  1.   

    <script>
    str = "<math>aaaaa</math><math>bbbbb</math>";
    alert(str.match(/\<math.*?<\/math>/gi));
    </script>
      

  2.   

    <script>
    str = '<math title="((a,b),(c,d))^-1 = 1/(ad-bc)((d,-b),(-c,a))" xmlns="http://www.w3.org/1998/Math/MathML"><mstyle mathcolor="blue" fontfamily="serif" displaystyle="true"><msup>............</math><span style="font-size: 1em; font-family: serif;"><math><sdfsdf></sdfads></math></span>.......';
    alert(str.match(/\<math.*?<\/math>/gi));
    </script>
    你自己看吧. 结果将是以,分隔的数组.
      

  3.   

    比如你把最后的</math>换行就取不到了
      

  4.   

    /<math(.*?)>(.|\n|\r\n|\r)*?</math>/igm 这个才是正确的，不过还是谢谢你
      

  5.   

    <math(>|\s[^>]*>).*?</math>
