在 Powershell 中解析 XML 文件

Question

我正在尝试从 Yahoo 检索汇率

$browser = New-Object System.Net.WebClient
$browser.Proxy.Credentials =[System.Net.CredentialCache]::DefaultNetworkCredentials 

$url = 'http://finance.yahoo.com/webservice/v1/symbols/allcurrencies/quote'
$xml = New-Object xml
$xml.Load($url)

[xml]$YahooDataDocument = $xml.InnerXml
$YahooDataDocument.List.resources.resource | format-table name,price

但是我无法按要求获取数据，我只得到：

Name     price
----     -----
resource      
resource      
resource      
resource      
resource      
.
.
..

Answer 1

试试这个：

$browser = New-Object System.Net.WebClient
$browser.Proxy.Credentials =[System.Net.CredentialCache]::DefaultNetworkCredentials 
$url = 'http://finance.yahoo.com/webservice/v1/symbols/allcurrencies/quote'
[xml]$xml = $browser.DownloadString($url)

$resultset = New-Object System.Collections.ArrayList
foreach ($quote in $xml.list.resources.resource){
    $singlequote = New-Object System.Collections.Specialized.OrderedDictionary
    foreach($element in $quote.field){
        $singlequote.Add($element.name,$element.'#text')
    }
    $resultset += New-Object PSObject -Property $singlequote
}
$resultset | format-table

事情是当你得到 $xml.list.resources.resource 时它变成 System.Array 所以你需要处理每个对象分开。
