Regular expression to scan html-tag

[Anon]

I´m trying to extract special self-defined tags out of a template-file.

A small example:

...
<loop name="hello world" from=2 to=3>
text between the tags
</loop>
...

What i need is a regular expression that gives bag a list of attributes within the tag (name="hello world" from=2 to=3) and
the text (text between the tags).

Thanks in advance Michael

hiya,

have you tried using the xml libraries? you might think it's an overkill, but it's quite straightforward to knock up a parser for what you mentioned.

the xml parser is event based so for each tag you're interested in, store the attributes. onced parsed you can look at the elements/attributes/contents of the document and do what you like with it...

have a look at http://www.phpbuilder.com/columns/justin20000428.php3 for a good article on this stuff

Well i yust tried this way but it is not really the thing i want.

The idea behind my question is a template engine that consists of some new tags and the "oldstyle" parameters from fasttemplate.

To find a the new tag i´ve found a regular expression that does everything needed:

preg_match_all("=<loop[^{>]>(.)</loop>=siU",$file,$a);}

Now i need one expression to extract all the different attributes in a tag.

When all this is done the programm replaces the new tag with the normal html.

Example:

<loop name="test" from=1 to=3>
<tr><td>{test_cell1}</td></tr>
</loop>

==>

<tr><td>Value 1</td></tr>
<tr><td>Value 2</td></tr>
<tr><td>Value 3</td></tr>

no i've got the answert....

here are two functions.
the first one works that way. as attriput ou put the html tag and you'll get an array with all the attribut plus the name of the tag.

the second function you can put a hole htmlsite. As answered you will get an array with all the tags in the format i told you befor....

i hope it will serve you and it would not make a lot of trubles. I can work with it..
here the code..
i would make it saver if you want to use it realy

function get_tagattribut($str){
$res = array();
$arr = array();
ereg('<[^ >]+', $str,$res['tag']);
$res['tag']=substr($res['tag'][0],1,strlen($res['tag'][0]));
while(ereg('[^ <>]+[ ]=[ ][^ ><]+',$str,$arr)){
$arr= $arr[0];
$arr=explode('=',$arr);
$str = ereg_replace($arr[0].'[ ]=[ ]'.$arr[1],' ',$str);
$arr[1]=ereg_replace('["\']','',$arr[1]);
$res[trim($arr[0])]=trim($arr[1]);
}
return $res;
}

function parsehtml($str){
$arr = array();
$i = 1;
$temp='';
while(ereg('<[^{<>]+>',$str,$temp)){}
$str = str_replace($temp[0],'',$str);
$temp= $temp[0];
$temp= get_tagattribut($temp);
if (isset($arr[$temp['tag']]))
{
$temp['tag']=$temp['tag'].$i;
$i++;
}
$arr[$temp['tag']]=$temp;
}
return $arr;

}

for testing her a debugger code.....

$test = '<loop name ="cool" atr1="value1" > <br> <jumbo type= elefant weight = "heavy">';
$res = parsehtml($ta);

foreach($r as $tag => $el)
{
foreach($el as $atr => $value )
{echo($tag.': '.$atr.'='.$value.'<br>');}
}
