAME
HTML::TableParser::Table - support class for HTML::TableParser
DESCRIPTION
This class is used to keep track of information related to a table and to create the information passed back to the user callbacks. It is
in charge of marshalling the massaged header and row data to the user callbacks.
An instance is created when the controlling TableParser class finds a "<table" tag. The object is given an id based upon which table it is
to work on. Its methods are invoked from the TableParser callbacks when they run across an appropriate tag ("tr", "th", "td"). The object
is destroyed when the matching "/table" tag is found.
Since tables may be nested, multiple HTML::TableParser::Table objects may exist simultaneously. HTML::TableParser uses two pieces of
information held by this class -- ids and process. The first is an array of table ids, one element per level of table nesting. The second
is a flag indicating whether this table is being processed (i.e. it matches a requested table) or being ignored. Since HTML::TableParser
uses the ids information from an existing table to initialize a new table, it first creates an empty sentinel (place holder) table (by
calling the HTML::TableParser::Table constructor with no arguments).
The class handles missing "/tr", "/td", and "/th" tags. As such (especially when handling multi-row headers) user callbacks may be
slightly delayed (and data cached). It also handles rows with overlapping columns
