如果用正侧表达式替换里面的数字？
<content   img_url= " ">
<pageinfo1   page_id= "12 ">
<picture1     effect= " "   width= "383 "   x= "33 "   y= "0 "   />
<picture2     effect= " "   width= "383 "   x= "483 "   y= "0 "   />
</pageinfo1>
<pageinfo2   page_id= "12 ">
<picture1     effect= " "   width= "383 "   x= "33 "   y= "0 "   />
<picture2     effect= " "   width= "383 "   x= "483 "   y= "0 "   />
</pageinfo2>
</content>

如上面的xml
我想把   节点的数字去掉pageinfo1     pageinfo2   替换成   pageinfo
picture1   picture2   替换成picture
不带数字？如何写这个正侧？谢谢。

------解决方案--------------------
假设上面这段xml是s
s.replaceAll( " <(\\w*)\\d{1} ", " <$1 ");
------解决方案--------------------
String.replaceAll( "pageinfo[0-9]+ ", "pageinfo ");

String.replaceAll( "picture[0-9]+ ", "picture ");
------解决方案--------------------
killme2008 的方法不错！学习了。

但是忽略了 </pageinfo1> ,写成下边这样就更完美了:)

s.replaceAll( "( <[/]?\\w*)\\d{1} ", "$1 ");
