I have a slight problem and do not know where to start.
I have a text file that contains the following information.
MINI COOPER 2007, 30,000 miles, British Racing Green, full service history, metallic paint, alloys. Great condition. £5,995 ono Telephone xxxxx xxxxx
I need to populate the above information in the following format
<advert>
<manufacturer></manufacturer>
<make></make>
<model></make>
<price></price>
<miles></miles>
<image></image>
<desc><![CDATA[desc>
<expiry></expiry> // Any point in the future
<url></url> // Optional
</advert>
<advert>
The output should be.
</advert>
<advert>
<manufacturer>MINI</manufacturer>
<make></make>
<model></make>
<price>5,995</price>
<miles>30000</miles>
<image></image>
<desc><![CDATA[2007, British Racing Green, full service history, metallic paint, alloys. Great condition.Telephone xxxxxx xxxxxx]]></desc>
<expiry>Todays date 13/05/2013</expiry>
<url></url>
</advert>
Any help will be create appreciated.

Since sometimes commas are part of a field and sometimes they aren't you can't use commas or anything else as a field separator so you need something like this in GNU awk (for gensub() and strftime()):
gawk '{
print "<advert>"
printf "\t<manufacturer>%s</manufacturer>\n", $1
printf "\t<make></make>\n"
printf "\t<model></model>\n"
printf "\t<price>%s</price>\n", gensub(/.*£([[:digit:],]+).*/,"\\1","")
printf "\t<miles>%s</miles>\n", gensub(/.*[[:space:]]([[:digit:],]+)[[:space:]]+miles.*/,"\\1","")
printf "\t<image></image>\n"
printf "\t<desc><![CDATA[%s]]></desc>\n", gensub(/.*[[:space:]]+miles[[:space:]]*,[[:space:]]*(.*)/,"\\1","")
printf "\t<expiry>Todays date %s</expiry>\n", strftime("%d/%m/%Y")
printf "\t<url></url>\n"
print "</advert>"
}' file
My editor seems to choke on British pound signs so here's the above script running using a # symbol instead:
$ cat file
MINI COOPER 2007, 30,000 miles, British Racing Green, full service history, metallic paint, alloys. Great condition. #5,995 ono Telephone xxxxx xxxxx
$ gawk '{
print "<advert>"
printf "\t<manufacturer>%s</manufacturer>\n", $1
printf "\t<make></make>\n"
printf "\t<model></model>\n"
printf "\t<price>%s</price>\n", gensub(/.*#([[:digit:],]+).*/,"\\1","")
printf "\t<miles>%s</miles>\n", gensub(/.*[[:space:]]([[:digit:],]+)[[:space:]]+miles.*/,"\\1","
")
printf "\t<image></image>\n"
printf "\t<desc><![CDATA[%s]]></desc>\n", gensub(/.*[[:space:]]+miles[[:space:]]*,[[:space:]]*(.
*)/,"\\1","")
printf "\t<expiry>Todays date %s</expiry>\n", strftime("%d/%m/%Y")
printf "\t<url></url>\n"
print "</advert>"
}' file
<advert>
<manufacturer>MINI</manufacturer>
<make></make>
<model></model>
<price>5,995</price>
<miles>30,000</miles>
<image></image>
<desc><![CDATA[British Racing Green, full service history, metallic paint, alloys. Great con
dition. #5,995 ono Telephone xxxxx xxxxx]]></desc>
<expiry>Todays date 13/05/2013</expiry>
<url></url>
</advert>

Answer 2

Here's some example code that should get you going at least. Run like:
awk -f script.awk file.txt
Contents of script.awk:
{
for (i=1;i<=NF;i++) {
if ($i == "miles,") {
miles = $(i - 1)
$i = $(i - 1) = ""
}
if ($i ~ /£/) {
price = substr($i, 2)
$i = $(i + 1) = ""
}
}
gsub(/ +/, " ");
print "<advert>"
print "\t<manufacturer>" $1 "</manufacturer>"
print "\t<make></make>"
print "\t<model></make>"
print "\t<price>" price "</price>"
print "\t<miles>" miles "</miles>"
print "\t<image></image>"
print "\t<desc><![CDATA[" $0 "]></desc>"
print "\t<expiry>" strftime( "%d/%m/%Y" ) "</expiry>"
print "\t<url></url>"
print "</advert>"
}
Results:
<advert>
<manufacturer>MINI</manufacturer>
<make></make>
<model></make>
<price>5,995</price>
<miles>30,000</miles>
<image></image>
<desc><![CDATA[MINI COOPER 2007, British Racing Green, full service history, metallic paint, alloys. Great condition. Telephone xxxxx xxxx]></desc>
<expiry>13/05/2013</expiry>
