[英]Using Powershell, how can I export and delete csv rows, where a particular value is *not found* in a *different* csv?
[英]How can I export multiple objects to different CSV columns in PowerShell
我抓取了一个网站,我真正想要的是拥有一个CSV文件,该文件在单独的列中分别包含抓取的字符串。
$page = Invoke-WebRequest -Uri "SomeURL"
$obj = $page.ParsedHtml.Body.GetElementsByTagName('SomeTag') |
Where {$_.GetAttributeNode('class').Value -eq 'someValue'}
$obj1 = $page.ParsedHtml.Body.GetElementsByTagName('SomeAnotherTag') |
Where {$_.GetAttributeNode('class').Value -eq 'someAnotherValue'}
$obj2 = $page.ParsedHtml.Body.GetElementsByTagName('yetAnotherTag') |
Where {$_.getAttributeNode('class').Value -eq 'yetAnotherValue'}
$locations = $obj.InnerText
$locations1 = $obj1.InnerText
$locations2 = $obj2.InnerText
$toExport0 = $locations | Select-Object @{Name='locations';Expression={$_}}
$toExport1 = $locations1 | Select-Object @{Name='AnotherSetOflocations';Expression={$_}}
$toExport2 = $locations2 | Select-Object @{Name='YetAnotherSetOflocations';Expression={$_}}
$locations
, $locaitons1
和$locations2
中的每个包含刮擦的字符串。 当我输出它们时,就像这样:
word another word yet another word . . .
我想要的输出是(将其导出到以列分隔的CSV文件中):
locations,anotherSetOfLocations,YetAnotherSetOfLocations word,...,... another word,...,... yet another word,...,... . . .
在这些位中:
$toExport0 = $locations | select-object @{Name='locations'; Expression={$_}}
您正在创建三个单独的对象,这些对象不适用于CSV创建。 删除这些行,找到位置后立即执行所有操作。
您需要一个具有三个属性的对象:
$toExport = [PSCustomObject]@{
'locations' = $locations
'anotherSetOfLoc' = $locations2
'locations3' = $locations3
}
$toExport | Export-Csv out.csv -NoTypeInformation
