<?xml version="1.0" encoding="utf-8"?><data>
<item url="movie.asp?id=5" target="_blank" img="Xml/hot/1.jpg" thumb="Xml/hot/1i.jpg" />
<item url="movie.asp?id=11259" target="_blank" img="Xml/hot/2.jpg" thumb="Xml/hot/2i.jpg" />
<item url="/" target="_blank" img="Xml/hot/3.jpg" thumb="Xml/hot/3i.jpg" />
<item url="movie.asp?id=587" target="_blank" img="Xml/hot/4.jpg" thumb="Xml/hot/4i.jpg" />
<item url="movie.asp?id=9270" target="_blank" img="Xml/hot/5.jpg" thumb="Xml/hot/5i.jpg" />
</data>

搜索指定行列id=后5位数字，然后写入替换
例如2行id=后面5位数字，然后写入替换
怎么写，谢谢

$str =  '<?xml version="1.0" encoding="utf-8"?><data>'&@CRLF& _
                '<item url="movie.asp?id=5" target="_blank" img="Xml/hot/1.jpg" thumb="Xml/hot/1i.jpg" />'&@CRLF& _
                '<item url="movie.asp?id=11259" target="_blank" img="Xml/hot/2.jpg" thumb="Xml/hot/2i.jpg" />'&@CRLF& _
                '<item url="/" target="_blank" img="Xml/hot/3.jpg" thumb="Xml/hot/3i.jpg" />'&@CRLF& _
                '<item url="movie.asp?id=587" target="_blank" img="Xml/hot/4.jpg" thumb="Xml/hot/4i.jpg" />'&@CRLF& _
                '<item url="movie.asp?id=9270" target="_blank" img="Xml/hot/5.jpg" thumb="Xml/hot/5i.jpg" />'&@CRLF& _
        '</data>'
$sn = StringRegExpReplace($str,"(?<=id\=)[0-9]{5}","替换")
MsgBox(0,"",$sn)

这样?

列的指定呢？
<?xml version="1.0" encoding="utf-8"?><data>
<item url="movie.asp?id=5" target="_blank" img="Xml/hot/1.jpg" thumb="Xml/hot/1i.jpg" />
针对这一列

假設樓上變量str值寫入文件str.xml中
$File = Fileopen("str.xml",0)
   $rLine = Filereadline($File,2)
   $rn = StringRegExpReplace($rLine,"(?<=id\=)[0-9]{*}","替换")
   MsgBox(0,"",$rn)
