　　QueryListrules(array)规则字段解释下面几个复杂的解释

　　QueryList 规则（数组 $rules）

　　//采集规则$rules = array( '规则名' => array('jQuery选择器','要采集的属性'[,"标签过滤列表"][,"回调函数"]), '规则名2' => array('jQuery选择器','要采集的属性'[,"标签过滤列表"][,"回调函数"]), ..........);//注:方括号括起来的参数可选

　　//采集规则$rules = [ //采集img标签的src属性，也就是采集页面中的图片链接 'name1' => ['img','src'], //采集class为content的div的纯文本内容， //并移除内容中的a标签内容，移除id为footer标签的内容，保留img标签 'name2' => ['div.content','text','-a -#footer img'], //采集第二个div的html内容，并在内容中追加了一些自定义内容 'name3' => ['div:eq(1)','html','',function($content){ $content += 'some str...'; return $content; }]];

　　规则字段说明

　　下面分别解释几个复杂的字段。

　　1.要采集的属性

　　值有以下3种：

　　2.tag 过滤列表

　　设置此选项可用于过滤不需要的内容。多个值用空格分隔。有如下两条规则：

　　 这是中文内容，这里有个链接</a> 这里有一段广告 这里还有一段广告

　　获取class为article的元素的内部内容，但不想要那段广告文字，则可以设置采集规则为：

　　//采集规则$rules = [ 'content' => ['.article','html','-.ad1 -.ad2']];

　　意思是：采集class是article元素里面的html内容，去掉class为ad1，class为ad2的元素的内容。

　　现在得到的内容是：

　　这是中文内容，这里有个链接

　　在实际采集中，我们一般不想要采集其他人的外链，而是想去掉内容中的链接。这时候如果把filter改成-.ad1 -.ad2 -a，采集就会到达内容为：

　　这是中文内容，

　　链接去掉了，但实际上我们要保存链接的文本内容，所以过滤器应该改为：-.ad1 -.ad2 a，所以采集到达的内容是：<//p

ppre class="prettyprint linenums prettyprinted" style=""ol class="linenums"li class="L0"codespan class="pun"这是中文内容，这里有个链接/span/code/li/ol/pre/p

p用法/p
