Hi all.

Thank you for your assistance. As requested by one of the replies, here is some of the code 

    s/  <datafield tag="/./i;        #begin tag num with "."
    s/" ind1="/. /i;            #end tag num with ".  "
    s/" ind2="//i;                #remove text between indic
    s/">\n//i;                #to imprecise?  No, its OK.
    s/    <subfield code="/|/i;        #remove text between fields
    s/">//i;                #to imprecise?  No, its OK.
    s/<\/subfield>\n//i;            #remove text between fields
    s/<\/record>\n//i;            #remove record end marker
    s/<\/datafield>//i;            #remove end of field marker
    s/http:\/\/wc.slims.gov.za/WCPLIS/i;    #change SITA url to org
    s/<\/collection>\n//i;            #remove end of document
    if (/\d-\d/) {s/-//g};            #Remove hyphens in ISBN's

This part takes the xml code and puts it into the flat format as required. Below is a sample of the xml code

  <datafield ind1="1" ind2="4" tag="245">
    <subfield code="a">The solar system</subfield>
    <subfield code="c">Chris Oxlade [Author]</subfield>
  </datafield>

[download]

Below is the output of one line in the flat file. 

 .245. 14|aThe solar system|cChris Oxlade [Author]

This perl code is user for all lines with various MARC tags (.024.). It might be possible that I am putting the part to focus on the ISBN correction in the wrong place in the code. I used the line below: 

    if (/^.024. 3#|a/) {s/.{10}(.............)........../.020.  3#|a$1
+/};

I will try some of the suggestions and see if I can get it sorted. Thank you once again for assisting.
