php html dom解析器中的内联样式设置问题

嗨，我正在一个天气网站上做一个屏幕截图，该网站的div中有内联样式，没有类或id。下面是他们的代码：

<div class="TodaysForecastContainer">

                    <div class="TodaysForecastContainerInner">
                        <div style="font-size:12px;"><u>This morning</u></div>
                        <div style="position:absolute;top:17px;left:3px;">
                            <a href="forecastPublicExtended.asp#Period0" target="_blank">
                                <img src="./images/wimages/b_cloudy.gif" height="50px" width="50px" alt="weather image">        
                            </a>                    </div>
                        <div style="position:absolute; top:25px; left:57px; text-align:left; height:47px; width:90px;">
                            Sunny Breaks                            </div>
                    </div>

                    <div class="TodaysForecastContainerInner">
                        <div style="font-size:12px;"><u>This afternoon</u></div>
                        <div style="position:absolute;top:17px;left:3px;">
                            <a href="forecastPublicExtended.asp#Period0" target="_blank">
                                <img src="./images/wimages/b_pcloudy.gif" height="50px" width="50px" alt="weather image">       
                            </a>                    </div>
                        <div style="position:absolute; top:25px; left:57px; text-align:left; height:47px; width:90px;">
                            Mix of Sun and Cloud                            </div>
                    </div>

今天早上
晴天休息
今天下午
太阳和云的混合

问题是绝对位置内联样式，它们没有类或id，我希望我可以添加一个类名并删除带有“This morning”的div上的内联样式，包含图像的div，还可以删除带有说明的链接和div（例如Sunny Breaks）也改变了今天所有的预测容器，因为它有大约4个预测。使其类似于：

<div class="day>This morning</div><div class="thumbnail"><img src="sample.jpg"></div><div class="description">Sunny Breaks</div>

---

在客户机上执行此操作比在服务器上更容易

此jQuery+Javascript将清除内联样式，并为每个样式应用类名：

$(document).ready(function() { 
     var target = $('.TodaysForecastContainerInner div')
         for(var x=0;x< target.length;x++) {
               target.eq(x).attr('style','');
               target.eq(x).addClass("A_"+x)
         }   
})

$（文档）.ready（函数（）{
var target=$（'.TodaysForCastContainerIner div'
对于（var x=0；x

结果:

<div class="TodaysForecastContainerInner">
    <div style="" class="A_0"><u>This morning</u></div>
    <div style="" class="A_1">
        <a target="_blank" href="forecastPublicExtended.asp#Period0">
            <img height="50px" width="50px" alt="weather image" src="./images/wimages/b_cloudy.gif">        
        </a>                    </div>
    <div style="" class="A_2">
        Sunny Breaks                            </div>
</div>

<div class="TodaysForecastContainer">
  <div class="TodaysForecastContainerInner">
    <div class="day">This morning</div>
    <div class="thumbnail"><img src="./images/wimages/b_cloudy.gif"></div>
    <div class="description">
      Sunny Breaks
    </div>
  </div>
  <div class="TodaysForecastContainerInner">
    <div class="day">This afternoon</div>
    <div class="thumbnail"><img src="./images/wimages/b_pcloudy.gif"></div>
    <div class="description">
      Mix of Sun and Cloud
    </div>
  </div>

您可以使用样式表使其外观符合您的要求。
查看库。它可以使用PHP进行类似jQuery的操作。此代码基本上完成了您正在尝试执行的操作：

<?php

include 'phpQuery-onefile.php';

$text = <<<EOF
<div class="TodaysForecastContainer">
    <div class="TodaysForecastContainerInner">
        <div style="font-size:12px;"><u>This morning</u></div>
        <div style="position:absolute;top:17px;left:3px;">
                <a href="forecastPublicExtended.asp#Period0" target="_blank">
                        <img src="./images/wimages/b_cloudy.gif" height="50px" width="50px" alt="weather image">        
                </a>
        </div>
        <div style="position:absolute; top:25px; left:57px; text-align:left; height:47px; width:90px;">
            Sunny Breaks
        </div>
    </div>
    <div class="TodaysForecastContainerInner">
        <div style="font-size:12px;"><u>This afternoon</u></div>
        <div style="position:absolute;top:17px;left:3px;">
            <a href="forecastPublicExtended.asp#Period0" target="_blank">
                <img src="./images/wimages/b_pcloudy.gif" height="50px" width="50px" alt="weather image">       
            </a>
        </div>
        <div style="position:absolute; top:25px; left:57px; text-align:left; height:47px; width:90px;">
            Mix of Sun and Cloud
        </div>
    </div>
EOF;

$doc = phpQuery::newDocumentHTML( $text );

$containers = pq('.TodaysForecastContainerInner', $doc);
foreach( $containers as $container ) {
    $div = pq('div', $container);

    $div->eq(0)->removeAttr('style')->addClass('day')->html( pq( 'u', $div->eq(0) )->html() );  
    $div->eq(1)->removeAttr('style')->addClass('thumbnail')->html( pq( 'img', $div->eq(1))->removeAttr('height')->removeAttr('width')->removeAttr('alt') );
    $div->eq(2)->removeAttr('style')->addClass('description');  
}

print $doc;

谢谢你的回复不幸的是我没有得到你的回复，这里是我的测试点。你能告诉我你是怎么做的吗这里是我的php//find all foreach（$html->find（'.TodaysForecastContainerInner div'）as$e）echo$e->innertext
'；另外，我在$（document）.ready（function（）{var target=$）上出错了（我不知道怎么了这是源代码，你可以查看我放在上面的php谢谢你的评论我在$text=Hrm上出现语法错误了…我只是通过粘贴和复制再次尝试，它对我有效。不过没什么大不了的。“$text=
