Data between strings...

tarqwin

I have a page full of news stories from a news based
company.

This page has heading, body and date etc, all layed out thus...

<story>
<date> 1-1-01 </date>
<header>Title</header>
<main>Story....</main>
</story>
etc...

And each story is contained within a <story> tag
(see http://www.stntreasury.com/idea.php4 and view source, I have hidden
the text, cause I wanna duplicate only the headers.
You'll see)

There are many stories on the page, and I need to use php to pick up all
the headers on a page, and then just display them, as links, and that
would
direct the user to a new page, with the story in full.

While I am comfortable with the logical side of how I am gonna do this, I
cannot find in my PHP books the command to pick up specific strings.
And how do I identify on the story page, what <header> tag applies to
what
<date> tag or <story> tag.
You with me?
Can anyone help me out?

I don't want the whole solution, as I wanna figure this out for my self,
but I just need a leg up so to speak...

If your using a database thats easy...

Simply grab all the headers from a table, and display them in a loop with something like

Where $newsid is the id of each piece of news and $newstitle is the title

Then run a query at the top of newsarchieves.php

if ($id) {
//select statement with WHERE newsid='$id'
//output
}

Something like that should work, if I read what you wanted correctly that is.

Not quite,
I am recieving a text file from a news company. THat text file has several <headline> tags, and serveral <summary> tags too.

I need to get all teh info from between these tags, and put them onto a page, as php variables.

I can put the text file on a page, and asign it as a variable itself, but I need to know how to pick out the many headline tags etc...

ANy other ideas?

Hi there,
A few days ago, I posted a question about detecting substrings, well that is sorted to a point...

I have this code...

<?
function inString($start, $end, $string)
{
eregi(".".$start."(.)".$end.".*",$string,$result);
return($result[1]);
}

$headline=inString("<headline>","</headline>",$idea);
$datetime=inString("<datetime>","</datetime>",$idea);
$summary=inString("<summary>","</summary>",$idea);
echo($headline);
echo($datetime);
echo($summary);
?>

this detects the tag <headline> and the close tag, and shows the text within the tags.

No probs, but when I have several tags (several stories) only the last story is shown.
Can anyone help me to ensure that the search for <headline> tags displays all the instances of <headline>

A reminder, all stories are enclosed within a <story> tag too.

How can I get round this?
Any ideas?

actually it looks like what you've got there is yr standard xml doc. it may be worth while to investigate that route...

the run down of xml/php is here:
http://www.php.net/manual/en/ref.xml.php

some site who's name i forget ran this tutorial:
http://www.phpbuilder.com/columns/jesus20000402.php3

then there's the "competition's" tutorial:
http://www.devshed.com/Client_Side/XML/XMLwithPHP1/

there's a pretty good intro to xml here:
http://www.w3schools.com/xml/default.asp

although i'm far from a pro at xml, it's a nifty way to store data in a platform and software-independent manner. the php tools for xml are a tad cryptic, but if you can build a regex you can figgure it out.
