Hello Urke,
Historians believe that Wed, 27 Jun 2001 at 22:25 GMT +0200 was when,
Urke [U] typed the following:
JA>> %SETPATTREGEXP="(?im)^(X\-Mailer)\:\s(.*?)$"%-
JA>> %REGEXPBLINDMATCH="%HEADERS
JA>> X-Mailer: N/A"%-
JA>> %SUBPATTERN="2"
U> Hmmm, is there some typo errors?
I don't think so. Is it not working for you? If not, what results
are you getting?

Ok, let me try to clarify. When you want search the headers, you use
%REGEXPBLINDMATCH="%HEADERS"
Now, what happens is, the macro %HEADERS is evaluated, ie the headers
are pasted in. You're making a mini-template inside the
%REGEXPBLINDMATCH macro. For this purpose, the template we want
would look like this:
<mini-template>
%HEADERS
X-Mailer: N/A
</mini-template>
The reason we want this particular template is because it will be
expanded to give something like:
<example>

In this example, there are two X-mailer lines. The regexp above will
only find the first one. But suppose you had a message with no
X-mailer field. The template gives you:

See how in this example, we only have one X-Mailer field? And this
one is the default value, "N/A". Now we don't have to worry about
an %IF statement, nor do we have to worry about a complicated regexp.
It's all taken care of automatically.
