Recursive functions work just fine in PHP. What's the error message?
As far as I can see, there's nothing wrong with what you've posted, except for
where there's some inefficiency due to not having found the right functions to
use (see corrections below).
here's the code snippet:
function parsehtmlline($line)

strlen(strstr($line, !--)) == 0) {
if (strpos($line, #include)===FALSE strpos($line, !--)===FALSE)

/* extract the filename */
$ssi = extractHTMLssi($line);

// for now just print the line.

$iss=strrev($ssi);
$strptr = strstr($iss, \);
$iss = substr($strptr, 1, -1);
$ssi = strrev($iss);
}
return $ssi;
I'd replace the whole of this function body with something like:
$pos = strpos($line, '');
if ($strpos===FALSE):
return $line;
else:
return substr($line, $pos+1, strrpos($line, '')-1);

Re: [PHP] html parsing
Hi Mike,
(I know it can probably be done better, or more elegant).
The problem is that the recursion doesn't seem to stop. (Unless there
are html ssi's that loop) there shouldn't be a problem. It basically
just freezes up (probably the recursion not terminating/ falling back.)
However the html just displays fine when I don't use recursion, so t
somewhat baffled me that when I use recursion the script doesn't
terminate. I did get to see some error msgs about problems with file
streams. Maybe it is running out of file handles ?
thanks,
Ron

Re: [PHP] html parsing
Yes I do have SSI enabled here is what I am doing. I have a php script that reads (a basic) file with html in it. (meaning it it would have an html/shtml extension it would just work in a browser. Now I rename the file to myhtml.dat and let the script read it and print it to stdout. That works like a char. until there's a server side include in the html page. (ssi's work in both html and in php) I tried to use ?php include(that.file); ? but that doesn't seem to work Tom Ray [Lists] wrote: Ron Croonenberg wrote: Hello, I have a script that ads data to a html template.

RE: [PHP] html parsing question
I've got a little question. I am writing a page where I would like to
parse my own invented HTML-looking tags (but want to keep the real
HTML
tags intact). I use a buffer for the output, and just before the end
use
ob_get_contents() to get the whole buffer which I want to check for
those tags.
(Something like:
$tag-content = ob_get_contents();
$output = $tag-interpret();
ob_end_clean();
echo $output;
)
Now my question is, what is the fastest way to search and replace
through this file, whereby the interpretation of the tag can be
somewhat
complicated?
I first just had a loop running character by character through this
text, looking for tags, but that is obviously way too slow.
Now I have something like:
preg_replace_callback (/(.+)/, array($this, 'tag_callback'),
$this-content);
But then I don't know how to interpret different tags differently. Any
suggestions?
(A tag looks like: CANTR REPLACE NAME=text where then the whole tag
has to be replaced by something called 'text' that has to be looked up
in a table. So, CANTR REPLACE NAME=text has to be replaced with
something else than CANTR REPLACE NAME=main - well, you get the
idea.)
Here's an example of how to use preg_replace_callback. Within the
callback() function, $matches[1] is going to contain whatever value was
in your NAME attribute of your CANTR tag. Act accordingly to it.
?php
$text = 'Hello cantr replace text=name. You are on page cantr
replace text=main right now.';
function callback($matches)
{
switch($matches[1])
{
case 'name':
$retval = 'John';
break;
case 'main':
$retval = 'Index.php';
break;
}
return $retval;
}
$new_text = preg_replace_callback('/cantr replace
text=([^]+)/i','callback',$text);
echo hr;
echo $new_text;
?
