Shell Programming and Scripting

Hi. I have to delete the content between all the occurrences of the xml tags in a single file.

For example:

* The tags <script>.....................</script> occurs more than once in the same file.

* It follows tagging rules meaning a start tag will be followed by an end tag. Will not have two continuous similar opening tags.

* But the tags are not necessarily in separate lines.

I used the below script which has deleted just the first occurrence in the file.

Code:

sed -e "s/ <script>*?<\/script>//g" $INF > $OUTF

Please help me in doing this. Since i have to process huge amount of data, more efficient method would be better.

If there is any other way apart from sed and awk that would also be better.

Something like this?

Code:

awk '/<script>/{p=1} /<\/script>/{p=0; next}!p' file

looks like it's deleting from the begining of the line where the <script> and </script> are located.

test.file

Code:

this is <script> the first line in the file1
and the second </script> line
and the third line in the file

when I execute the script
awk '/<script>/{p=1} /<\/script>/{p=0; next}!p' test.file
I get

Code:

and the third line in the file

I am assuming Mr satheeshkumar want is

Code:

this is  
line
and the third line in the file

Thanks.

Thanks Frank. It removes contents in all the occurrence of <script> and </script> tag. It removes the content in the complete line where the above tags are present.

Could you please help me to remove the content which are between those tags instead of removing everything in a line.

Example:

*Below is the output that i get when i execute your command

input file content:

client side<script>java script</script>java scripting is.......
server side<scipt>classic asp</script>ASP is a microsoft technology.......

satheesh here

output:

satheesh here

But i want the output as:

client side java scripting is.......
server side ASP is a microsoft technology.......

You are correct jville. Thats what i need exactly.

Try:

Code:

awk '
/<script>/ && /<\/script>/{
  sub("<script>.*</script>",x)
  if($0){print}
  next
}
/<script>/{p=1} /<\/script>/{
  p=0; next
}
!p' file

Frank it works fine for the first line. But when it comes to the next line of input it does the same error. It removes the complete line instead of just removing the content between the <script> </script> tag.

This time i get the output as

client side java scripting is.......

satheesh here

instead of

client side java scripting is.......
server side ASP is a microsoft technology.......
satheesh here

Second line of input has been deleted as the whole. It seems that the conditional deletion works only for first occurrence.

Thanks

Code:

awk '
/<script>/ && /<\/script>/{
  sub("<script>.*</script>",x)
  if($0){print}
  next
}
/<script>/{
  sub("<script>.*",x)
  if($0){print}
  p=1
} 
/<\/script>/{
  sub(".*</script>",x)
  if($0){print} 
  p=0
  next
}
$0 && !p' file
