如何使用php将标签的所有属性从字符串解析为数组？

Question

我有一个类似...的html字符串

<match id="18" srs="ICC Womens World Cup Qualifier, 2010" mchDesc="BANW vs PMGW" mnum="4th Match">

使用 php 我如何将这个字符串拆分/解码/解析为可访问对象（键值对），例如......

array(
    "id"=>"18", 
    "srs"=>"ICC Womens World Cup Qualifier, 2010", 
    "mchDesc"=>"BANW vs PMGW", 
    "mnum"=>"4th Match"
);

输出：

Array
(
    [id] => 18
    [srs] => ICC Womens World Cup Qualifier, 2010
    [mchDesc] => BANW vs PMGW
    [mnum] => 4th Match
)

Answer 1

使用DOMDocument 和DOMAttr：

$str = '<match id="18" srs="ICC Womens World Cup Qualifier, 2010" mchDesc="BANW vs PMGW" mnum="4th Match">';
$dom = new DOMDocument;
libxml_use_internal_errors(true);
$dom->loadHTML($str);

$result = [];

foreach($dom->getElementsByTagName('match')->item(0)->attributes as $attr) {
    $result[$attr->name] = $attr->value;
}

print_r($result);

主要优点是它不关心属性值是用单引号还是双引号括起来（或根本没有引号），等号前后是否有空格。

Answer 2

这应该可行。

(\w+)\=\"([a-zA-Z0-9 ,.\/&%?=]+)\"

代码 PHP：

<?php
$re = '/(\w+)\=\"([a-zA-Z0-9 ,.\/&%?=]+)\"/m';
$str = '<match id="18" srs="ICC Womens World Cup Qualifier, 2010" mchDesc="BANW vs PMGW" mnum="4th Match">
';

preg_match_all($re, $str, $matches);

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

print_r($c);

输出：

Array
(
    [id] => 18
    [srs] => ICC Womens World Cup Qualifier, 2017
    [mchDesc] => BANW vs PMGW
    [mnum] => 4th Match, Group B
    [type] => ODI
    [vcity] => Colombo
    [vcountry] => Sri Lanka
    [grnd] => Colombo Cricket Club Ground
    [inngCnt] => 0
    [datapath] => google.com/j2me/1.0/match/2017/
)
