The task seems easy: delete the section between "Answer:" and "NO."
Doable with sed by means of the N command and a loop. But sed has a portability issue regarding N on the last line.
So awk is the first choice here. del==0 is true if del is not initialized. A true without action defaults to {print}.

pmspeclocalpmda
PMSPECLOCALPMDA(3) Library Functions Manual PMSPECLOCALPMDA(3)NAME
__pmSpecLocalPMDA - process command-line argument for the table of DSO PMDAs
C SYNOPSIS
#include <pcp/pmapi.h>
#include <pcp/impl.h>
char *__pmSpecLocalPMDA(const char *spec);
cc ... -lpcp
DESCRIPTION
PCP contexts of type PM_CONTEXT_LOCAL are used by clients that wish to fetch metrics directly from one or more PMDAs on the local host
without involving pmcd(1).
__pmSpecLocalPMDA provides a convenience wrapper to be used by applications that wish to use a command line argument (usually with -K) to
control the DSO PMDAs that are available for a PM_CONTEXT_LOCAL context.
The spec argument specifies actions for one or more DSO PMDAs using up to four fields separated by commas (``,''), namely:
- an opcode with one of the values add (add a new entry), del (delete an existing entry) or clear (clear all entries from the table).
- the PMDA's domain number
- the path to the PMDA DSO (may be absolute or relative to the $PCP_VAR_DIR/pmdas directory and the DSO suffix is optional), and
- the name of the PMDA's initialization routine.
All fields are required to add a new entry. To delete an entry the opcode is required plus either or both of the domain number and path
fields. To clear all entries, only the opcode is required.
If spec is parsed successfully, then __pmLocalPMDA(3) is called with the extracted arguments.
RETURN VALUE
On success, __pmSpecLocalPMDA will return NULL.
On error or failure, __pmSpecLocalPMDA will return a pointer to a static error message.
EXAMPLES
Some examples of valid spec strings:
clear Delete all entries from the DSO table.
add,123,foo/foo_pmda,foo_init
Add the ``foo'' PMDA using domain 123. The PMDA's DSO is most likely in below the directory $PCP_PMDAS_DIR and named
foo/foo_pmda.so (for ELF-style platforms) or foo/foo_pmda.dylib (for BSD-style platforms) or fooo_pmda.dll (for Windows-style plat-
forms). The initialization routine for the ``foo'' PMDA is foo_init().
del,123
Delete the entry for the DSO with domain 123.
del,,foo/foo_pmda
Delete the entry with a pathname to the DSO that matches foo/foo_pmda.
del,123,foo/foo_pmda
Delete the entry for the DSO with either domain 123 and/or a pathname to the DSO that matches foo/foo_pmda.
