grep considers no logic but patterns when matching lines. It doesn't remember anything about previous lines and has no expression to carry information from previous lines across to next ones. The awk language is much better suited, since it deals with lines/patterns and has variables plus logical expressions. (I think sed does too in a fashion, but its expression syntax is rather convoluted. awk gives you straightforward variables with names, and straightforward expressions with if/else.) I'm only asking you for your data. I'm not even the first one.
If you really want I'll give you a ridiculous solution like grep pattern file | tail -n +5 | head -n 1 to get match 4 which is of course a very silly solution and might not work in Solaris. A less silly solution would be nawk '/pattern/ {} NR=2' but you asked for grep, this may not suit your needs, and there may be even more efficient ways to deal with the data depending on what it actually is and what you're trying to do.
You slur...I slur back....that is how that first part went......anyways...
See....you did not need data to answer and there was no problem adding on the excellent commentary/lead about awk. I know a lot of people often ask for the answer to their specific issue and want YOU the other poster to do all the work for them (sometimes very practical). I am still at the general question looking to get more of a clue phase but if you want to do all my work for me let me know...I am certain you can do it fast.
I have something to work with and can make some progress (fingers crossed).
Thank you so much: )

had to change the line for Solaris:
grep pattern file | tail +5 | head -1
I am not working with large files here and performance is not an issue......
The line is easy to use and works in the Bash shell so....why is this a silly solution, performance, crossplatform issues?
thanks again.

soap::deserializer
SOAP::Deserializer(3pm) User Contributed Perl Documentation SOAP::Deserializer(3pm)
NAME
SOAP::Deserializer - the means by which the toolkit manages the conversion of XML into an object manageable by a developer
DESCRIPTION
SOAP::Deserializer provides the means by which incoming XML is decoded into a Perl data structure.
METHODS
context
This provides access to the calling context of "SOAP::Deserializer". In a client side context the often means a reference to an
instance of SOAP::Lite. In a server side context this means a reference to a SOAP::Server instance.
EXAMPLES
DESERIALIZING RAW XML INTO A SOAP::SOM OBJECT
A useful utility for SOAP::Deserializer is for parsing raw XML documents or fragments into a SOAP::SOM object. SOAP::Lite developers use
this technique to write unit tests for the SOAP::Lite module itself. It is a lot more efficient for testing aspects of the toolkit than
generating client calls over the network. This is a perfect way for developers to write unit tests for their custom data types for example.
Here is an example of how raw XML content can be parsed into a SOAP::SOM object by using SOAP::Deserializer:
$xml = <<END_XML;
<foo>
<person>
<foo>123</foo>
<foo>456</foo>
</person>
<person>
<foo>789</foo>
<foo>012</foo>
</person>
</foo>
END_XML
my $som = SOAP::Deserializer->deserialize($xml);
