存储ANT正则表达式中的Excel文件 [英] store ANT regex in an excel file

问题描述

我为此我使用的是文件集和正则表达式来得到我的文件，并获得该文件中的前pression创建一个Ant脚本。结果
我还需要存储前pression呈S preadsheet，这我不知道该怎么做。结果
我已经学会了什么地方，我可以用replaceregexp，但我不知道我该怎么做。

I am creating an ANT script for which I am using a fileset and a regex to get my file and to get an expression in that file.
I also need to store the expression in a spreadsheet, which I am not sure how to do it.
I have learned somewhere that I could use replaceregexp, but I am not sure how do I do that.

我用的目标任务做对文件和前pression搜索。

I have used target tasks to do the search for the file and expression.

推荐答案

ANT是不是一种编程语言，所以这是不是解决一个小问题。下面的例子使用：

ANT is not a programming language so this is not a trivial problem to solve. The following example uses:

• 常规任务实现解析逻辑


• 的Apache POI 来编写Excel文件


• 的Apache常春藤来管理第三方的jar依赖关系。

• groovy task implement the parsing logic
• Apache POI to write the excel file
• Apache ivy to manage the 3rd party jar dependencies.

这是例子计算在资源子目录字符串一出现的次数：

This is example counts the number of occurrences of the string "one" in the resources sub directory:

├── build.xml
├── resources
│   ├── file1.txt
│   ├── file2.txt
│   └── file3.txt
└── results.xlsx

结果也被写入到Excel文件results.xlsx

Results are also written to an excel file "results.xlsx"

parse-files:
   [groovy] File:file1.txt Count:1
   [groovy] File:file2.txt Count:0
   [groovy] File:file3.txt Count:1

的build.xml

<project name="demo" default="parse-files" xmlns:ivy="antlib:org.apache.ivy.ant">

  <available classname="org.apache.ivy.Main" property="ivy.installed"/> 

  <target name="parse-files" depends="init" >

    <fileset dir="resources" id="filesToParse" includes="*.txt"/>

    <groovy>
      import org.apache.poi.ss.usermodel.Workbook
      import org.apache.poi.xssf.usermodel.XSSFWorkbook
      import org.apache.poi.ss.usermodel.CreationHelper
      import org.apache.poi.ss.usermodel.Sheet
      import org.apache.poi.ss.usermodel.Row

      Workbook wb = new XSSFWorkbook();
      Sheet sheet = wb.createSheet("Regexp results");
      CreationHelper helper = wb.getCreationHelper();
      rowpos = 0

      project.references.filesToParse.each {
        def file    = it.file
        def content = file.text

        // Search file
        def findOneStr = content =~ /one/

        println "File:${file.name} Count:${findOneStr.count}"

        // Save to Excel row
        Row row = sheet.createRow(rowpos++)
        row.createCell(0).setCellValue(helper.createRichTextString(file.name));
        row.createCell(1).setCellValue(findOneStr.count);
      }

      // Save excel file
      new File("results.xlsx").withOutputStream {
        wb.write(it)
      }
    </groovy>
