又一不错的应用-正则来查找替换字符串

以下这段代码截取自某一网页源码：
onClick="MM_openBrWindow('../photo/nlife/sfc/pages/O'Connors_jpg.htm','RD','width=456,height=368')"
onClick="MM_openBrWindow('../photo/nlife/sfc/pages/Trad'r Sam_jpg.htm','RD','width=456,height=368')"
onClick="MM_openBrWindow('../photo/nlife/sea/pages/Mondo's Beach Pub_jpg.htm','RD','width=456,height=368')"
onClick="MM_openBrWindow('../photo/nlife/tam/pages/Mirage (Moet's) _jpg.htm','RD','width=456,height=368')"
onClick="MM_openBrWindow('../photo/nlife/tem/pages/Macayo's - N Central_jpg.htm','RD','width=456,height=368')">
onClick="MM_openBrWindow('../photo/nlife/tem/pages/RT O'Sullivans_jpg.htm','RD','width=456,height=368')"
onClick="MM_openBrWindow('../photo/nlife/nyc/pages/Pat O'Hurley's Bar & Grill_jpg.htm','RD','width=456,height=368')"
这里需要把链接中的'批量替换成'\，注意链接中有空格、特殊字符（横杠、括号、&等），有的地方'还出现不止一次。替换过程中还不能把其他地方的'和链接中的其他内容替换掉，我想到用DW的正则替换，请问这样的正则表达式要怎么写呢？
