Hướng dẫn php get tag content

Is it possible to get all HTML elements [children] with content using PHP [DOMDocument class]? I just can't get the results. Let say I only know that I will have tag but don't know what tags would be inside Example:

$doc = new DOMDocument[]; 
$el = "test1
Test2
";
$doc->loadHTML[$el];
$doc->getElementsByTagName["td"]->item[0]->nodeValue /* I only get plain text */

EDIT: No JavaScript like solution

This will give you all element information:

$html = "test1
Test2
";
$dom = new DOMDocument[];
$dom->loadHTML[$html];
foreach[$dom->getElementsByTagName['*'] as $element ]{
    echo "
";
    print_R[$element];
    echo "
";
}

To get Attribute information use like:

$p = $dom->getElementsByTagName['a']->item[0];
if [$p->hasAttributes[]] {
  foreach [$p->attributes as $attr] {
    $name = $attr->nodeName;
    $value = $attr->nodeValue;
    echo "Attribute '$name' :: '$value'
";
  }
}

If you want your file to be interpreted as php then your file must start and end with and everything outside of that is ignored by the php parser.


hellow..//normal test but ignred by php parser

Three types of tag are available in php
1.normal tag[]
2.short echo tag[]
3.short tag[]

short tag are bydefault available but can be disabled by short_open_tag = Off and also disabled bydefault if php will  built with --disabe--short--tags[]

As short tag can be disabled so only use the normal and short echo tag.

If your file only have php code then  do not use closing tag.




If you want to just print single text or something ,you should use shorthand version .

But if you want to process something, you should use normal tag.


If you embedded php with html and single line, do not need to use semicolon







but if you have multiple line, then use semicolon.
