回复 17# went


   感谢大侠帮忙, 测试了一下, 最后取的示例错了
链接
http://go.microsoft.com/fwlink/?LinkID=113392

取到的结果:
------Example 4: Use Filters with Set-Content------
The following command set the content all *.txt files in the C:\Temp directory to the Value empty.


应该取:
Set-Content -Path C:\Temp\* -Filter *.txt -Value "Empty"

规律是:如果一行开头包含 powershell  结尾包含复制,它的下一行就是要取的内容

$r.ParsedHtml.getElementsByTagName('h3') | Where-Object { $_.id -match '^example' } | foreach {
    '------{0}------' -f $_.innerText
    $ele = $_
    while($ele.tagName -ne 'PRE'){ $ele = $ele.nextSibling }
    $ele.innerText
}
