That is not a even close to a clear specification.
We don't know what constitutes a variable name in the language you're trying to match.
We don't know if quotes can be escaped.
We don't know if quoted strings can extend beyond line boundaries.
Here is a clear specification of something that will match the examples you have provided:
Quote:
Match and print a string of the form:
where variable is a string of one or more alphabetic characters and string is a string of one or more alphabetic characters, zero or more non-single-quote characters on a single line surrounded by single-quote characters, or zero or more non-double-quote characters on a single line surrounded by double-quote characters.
With the above specification, the following seems to work with your sample input:

In a directory, there are two different file extensions (*.txt and *.xyz) having similar names of numerical strings (*).

I have a file name in $f. If $f has "-" at the beginning, or "=", or does not have extension ".ry" or ".xt" or ".dat" then cerr would not be empty.
Tried the following but having some problems.

Hi,
I have requirement to find the matching patterns of two files in Unix. One file is the log file and the other is the error list file. If any pattern in the log file matches the list of errors in the error list file, then I would need to find the counts of the match.
For example,

ao_string_tokenize
ao_string_tokenize(3) Programmer's Manual ao_string_tokenize(3)NAME
ao_string_tokenize - tokenize an input string
SYNOPSIS
#include <your-opts.h>
cc [...] -o outfile infile.c -lopts [...]
token_list_t* ao_string_tokenize(char const* string);
DESCRIPTION
This function will convert one input string into a list of strings. The list of strings is derived by separating the input based on white
space separation. However, if the input contains either single or double quote characters, then the text after that character up to a
matching quote will become the string in the list.
The returned pointer should be deallocated with free(3C) when are done using the data. The data are placed in a single block of allocated
memory. Do not deallocate individual token/strings.
The structure pointed to will contain at least these two fields:
tkn_ct The number of tokens found in the input string.
tok_list An array of tkn_ct + 1 pointers to substring tokens, with the last pointer set to NULL.
There are two types of quoted strings: single quoted (') and double quoted ("). Singly quoted strings are fairly raw in that escape char-
acters () are simply another character, except when preceding the following characters:
double backslashes reduce to one
' incorporates the single quote into the string
0fP suppresses both the backslash and newline character
Double quote strings are formed according to the rules of string constants in ANSI-C programs.
string string to be tokenized
RETURN VALUE
pointer to a structure that lists each token
ERRORS
NULL is returned and errno will be set to indicate the problem:
EINVAL - There was an unterminated quoted string.
ENOENT - The input string was empty.
ENOMEM - There is not enough memory. @end itemize
EXAMPLES
#include <stdlib.h>
int ix;
token_list_t* ptl = ao_string_tokenize(some_string)
for (ix = 0; ix < ptl->tkn_ct; ix++)
do_something_with_tkn(ptl->tkn_list[ix]);
free(ptl);
Note that everything is freed with the one call to free(3C).
