tokenizing on a string not a character

[gregIML]

Hi,

 

I'm trying to tokenize a text file or maybe an xml file depending on what is possible.

 

Ideally i'll have an xml with

 

<date>the date</date>

<title>the title</title>

<content>the content</content>

 

Is it possible to tokenize on the end tags of each field.  i.e </*>

 

so far i can only find ways to tokenize on individual characters using the strtok() function, not a string of characters.

 

any help would be greatly appreciated.

 

thanks in advance

Depending on what you're doing, an XML parser may be better. Something like this?

 

<pre>
<?php
$data = <<<DATA
	<date>the date</date>
	<title>the title</title>
	<content>the content</content>
DATA;
$pieces = preg_split('%</[^>]+>%', $data, -1, PREG_SPLIT_NO_EMPTY);
foreach ($pieces as &$piece) {
	$piece = htmlspecialchars($piece);
}
print_r($pieces);
?>
<pre>

That's really useful thank you.

 

I'm now getting the situation where it is printing the first tag (slightly overlooked that one) i need what's between the tags, how is this done?

 

Thanks in advance

<pre>
<?php
$data = <<<DATA
	<date>the date</date>
	<title>the title</title>
	<content>the content</content>
DATA;
preg_match_all('%<([^>]+)>(.*?)</\1>%', $data, $matches);
print_r($matches);
?>
<pre>

I'm still really struggling with this.

 

i have an xml file

<Date>30th January 2008</Date>
<Title>Hello</Title>
<Content>some content goes here</Content>

 

I want to output

 

30th January 2008

Hello

some content goes here

 

how can i do that?

 

so far this

 

 

<pre>
<?php
$data = <<<DATA
	<date>the date</date>
	<title>the title</title>
	<content>the content</content>
DATA;
preg_match_all('%<([^>]+)>(.*?)</\1>%', $data, $matches);
print_r($matches);
?>
<pre>

 

this outputs this

Array ( [0] => Array ( [0] => 30th January 2008  [1] => [2] => some content goes here  ) [1] => Array ( [0] => Date [1] => Title [2] => Content ) [2] => Array ( [0] => 30th January 2008 [1] => Hello [2] => some content goes here ) )

how do i just get the content and print it out.  If someone could just even direct me to the right php function i'll be able to do it, i really cant find this.

 

thanks

instead of print_r

use something like

$xmlvals=array_combine($matches[1],$matches[2]);

 

now u have a spanking new array with $key => $val equivalents

 

 

echo "Title: $xmlvars[title]<BR>";
echo "Date: $xmlvars[date]<BR>";

 

enjoy

Thank you laffin, that is great help.

 

I was using that xml as an example, let's say i didnt know what the xml tags were, i just want to print out what is between each tag in order, so i need to use the position in the new array not the name,  so i want to do something along the lines of

$xmlvars[0];

 

not

 

$xmlvars[title];

 

how would i do that?

OK unless you do have a solution for my question please dont worry.  I've realised that if the tags in the xml were numbers i can scroll through them no problem using a for loop.

 

Thanks for both of your help

u can keep them as they are

and using foreach to go thru the array

 

foreach($xmlvars as $key => $val)
   echo "$key: $val<br>";
