strip javascript and put back

MrBodean

I found this example
$maintext = preg_replace("'<script[^{>]?>.?<\/script>'si",} "", $maintext);

This strips out the javascript just fine, but what I need is to save those that are stripped out into some type of buffer so I can put them back in later.

I have tried the
"'<script[^{>]?>.?<\/script>'si"}
using eregi but does not seem to work. I need to pull them out, do a routine, then put them back in.

Any help would be appreciated...

Just save your original text in another variable...

$original_maintext = $maintext;
$maintext = preg_replace("'<script[^{>]?>.?<\/script>'si",} "", $maintext);

MrBodean

No that is not what I need, that does not tell me what text was replaced it only gives me a full copy of the original.

Here is an example

$maintext = "<script>this is a sample</script>other odd text<script>more text to remove and replace</script>";

I need to be able to pull out
"this is a sample" and
"more text to remove and replace"

put those into variables, then replace then with say "##item1##" and "##item2##"

then do another routine, then come back and replace the
"##item1##" with the "this is a sample" variable.

Hope that helps explain what I need...

How about instead of doing preg_replace you do preg_match, then str_replace with the match returned. (Or preg_replace if you don't trust str_replace for this.)

MrBodean

Well I tried the preg_match but it did not return anything. Would I use the same syntax for the pattern?

works---
$maintext=preg_replace("'<script[^{>]?>.?</script>'si",} "",$maintext);

does not pass back anything
preg_match("'<script[^{>]?>.?</script>'si",} $maintext,$matches);

mtmosier

Yes, the same expression should work.

<?php

$maintext = "<script>this is a sample</script>other odd text<script>more text to remove and replace</script>"; 

preg_match("'<script[^>]*?>.*?</script>'si", $maintext,$matches);
print_r($matches);

/*
Outputs:

Array
(
    [0] => <script>this is a sample</script>
)
*/
?>

MrBodean

well I copied your code (which was what I had tried before) and this is what it outputs:

Array ( [0] => )

scratches head ummm... hmmm... well.

What OS and version? I tried with 4.2.2, 4.3.10, 5.0.3 on linux.

Maybe change the 's you use as delimiters to something a bit more typical, like # or / (escaping /s in the expression if the latter). Since it works with preg_replace I can't imagine that being the problem, but...

You copy and pasted, right? No chance of a typo or other mistake? Just checking.

running latest on unix

I ended up trying this and it worked...
preg_match_all("'<script[^{>]?>(.?)</script>'si",} $maintext,$matches);

foreach( $matches[1] as $link)

echo $link;

Thanks for the help, hey if you get a chance look at my other questions here, about eregi 🙂

Trying to combine two routines and can't figure a way to make the expression work...

Thanks again
