Parser

viper21634

I am trying to parse out some text out of a html file, I have set up a html file with the following code

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body>
<b>this is a heading</b><br>
test body1<br>
<b>this is heading2</b><br>
test body2<br>
<b>this is heading3</b><br>
test body3<br>
</body>
</html>

what do I need to do to just grab the code that is in the and the and put that text into a array to display to the user???

notionlogic

Open the file and read it into an array (http://www.php.net/manual/en/ref.filesystem.php) then process that array using Regular Expressions (http://www.php.net/manual/en/ref.pcre.php)

Ok, I got the first draft to work, now I have a problem. I need to parse some very strange code, I will post a example:

<p class="MsoNormal"><span style="mso-bidi-font-size:12.0pt;font-family:Verdana;
color:white"><font size="4">Could be Saturday before some get power</font></span><span style="mso-spacerun: yes; mso-bidi-font-size: 12.0pt; color: white">&nbsp;
      </span><span style="font-size:11.0pt;font-family:Verdana;color:white">Ronni
      Chase </span><st1:date Year="2002" Day="13" Month="11">
      <span style="font-size:
 11.0pt;font-family:Verdana;color:white">11-13-02</span></st1:date>
      <span style="font-size:11.0pt;font-family:Verdana;color:white"><o:p>
      </o:p>
      </span></p>
      <p class="MsoNormal"><span style="color:white">&nbsp;</span><span style="font-size:13.5pt;color:white"><o:p>
      </o:p>
      </span></p>
      <p class="MsoNormal"><b style="mso-bidi-font-weight:normal"><span style="font-size:12.0pt;color:white">About
      850 people were still without power Wednesday morning here in </span></b><st1:place>
      <st1:PlaceName>
      <b style="mso-bidi-font-weight:normal"><span style="font-size:12.0pt;color:white">Cumberland</span></b></st1:PlaceName>
      <b style="mso-bidi-font-weight:normal"><span style="font-size:12.0pt;color:white">
      </span></b><st1:PlaceType>
      <b style="mso-bidi-font-weight:normal"><span style="font-size:12.0pt;color:white">County</span></b></st1:PlaceType>
      </st1:place>
      <span style="font-size:12.0pt;color:white"><b style="mso-bidi-font-weight:normal">.<span style="mso-spacerun:yes">&nbsp;
      </span>Bobby Randolph, Volunteer Energy Manager for the Crossville Area

now I only want to code that is formated like this:

"><font size="4">Could be Saturday before some get power</font>

Now here is the code that I am using to parse it off

<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body>
<?php
$text = array();
$newtext = array();
$word = "";
$page = "http://localhost/news.html";
$fp = fopen( $page, "r" ) or die("couldn't open $page");
while ( ! feof( $fp ))
	$text[] = fgets( $fp, 1024 );
reset($text);
foreach($text as $key => $value)
{
if (preg_match ("/<P class=MsoNormal>.*?<FONT size=4>/i", $value))
	{
	$word = strip_tags($value);
	ereg_replace("<P class=MsoNormal><SPAN style='COLOR: white; FONT-FAMILY: Verdana'><FONT size=4>", " ", $value);
	$word = ereg_replace("</FONT></SPAN>", " ", $word);
	$newtext[] = $word;
	print strip$word;
	}
else
	{
	unset($text[$key]);
	}
}
?>

now that takes it off and puts it into a news ticker and links back to the news page. Well it wont parse the info off that I want. What am I doing wrong???😕

viper21634

any ideas??

Hi,

well at least one of your ereg_replace() statement
is not correct :

ereg_replace("", " ", $value)

ereg_replace send you back the modified value
so you need :

$string = ereg_replace($pattern,$replacement,$string)

Also the line :

print strip$word;

is suspect 🙂 (may be "print strip($word);" ? )

Actually, that print strip$word, well that was a little code I was using to try to see where the problem is, it is supposed to be print strip_tags($word); I thought that I took all of it out guess not :o

What do you think about taking the first array that I build with the raw page, running through it with a foreach() loop, and explode it down to the words into a second array, then run through that one and search it for a when I find that stik the text that follows it into a 3rd array and then use that one to make my output?? would that work?? or would it be a waste of time to code??
