使用 Powershell 读取和解析结构化文本文件

Question

我正在尝试读取从另一个程序生成的文本文件并解析它们以执行其他操作。

This 主题很接近，但我正在阅读的文件有更多 "structuring"，因为缺少更好的词。这是我正在阅读的文件的示例，供参考：

data:extend(
{
{
type = "buildformula",
name = "item1",
active = false,
buildtime = 3,
ingredients =
{
  {"ingredient1", 1},
  {"ingredient2", 4},
  {"ingredient3", 5}
},
result = "finished item 1"
},        

{
type = "buildformula",
name = "item2",
active = true,
buildtime = 12,
ingredients =
{
  {"ingredient1", 2},
  {"ingredient2", 3}
},
result = "finished item 2"
},
}
)

另一个建议是 post 引用了 ConvertFrom-String 命令，它似乎具有我需要的功能，但我仍然没有得到任何结果。

最后是我拥有的最新代码：

    $TemplateAdr = @'
{
type = "buildformula",
name = "item1",
active = false,
buildtime = 3,
ingredients =
{
  {"ingredient1", 1},
  {"ingredient2", 4},
  {"ingredient3", 5}
},
result = "finished item 1"
},        

{
type = "buildformula",
name = "item2",
active = true,
buildtime = 12,
ingredients =
{
  {"ingredient1", 2},
  {"ingredient2", 3}
},
result = "finished item 2"
},
'@
$output=Get-Content -Path "C:\temp\itembuilds.txt" |  ConvertFrom-String -TemplateContent $TemplateAdr

我是 PowerShell 的新手，但我觉得这是可能的。

您的 $TemplateAdr 模板没有这样标记。

试试这个：

$TemplateAdr = @'
data:extend(
\{
\{
type = "{Type*:buildformula}",
name = "{Name:item1}",
active = {[bool]Active:false},
buildtime = {[int]BuildTime:3},
{Ingredients:ingredients =
\{
  \{"{IngredientName*:ingredient1}", {[int]IngredientCount:1}\},
  \{"{IngredientName*:ingredient2}", {[int]IngredientCount:4}\},
  \{"{IngredientName*:ingredient3}", {[int]IngredientCount:5}\}
\},}
result = "{[string]Result:finished item 1}"
\},

\{
type = "{Type*:buildformula}",
name = "{Name:item2}",
active = {[bool]Active:true},
buildtime = {[int]BuildTime:12},
{Ingredients:ingredients =
\{
  \{"{IngredientName*:ingredient1}", {[int]IngredientCount:2}\},
  \{"{IngredientName*:ingredient2}", {[int]IngredientCount:3}\}
\},}
result = "{[string]Result:finished item 2}"
\},
\}
)
'@

Get-Content -Path "C:\temp\itembuilds.txt" |
    ConvertFrom-String -TemplateContent $TemplateAdr |
        Select-Object -Property Type,Name,Active,BuildTime,@{Name='Ingredients';Expression={$_.Ingredients.Items}}

花括号使用 \ 转义。我已经为某些属性明确指定了 PowerShell 类型（您可能不希望这样）。我已经使用 Select-Object 将 ingredients 列表映射到新的属性。

随意更改字段规范中的属性名称 ({PropertyName:whatever})。
