如何使用ant盘点任务countfilter [英] how to use ant count task countfilter

问题描述

我试着去计算该行出现的次数的这是否buildlist需要编译：真正的在文件中。我尝试以下code，但它不会拿起计数

Im trying to count the number of occurences of the line "Does this buildlist need compile: true" in a file. I tried the following code, but it does not pick up the count

<concat>
<fileset file="@{logPathInTestSetup}" />
    <filterchain>
        <tokenfilter>
            <ct:countfilter property="noOfCompiledBuildlists" contains="Does this buildlist need compile:\s*(true)" override="true">
            <ct:counteach propertyprefix="count." select="\1" />
            </ct:countfilter>
         </tokenfilter>
         <ct:stopfilter />
      </filterchain>
</concat>

当我尝试计算这种buildlist需要编译，柜台工作，我得到正确的值。所以绝对没有与正则表达式中的问题。是否有人可以帮忙吗？
谢谢，
Aarthi

When I try counting "Does this buildlist need compile:", the counter works and I get the correct value. So there is definitely a problem with the regex. Can someone please help? Thanks, Aarthi

推荐答案

您并不需要一些额外的工作，但是蚂蚁1.7.1+为＆LT; CONCAT＆GT; 必须的资源。结果
下面是从蚂蚁手动resourcecount 结果略有调整的例子
给定的输入，foobar.txt：结果

You don't need some extra task, but Ant 1.7.1+ as <concat> has to be resource.
Here's a slightly adapted example from ant manual resourcecount
given input, foobar.txt :

Does this buildlist need compile: true
whatever
Does this buildlist need compile: false
The quick brown fox
jumps over the lazy dog
Does this buildlist need compile: true
Does this buildlist need compile: false
Does this buildlist need compile: true
foo
blablabla
Does this buildlist need compile: true

例如蚂蚁脚本：结果

example ant script :

<project>
 <property name="file" value="foobar.txt"/>
  <resourcecount property="file.lines">
   <tokens>
    <concat>
     <filterchain>
      <linecontainsregexp>
       <regexp pattern="Does this buildlist need compile:\s*(true)"/>
      </linecontainsregexp>
     </filterchain>
     <fileset file="${file}"/>
    </concat>
   </tokens>
  </resourcecount>
  <echo>The file '${file}' has ${file.lines} lines.</echo>
</project>

输出：结果

[echo] The file 'foobar.txt' has 4 lines.

结果
修改结果
要获取不匹配的线，意味着否定你的正则表达式，只需使用：结果

EDIT
To get the lines that do not match, means negate your regex, simply use :

</linecontainsregexp negate="true">
