Ant 如何将从文件中读取的值转换为属性值?

问题描述：

文件看起来像:

a1,b1
a2,b2
...

我知道值a2".如何将值b2"转化为属性值.

I know the value "a2". How to get the value "b2" into a property value.

我知道如何通过以下方式选择包含a2"的行:

I know how to select line which contains "a2" by:

<linecontains>
  <contains value="a2"/>
</linecontains>

但是我不知道如何将属性值设置为b2".我随时为您提供更多信息.

But I do not know how to set a property value to "b2". I am at your disposal for more other information.

答

以下对我有用:

<loadfile srcfile="data" property="result">
     <filterchain>
           <linecontains>
                <contains value="a2"/>
           </linecontains>
           <tokenfilter>
                <replacestring from="a2," to=""/>
           </tokenfilter>
    </filterchain>
</loadfile>
<echo message="${result}"/>

正如您所指出的，首先将选择a2"行.然后令牌过滤器将 a2 和冒号替换为空.希望有所帮助.

As you pointed out, first the line the the 'a2' will be selected. The tokenfilter then replaces a2 and the colon with nothing. Hope that helps.
