README

This package is based on querypath/querypath, and arthurkushman/query-path

This package is licensed under an MIT license (COPYING-MIT.txt).

At A Glance

QueryPath is a jQuery-like library for working with XML and HTML documents in PHP. It now contains support for HTML5 via the HTML5-PHP project.

Why this lib was forked and recoded

Incompatible with php 8.1

Installation

composer require satisfactory-clips-archive/querypath

Gettings Started

Assuming you have successfully installed QueryPath via Composer, you can parse documents like this:

// HTML5 (new)
$qp = html5qp("path/to/file.html");

// Legacy HTML via libxml
$qp = htmlqp("path/to/file.html");

// XML or XHTML
$qp = qp("path/to/file.html");

// All of the above can take string markup instead of a file name:
$qp = qp("<?xml version='1.0'?><hello><world/></hello>")

But the real power comes from chaining. Check out the example below.

Example Usage

Say we have a document like this:

<?xml version="1.0"?>
<table>
  <tr id="row1">
    <td>one</td><td>two</td><td>three</td>
  </tr>
  <tr id="row2">
    <td>four</td><td>five</td><td>six</td>
  </tr>
</table>

And say that the above is stored in the variable $xml. Now we can use QueryPath like this:

<?php
// Add the attribute "foo=bar" to every "td" element.
qp($xml, 'td')->attr('foo', 'bar');

// Print the contents of the third TD in the second row:
echo qp($xml, '#row2>td:nth(3)')->text();

// Append another row to the XML and then write the
// result to standard output:
qp($xml, 'tr:last')->after('<tr><td/><td/><td/></tr>')->writeXML();

?>

(This example is in examples/at-a-glance.php.)

With over 60 functions and robust support for chaining, you can accomplish sophisticated XML and HTML processing using QueryPath.

From there, the main functions you will want to use are qp() (alias of QueryPath::with()) and htmlqp() (alias of QueryPath::withHTML()).

QueryPath Format Extension

format()

\QueryPath\DOMQuery format(callable $callback [, mixed $args [, $... ]])

To add QueryPath as a library in your project, run composer require satisfactory-clips-archive/querypath

<?php
QueryPath::enable(Format::class);
$qp = qp('<?xml version="1.0"?><root><div>_apple_</div><div>_orange_</div></root>');

$qp->find('div')
        ->format('strtoupper')
        ->format('trim', '_')
        ->format(function ($text) {
            return '*' . $text . '*';
        });

$qp->writeXML();

OUTPUT:

<?xml version="1.0"?>
<root>
  <div>*APPLE*</div>
  <div>*ORANGE*</div>
</root>

formatAttr()

\QueryPath\DOMQuery formatAttr(string $name, callable $callback [, mixed $args [, $... ]])

A quick example:

<?php
QueryPath::enable(Format::class);
$qp = qp('<?xml version="1.0"?><root>' .
        '<item label="_apple_" total="12,345,678" />' .
        '<item label="_orange_" total="987,654,321" />' .
        '</root>');

$qp->find('item')
        ->formatAttr('label', 'trim', '_')
        ->formatAttr('total', 'str_replace[2]', ',', '');

$qp->find('item')->formatAttr('label', function ($value) {
    return ucfirst(strtolower($value));
});

$qp->writeXML();
