Several interesting ideas floating around but I'd like to try one like this, jethro's being the closest to what I'd like to use. I realized my inital XML example was flawed, so let me try again with a more clear example. 
<DataStore>
    <DataRecord>
        <Data>123456</Data>
        <Data2>654321</Data2>
        <Data>123456</Data>
    </DataRecord>
    <DataRecord>
        <Data>123456</Data>
        <Data>123456</Data>
        <Data2>123456</Data2>
        <Data>1234/3456</Data>
        <Data>123456</Data>
        <Data>1234/3456</Data>
        <Data3>123456</Data3>
        <Data>123456</Data>
    </DataRecord>
    <DataRecord>
        <Data>123456</Data>
        <Data>123456</Data>
        <Data5>123456</Data5>
    </DataRecord>
</DataStore>

# From that I want it to loop through and store each <DataRecord> ... 
+</DataRecord>
# From then, if it matches on 4 digits followed by a forward slash I
# want it to output the whole <DataRecord> to screen, not just the mat
+ched lines from second filter.

# For that, I've tried this example

    open(FILE, "< $FILE") or die "ERROR: $!";

    while (<>) {
        if (/<DataRecord>/ ... /<\/DataRecord>/) {
            @cache=();
        }
        push(@cache, $_);
        
        if (m/<Data>\d{4}\//){
            print @cache;
        }
    }
    close (FILE);
    
# The output of that is

        <Data>1234/3456</Data>
        <Data>1234/3456</Data>
        
# where I would prefer to see

        <Data>123456</Data>
        <Data>123456</Data>
        <Data2>123456</Data2>
        <Data>1234/3456</Data>
        <Data>123456</Data>
        <Data>1234/3456</Data>
        <Data3>123456</Data3>
        <Data>123456</Data>

I wrote it several different ways, and either it prints every <DataRecord> or only filtered <Data> lines, neither is what I need. I want it to print the entire <DataRecord> if that record matches on the second pattern. Clearly I'm doing it wrong but I'm not seeing what, so I assume its glaringly obvious.
