动态字符串替换 [英] Dynamic String Replace

问题描述

我有一个动态生成的字符串，该字符串基本上是JSON字符串.每次生成字符串时，字符串中的几个单词都会更改，我该如何解析这些单词，以便用自己的某个常量单词替换它们.

字符串看起来像这样
"end_location":{" Za ":17.44716，" $ a ":78.37790999999993}，"start_address":"Mumbai Rd，Madhura Nagar Colony，Madhapur，Hyderabad，Andhra印度普拉达什，" start_location:{" Za :17.4243，" $ a :78.37761999999998}，

在此示例字符串之前和之后有更多数据.现在我得到的结果是Za和$ a(以粗体显示)，它们总是不断更改为不同的值.我该如何用一个常数词替换这些词.

Hi,

I have a string which is generated dynamically, the string is basically an JSON string. Each time the string is generated few words in the string gets changing, how can i parse these words so that i replace them with some constant word of my own.

The string looks like this
"end_location":{"Za":17.44716,"$a":78.37790999999993},"start_address":"Mumbai Rd, Madhura Nagar Colony, Madhapur, Hyderabad, Andhra Pradesh, India","start_location":{"Za":17.4243,"$a":78.37761999999998},

With even more data before and after this sample string. Now the result what i get has Za and $a(in bold) which always keeps changing to different value. How can i replace these words with some constant word.

a :78.37790999999993}，" start_address:" Mumbai Rd，Madhura Nagar Colony，印度，安得拉邦海得拉巴的Madhapur"，"start_location":{" Za ":17.4243，"

a":78.37790999999993},"start_address":"Mumbai Rd, Madhura Nagar Colony, Madhapur, Hyderabad, Andhra Pradesh, India","start_location":{"Za":17.4243,"

a ": 78.37761999999998}，

在此示例字符串之前和之后有更多数据.现在我得到的结果是Za和

a":78.37761999999998},

With even more data before and after this sample string. Now the result what i get has Za and

a(粗体)，它们总是不断更改为不同的值.我该如何用一个常数词代替这些词.
