Need help pulling remote contents

[kevin87]

Hi everyone,

 

I need some help pulling data from a remote site.  Currently I am using the following code which works and pulls all of the data. The next step is where I am a little lost.

$str = file_get_contents("http://www.airnav.com/airport/KARR");

I would like to only pull the following data from the remote site.

<A name="ops"></A><H3>Airport Operations</H3>
<TABLE cellpadding=0 cellspacing=0 border=0>
<TR><TD nowrap valign=top align=right>Airport use: </TD><TD valign=top>Open to the public</TD></TR>
<TR><TD nowrap align=right>Activation date: </TD><TD>04/1966</TD></TR>
<TR><TD nowrap valign=top align=right>Sectional chart: </TD><TD valign=top><A href="/sectionals">CHICAGO</A></TD></TR>
<TR><TD nowrap align=right>Control tower: </TD><TD>yes</TD></TR>

Can anyone help me out with this?

 

Thanks,

Kevin

Find what you are looking for using regex

$html = file_get_contents("http://www.airnav.com/airport/KARR");
preg_match('~<a name="ops"></a>.+</h3>(.*?)</table>~is', $html, $matches);
$targetData = trim($matches[1]);

echo $targetData;

If you dont want the html included then apply strip_tags to $targetData;

Thanks a lot for the response. I ran this code and had a little trouble, but I think it is getting closer. Maybe I can understand it if there is less data. What if I just wanted to grab this string and print it?

 

<A name="ops"></A><H3>Airport Operations</H3>

Also a second question. Is there a way to print only line 75 to 100 when using 

$html = file_get_contents("http://www.airnav.com/airport/KARR");

Thanks,

I have issue with my regex pattern, change it to

preg_match('~<a name="ops"></a>(.*?)</table>~is', $html, $matches);

$targetDate will contain

<H3>Airport Operations</H3>
<TABLE cellpadding=0 cellspacing=0 border=0>
<TR><TD nowrap valign=top align=right>Airport use: </TD><TD valign=top>Open to the public</TD></TR>
<TR><TD nowrap align=right>Activation date: </TD><TD>04/1966</TD></TR>
<TR><TD nowrap valign=top align=right>Sectional chart: </TD><TD valign=top><A href="/sectionals">CHICAGO</A></TD></TR>
<TR><TD nowrap align=right>Control tower: </TD><TD>yes</TD></TR>
<TR><TD valign=top align=right>ARTCC: </TD><TD valign=top>CHICAGO CENTER</TD></TR>
<TR><TD valign=top align=right>FSS: </TD><TD valign=top>KANKAKEE FLIGHT SERVICE STATION</TD></TR>

Also a second question. Is there a way to print only line 75 to 100 when using 

If you want specific lines, then you could do

$html = file("airport.html");

$targetData ='';
// start at line 75 and loop till line 100
for($i = 74; $i <= 99; $i++)
{
	$targetData .= $html[$i]; // add html to variable
}

echo $targetData; // echo html
