如何在Powershell中添加简单搜索并替换此循环？

Question

到目前为止，我写了这篇文章，它贯穿始终，完全符合我的要求，现在我被困住了。我似乎无法打开新创建的$ NOSPACE.shtml并用变量$ SPACE替换一个单词。请帮助一点？

$CITYLIST=import-csv CityList.txt
$CITYLIST | FOREACH-OBJECT { $_ }
FOREACH ($Item in $CITYLIST) { 
$Item.City
$NOSPACE=$Item.City.replace(" ","_")
$SPACE=$Item.City
Add-Content _citylist.shtml "`n<a class=`"cityareaslist`" href=`"`/$NOSPACE.shtml`">    $SPACE<`/a>" ; Copy-Item index.shtml "$NOSPACE.shtml"
}

Answer 1

(Get-Content "$NOSPACE.shtml") | 
Foreach-Object {$_ -replace 'word',$SPACE} | 
Set-Content "$NOSPACE.shtml"
