I am new to Perl and am trying to parse a message file and extract the data from the file that meet the criteria.
So what I am looking for are certain types of messages that are logged in a file.
Example: I only want to pull out the data(values) when it find the following strings:
id=
lo=
to=

Second part: How can pull out the data above that falls between each open and close <dsk1 ......... />


<dsk1 ldx="0" id="Apple_123" lo="90664930" to="50290243" rb="5601167285" wb="3166360469" re="207363559" we="141193363" rq="207492604" wq="152730850"
ure="207363559058" uwe="141193363182" urq="207492604103" uwq="152730850622"
pre="889919" pwe="878073" pro="889921" pwo="1100425" />
<dsk1 ldx="1" id="sun123" lo="91608370" to="51126057" rb="5666375308" wb="3212140435" re="209308380" we="135528403" rq="209434385" wq="147030757"
