Title says all. How can I get the text between HTML nodes using PHP? Any ideas? Below is my HTML structure.
<html>
<head>
<title>Test Page</title>
</head>
<body>
<div id="outer">
<div id="first">
<p class="this">Hello</p>
<p class="this">Community</p>
</div>
<div id="second">
<p class="that">Stack</p>
<p class="that">Overflow</p>
</div>
</div>
</body>
Expected output:
HelloStackOverflowCommunity
That's quite easy, get PHP Simple HTML DOM Parser here: http://sourceforge.net/projects/simplehtmldom/files/
Then use the following code:
/* include simpledom*/
include('simple_html_dom.php');
/* load html string */
$html_string = <<<HTML
<html>
<head>
<title>Test Page</title>
</head>
<body>
<div id="outer">
<div id="first">
<p class="this">Hello</p>
<p class="this">Community</p>
</div>
<div id="second">
<p class="that">Stack</p>
<p class="that">Overflow</p>
</div>
</div>
</body>
</html>
HTML;
/* create simple dom object from html */
$html = str_get_html($html_string);
/* find all paragraph elements */
$paragraph = $html->find('div[id=outer] div p');
/* loop through all elements and get inner text */
foreach($paragraph as $p){
echo $p->innertext;
}

I would recommend you to use PHP inbuilt DOMDocument rather than a third party class like simplehtmldom.
On big HTML files they are really slow (I have worked with them).
<?php
$html ='
<html>
<head>
<title>Test Page</title>
</head>
<body>
<div id="outer">
<div id="first">
<p class="this">Hello</p>
<p class="this">Community</p>
</div>
<div id="second">
<p class="that">Stack</p>
<p class="that">Overflow</p>
</div>
</div>
</body>
';
// a new dom object
$dom = new domDocument;
$dom->preserveWhiteSpace = false;
// load the html into the object
$dom->loadHTML($html);
// get the body tag
$body = $dom->getElementsByTagName('body')->item(0);
// loop through all tags
foreach($body->getElementsByTagName('*') as $element ){
// print the textValue
print $element->firstChild->textContent;
}
The output would be HelloCommunity StackOverflow
Regular expressions are strongly not recommended to parse HTML.
Use Simple HTML library: http://sourceforge.net/projects/simplehtmldom/files/simplehtmldom/
Include it: include 'simple_html_dom.php';
Get tags you need: $tags = $html->find('p');
Create array: $a = array(); foreach ($tags as $tag) $a[] = $tag->innertext;;
Create your string: $string = $a[0] . $a[2] . $a[3] . $a[1];
You could try:
$text = strip_tags($html);
http://www.php.net/manual/en/function.strip-tags.php
That will get you quite far. It leaves spaces and returns, but those are easy to remove.
$clean = str_replace(array(' ',"\n","\r"),'',$text);
http://www.php.net/manual/en/function.str-replace.php
Using it on your example gives:
TestPageHelloCommunityStackOverflow
If you want to leave some spaces intact you could instead try:
$clean = trim(implode('',explode("\n",$text)));
which results in:
Test Page Hello Community Stack Overflow
Many variations are possible.
Try this one
function getTextBetweenTags($string, $tagname)
{
$pattern = "/<$tagname>(.*?)<\/$tagname>/";
preg_match($pattern, $string, $matches);
return $matches[1];
}
You have to loop through the $matches array...
