假设页面为test.html,且最后一个表格Part Information的内容不固定，可能是1行也可能是多行。
如果要求抓蓝色字体部分怎么做？寻求解决方案。
回复讨论(解决方案)
循环table的tr，直接抓取td的值
这个页面本身返回数据的时候就有蓝色在上面吗？若是，则

这个正则这么用啊？感谢！
preg_match_all('#
如果有的页面取的值的项不同，怎么求那些项？
例如：[10] => *DYNP-770266110-00* ，有时候是[12] => *DYNP-770266110-00*。
但是前一项的值都是一样的，只是键值不同。例：[9] => Customer 客户这项。
那就是你的问题了
一般说明文字与数据总是配对的，并且说明文字在前，数据在后
