我正在尝试抓取一个网站，以便随着时间的推移自动跟踪我在Rocket League播放列表中的排名。我的想法是，我要抓住与播放列表相对应的数字，然后将其放入csv中以作参考。我已经能够获取该网页的HTML，但似乎无法有效地解析出我想要的数字。
这是我收集网页信息的方式：
$tracker = Invoke-WebRequest -Uri
https://rocketleague.tracker.network/profile/steam/adammast12
$tracker.RawContent
这是我感兴趣的RawContent部分：

我想从与排名播放列表相关的系列中获取信息。例如，我需要能够获得与“ Ranked Duel 1v1”和“ Ranked Doubles 2v2”等相对应的第一个值，以便可以将该数字保存在csv中。
我尝试过按这样的字符串搜索：
$data = $tracker.tostring() -split "[`r`n]" | select-string "Ranked Standard 3v3"
这是给我的结果：
Ranked Standard 3v3
Ranked Standard 3v3
Ranked Standard 3v3
Ranked Standard 3v3
Ranked Standard 3v3
Ranked Standard 3v3
{ name: 'Ranked Standard 3v3', data:
[994,994,994,994,994,994] },
{ name: 'Ranked Standard 3v3', data: [0,0,0,0,0,0] },
我不确定如何从那里解析它。感谢您的帮助！

以下是如何获取“未跟踪”部分的示例：
# result ArrayList
$results = New-Object System.Collections.ArrayList
# REST Get
$tracker = Invoke-WebRequest -Uri https://rocketleague.tracker.network/profile/steam/adammast12
# HTML data
# $tracker.RawContent
# split by carriage return + new line
# select the JSON with "name:" in it
$data = $tracker.tostring() -split "`r`n" | Select-String "name:"
# Un-Ranked data
$unranked = $data | Select-String "name: 'Un-Ranked'"
# Split at []'s
$unrankedSplit = $unranked.ToString().Split('[').Split(']')
# this yields a result like this:
# { name: 'Un-Ranked', data:
# 1270,1270,1270,1270,1270,1251
# },
#
# Split again at the second position on each comma, position [1]
# since PowerShell is zero-based indexing
$unrankedSplitChild = $unrankedSplit[1].Split(',')
# loop through each item with custom objects
foreach($item in $unrankedSplitChild)
{
# create a PSCustomObject and add to to the results
$results += [PSCustomObject]@{Category="Un-Ranked";Data=$item}
}
# throw the results to the console
$results | Format-Table -AutoSize
