if(window.IPCallBack) {IPCallBack({"ip":"14.125.60.161","pro":"广东省","proCode":"440000","city":"珠海市","cityCode":"440400","region":"","regionCode":"0","addr":"广东省珠海市电信","regionNames":"","err":""});}

$txt = "if(window.IPCallBack) {IPCallBack({"ip":"14.125.60.161","pro":"广东省","proCode":"440000","city":"珠海市","cityCode":"440400","region":"","regionCode":"0","addr":"广东省珠海市电信","regionNames":"","err":""});}"
$asResult = StringRegExp($txt,'\bcity\b.*\bcityCode\b',1)
If @error = 0 Then
MsgBox(0, "结果", $asResult[0])
EndIf
这样能提取到城市为 city":"珠海市","cityCode 可是我只想要"珠海市"
自己不懂正则，所以请教下大家怎么样可以只提取“珠海市”

Local $sSource = 'if(window.IPCallBack) {IPCallBack({"ip":"14.125.60.161","pro":"广东省","proCode":"440000","city":"珠海市","cityCode":"440400","region":"","regionCode":"0","addr":"广东省珠海市 电信","regionNames":"","err":""});}'
;~MsgBox(0, '源字符串', $sSource)
Local $aSRE = StringRegExp($sSource, 'city":"([^"]+)', 1)
If Not @Error Then MsgBox(0, '匹配数量: ' & UBound($aSRE), '其中[0]元素为: ' & $aSRE[0])

牛人.借楼问个小白问题.
假设有字符
ab
abc
abcd
如果我只想要提取字符ab,abcd,除了\wb(?=[^c])|\w{3}(?=d). 这个以外,还有别的方案吗?
