Shell Programming and Scripting

Hi experts,

As i am a novice unix player...so need help for the below query...banged my head from quite a while...

i have a set of html files, in which i need to search for string "Page"(case sensitive) and then replace the same with some numeric code ,say, "XXX1234".
Here in html files, there are some other similar strings like totalPage,currentPage,etc ....


i have tried using grap and using sed command, but problem here using grap is that it will return single line containing "Page" and then i can use sed to replace that word, but along with that i need non-replaced content as it is, and final output should be html file with only desired pattern replaced.

Was thinking , if any solution is there other than formal looping constructs.

would be a great help.....

please give a sample of input file and output expected
Waiting for more info, here is a piece of hazardous code ..

Code:

sed 's|\(.*[ </]\)Page\([ >].*\)|\1XXX1234\2|g' input >output

To be tryied ?

sed:

Code:

sed 's/\(^\|[^[:alnum:]_]\)Page\([^[:alnum:]_]\|$\)/\1XXX1234\2/g' infile

GNU sed:

Code:

sed 's/\bPage\b/XXX1234/g' infile
