regex - Powershell Select-String 列出多个匹配项

Question

我正在尝试根据一些 XML 文件的单词列表进行一些模式匹配。

我有以下内容：

$Result = Get-ChildItem -Recurse $FullPath\*.xml |
  Select-String -Pattern $WordList |
    Select-Object Path, Pattern, Line, LineNumber

我的问题出现在同一行代码中有多个匹配项时，

例如，如果 $WordList = "AA","AACC"，则该行是：

"This is a test line AA, BB, AACC, KK"

$Result 将只是基于第一个单词 (AA) 的单行匹配。但它不会给我所有三个结果，一个是基于“AA”的两个匹配，另一个是基于“AACC”的匹配，都在同一行。

---

当前 $Result:

Path Pattern Line LineNumber
**   AA      This is a test line AA, BB, AACC, KK 12

理想的 $Result:

Path Pattern Line LineNumber
**   AA      This is a test line AA, BB, AACC, KK 12
**   AA      This is a test line AA, BB, AACC, KK 12
**   AACC    This is a test line AA, AABB, AACC, KK 12

Answer 1

$WordList = "AA","AACC"
$Result = $WordList | Foreach { 
    Get-ChildItem .\Test\*.txt |
        Select-String -Pattern $_ } |
            Select-Object Path, Pattern, Line, LineNumber 

输出：

$Result

Path Pattern Line                            LineNumber
---- ------- ----                            ----------
**   This is a test line AA, BB, AACC, KK 12 1
**   This is a test line AA, BB, AACC, KK 12 1
