ereg help

[Anon]

Ideally what I want to do is write an ereg_replace that changes all table tags to width=100% and cellpadding= 7.. I have no idea how to write a regular expression for this..

Any help.. Here is my existing code. Fairly simple and to the book.. Just need help with the ereg_replace

<?
$string = fopen("dmo0908.html", "r");

while (!feof($string)) {
$string2 = fgets($string,255);
$string3 = strip_tags($string2,"<table>,<tr><td></td></tr></i><b></b><p><br><h1></h1><i>");

$string3 = ereg_replace("<TABLE CELLSPACING=0 BORDER=0 CELLPADDING=7 WIDTH=648>", "<TABLE CELLSPACING=0 BORDER=0 CELLPADDING=7 WIDTH=100%>", $string3);

echo $string3,"\n";
}
fclose ($string);

?>

Why does know want to help me on this topic. I have been trying to figure out regular expressions for days without any luck. Can someone please help me out here.

What I am doing is opening an html doc reading for table tags and replacing those tags via this ereg

$string3 = ereg_replace("/(<)(table)(\s|\S|[a-zA-Z0-9])*(>)/", "<TABLE CELLSPACING=0 BORDER=0 CELLPADDING=7 WIDTH=80%>", $string2);

However I am having problems with the regular expression (regex). Please someone shed some light onthis.

Hi Ray!

the regular expression I would use for replacing only the '<table width=100%>' would be: '^<table width=100%>$'

for replacing something like '<table width=[any number at least of 1 digit and at most of 3, in % or px]>':

'^<table width=[0-9]{1,3}(%|px)>$'

I havent use ereg_replace, but i used ereg and i use it on this way: ereg('^<table width=[0-9]{1,3}(%|px| )>$',$miString)
(I think is the same way for ereg_replace)

Hope this helps.

Hi!!, I think I make a mistake in the interpetration of your problem, the expression I gave is for exactly the '<table width=100%>' string.

if you have a line like '... <table width=100%> ...' (where ... means anything)
you must use:

'<table width=100%>'

and for replacing something like '... <table width=[any number at least of 1 digit and at most of 3, in % or px]> ...':

'<table width=[0-9]{1,3}(%|px)>'
