Nant 中的 xmlpoke - 如何更新找到的字符串的所有实例

发布于 2024-08-31 09:25:29 字数 375 浏览 4 评论 0原文

您好，我在 Nant 构建脚本中使用 Xpath 来更改开发环境和其他环境之间的一些配置变量。

我从这个例子中获取了语法：

这个例子看起来像这样：

<xmlpoke
    file="config01/app.config"
    xpath="/configuration/appSettings/add[@key='AppName']/@value"
    value="TradeMonster">
</xmlpoke>

我想要的是与此类似的东西来搜索我的连接字符串并找到“localhost\SqlExpress”的所有实例，然后将它们更改为“localhost”

是这样的可能的？

Hi I am using Xpath in my Nant build script to change some config variables between development and my other environments.

I have taken the syntax from this example:

The example looks like this:

<xmlpoke
    file="config01/app.config"
    xpath="/configuration/appSettings/add[@key='AppName']/@value"
    value="TradeMonster">
</xmlpoke>

What I would like is something similar to this to search my connection strings and find all instances of "localhost\SqlExpress" and just change them to just "localhost"

Is this possible?

在这里玩弄一个快速而肮脏的脚本......

如果您确定每个文件中只有一个连接字符串元素，您可以使用 xmlpeek 和 xmlpoke 的组合来完成此操作代码>.使用某些 C# 可以更轻松地修改字符串，因此使用脚本任务来执行正则表达式搜索和替换：

 <script language="C#" prefix="custom" >
      <code>
        <![CDATA[
          [Function("fix")]
          public static string Fix(string input) {
              return Regex.Replace(input, @"localhost\\\w+", "localhost");
          }
        ]]>
      </code>
  </script>

<!-- Get the existing connection string -->
<xmlpeek
    file="config01/app.config"
    xpath="/configuration/connectionStrings/add[@contains(@connectionString,'localhost\')]/@connectionString"
    property="connectionstring">
</xmlpeek>

<!-- Write back the modified connection string -->
<xmlpoke
    file="config01/app.config"
    xpath="/configuration/connectionStrings/add[@contains(@connectionString,'localhost\')]/@connectionString"
    value="${custom::fix(connectionstring)}">
</xmlpoke>

Toying with a quick'n dirty script here....

If you're sure there is only one connectionstring element in each file you can accomplish this with a combination of xmlpeek and xmlpoke. Modifying the string is easier done with some C#, therefore using a script task to do a regex search and replace:

 <script language="C#" prefix="custom" >
      <code>
        <![CDATA[
          [Function("fix")]
          public static string Fix(string input) {
              return Regex.Replace(input, @"localhost\\\w+", "localhost");
          }
        ]]>
      </code>
  </script>

<!-- Get the existing connection string -->
<xmlpeek
    file="config01/app.config"
    xpath="/configuration/connectionStrings/add[@contains(@connectionString,'localhost\')]/@connectionString"
    property="connectionstring">
</xmlpeek>

<!-- Write back the modified connection string -->
<xmlpoke
    file="config01/app.config"
    xpath="/configuration/connectionStrings/add[@contains(@connectionString,'localhost\')]/@connectionString"
    value="${custom::fix(connectionstring)}">
</xmlpoke>
