实现正则表达式的迭代替换

Question

正则递归，PHP可以实现，js 的没见过，不知道是否支持

Answer 1

莫非这是天书?/re/.replace(string, function(arg[,arg n]){});

Answer 2

没看出什么来 reg2 内层匹配 本列可用 /ON/ig 根本没有用一个 replace 就够了

Answer 3

只是举了例子 不一定是ON 只是符合reg2的定义

Answer 4

譬如是要将 ???x???x???<??x?????x??>??x??x??
转化为     ???x???x???<??xx??>??x??x??
去除<>之间的xx之间的内容 replace恐怕不够吧

Answer 5

<script language="javascript">
var a="???x???x??? <??x???x??>??x??x??" 
alert(a.replace(/(<[^>]*?)x[^x]*?x([^>]*?>)/,"$1$2"))</script>
一般的都可以   除非一些特殊情况

Answer 6

<script language="javascript">
var a="???x???x??? <??x???x??>??x??x??" 
alert(a.replace(/(<[^>]*?)x[^x]*?x([^>]*?>)/,"$1$2"))</script>
一般的都可以   除非一些特殊情况

Answer 7

铭轩兄的方式是可以的
建立模式1的匹配 然后保留模式2以外的部分
然后模式1替换成 $1 模式2替换 $2
利用循环test完成模式1中所有模式2的替换此例还能否用递归解决呢

Answer 8

不需要循环  他自己有个g匹配
<script language="javascript">
var a="???x???x??? <??x???x??>??x??x??<??x???x??>11<??x???x??>22x???x" 
alert(a.replace(/(<[^>]*?)x[^x]*?x([^>]*?>)/g,function(a,b,c){ return b+c;}))</script>
