请教：<table width=100 class='c' style='border:1' title="t" >要取得这里面所有的属性，属性位置不定，该正则该怎么写？

Question

width=str.replace(/(.*)(width=)['|"]?(\w*)['|"]?(\s)(.*)/,"$3");

Answer 1

width=100 class='c' style='border:1' title="t"我是想取得所有属性：
width
class
style
title

Answer 2

写到一起正则太长，分开写。
width=str.replace(/(.*)(width=)['|"]?(\w*)['|"]?(\s)(.*)/,"$3");
class=str.replace(/(.*)(class=)['|"]?(\w*)['|"]?(\s)(.*)/,"$3");
style=str.replace(/(.*)(style=)['|"]?(\w*)['|"]?(\s)(.*)/,"$3");
title=str.replace(/(.*)(title=)['|"]?(\w*)['|"]?(\s)(.*)/,"$3");

<SCRIPT>
function ShowAttribs(oElem)
{
    txtAttribs.innerHTML = '';    // Retrieve the collection of attributes for the specified object.
    var oAttribs = oElem.attributes;    // Iterate through the collection.
    for (var i = 0; i < oAttribs.length; i++)
    {
        var oAttrib = oAttribs[i];        // Print the name and value of the attribute. 
        // Additionally print whether or not the attribute was specified
        // in HTML or script.
        txtAttribs.innerHTML += oAttrib.nodeName + '=' + 
            oAttrib.nodeValue + ' (' + oAttrib.specified + ')<BR>';

Answer 4

$s = <<< TEXT
<table width=100 class='c' style='border:1' title="t" >
TEXT;
preg_match_all("/(\w+)=([\"']?)(.+)\\2[\s>]/sU", $s, $r);print_r($r);

Answer 5

针对下面的这种情况，能否改成能区别为不同递归层次的？<table width=100 class='c' style='border:1' title="t" >
<tr><td>
<table width=15 class='c22' style='border:1' title="标题" >
<tr><td>
</td>
</tr>
</table>
</td>
</tr>
</table>

Answer 6

<?php
$str = <<<EOT
<table width=100 class='c' style='border:1' title="t" >
EOT;
preg_match_all('|([a-z]+)=([\']?)(.+)\2[\s>]|iU', $str, $arr);
print_r($arr[1]);
?>output：Array
(
    [0] => width
    [1] => class
    [2] => style
    [3] => title
)

Answer 7

能不能得到这样的结果：
    [0] => Array
        (
            [0] => width=100 
            [1] => class='c' 
            [2] => style='border:1' 
            [3] => title="t" 
        ),
    [1] => Array
        (
            [4] => width=15 
            [5] => class='c22' 
            [6] => style='border:1' 
            [7] => title="标题" 
        )

Answer 8

<?php
$str = <<<EOT
<table width=100 class='c' style='border:1' title="t" >
EOT;
preg_match_all('|(([a-z]+)=([\']?)(.+)\3)[\s>]|iU', $str, $arr);
print_r($arr[1]);
?>output：Array
(
    [0] => width=100
    [1] => class='c'
    [2] => style='border:1'
    [3] => title="t"
)

Answer 9

谢谢，是针对本身就嵌套的内容：
$str = <<<EOT
<table width=100 class='c' style='border:1' title="t" >
<tr><td>
<table width=15 class='c22' style='border:1' title="标题" >
<tr><td>
</td>
</tr>
</table>
</td>
</tr>
</table>
EOT;
我想得到的结果是：
    [0] => Array
        (
            [0] => width=100 
            [1] => class='c' 
            [2] => style='border:1' 
            [3] => title="t" 
        ),
    [1] => Array
        (
            [4] => width=15 
            [5] => class='c22' 
            [6] => style='border:1' 
            [7] => title="标题" 
        )目前得到的结果是：
    [1] => Array
        (
            [0] => width=100
            [1] => class='c'
            [2] => style='border:1'
            [3] => title="t"
            [4] => width=15
            [5] => class='c22'
            [6] => style='border:1'
            [7] => title="标题"
        )

Answer 10

没有时间了，这个办法有点笨<?php
$str = <<<EOT
<table width=100 class='c' style='border:1' title="t" >
<tr><td>
<table width=15 class='c22' style='border:1' title="标题" >
<tr><td>
</td>
</tr>
</table>
</td>
</tr>
</table>
EOT;
preg_match_all('|<table[^>]+>|i', $str, $s);foreach ($s[0] as $v)
{
preg_match_all('|(([a-z]+)=([\']?)(.+)\3)[\s>]|iU', $v, $arr);
$r[] = $arr[1];
}
print_r($r);
?>output：
Array
(
    [0] => Array
        (
            [0] => width=100
            [1] => class='c'
            [2] => style='border:1'
            [3] => title="t"
        )    [1] => Array
        (
            [0] => width=15
            [1] => class='c22'
            [2] => style='border:1'
            [3] => title="标题"
        ))

Answer 11

错了，应该是
(?<=\s)([^\s]+?)

Answer 12

(?<=\s)([^\s]+?)
得到结果是：
Array
(
    [0] => Array
        (
            [0] => width=100
            [1] => class='c'
            [2] => style='border:1'
            [3] => title="t"
            [4] => >
            [5] => <tr><td>
            [6] => <table
            [7] => width=15
            [8] => class='c22'
            [9] => style='border:1'
            [10] => title="标题"
            [11] => >
            [12] => <tr><td>
            [13] => </td>
