我有一个XML文档,我正在循环并在文件存在时下载并将其保存到磁盘。 我想更新XML文件以包含我保存数据的位置。我怎样才能做到最好?
XML文件示例:
<Invoices xmlns="http://example.com/">
<invoice>
<ContractorName>TEST contractor</ContractorName>
<Invoice_Number>12345</Invoice_Number>
<Invoice_Date>2017-05-20</Invoice_Date>
<Invoice_Amount>100.00</Invoice_Amount>
<Invoice_Hyperlink>https://example.com/path/files/file.pdf</Invoice_Hyperlink>
</invoice>
<invoice>
<ContractorName>TEST contractor 2</ContractorName>
<Invoice_Number>98765</Invoice_Number>
<Invoice_Date>2017-05-20</Invoice_Date>
<Invoice_Amount>1000.00</Invoice_Amount>
</invoice>
</invoices>
我的脚本如下所示,用于循环遍历XML数据并在本地保存文件。
$Invoicesfile = "D:\Download\invoices.xml"
[xml]$Invoice = Get-Content $Invoicesfile -Raw
$InvoiceDestinationDir = "D:\Invoices_Downloaded\"
foreach ($r in $Invoice.Invoices.invoice)
{
If($r.Invoice_Hyperlink -ne $null){
$Directory = $InvoiceDestinationDir + $r.ContractorName + "\"+ $InvoiceDate.ToString('yyyy') + "\" + $InvoiceDate.ToString('MM-MMM') + "\" + $InvoiceDate.ToString('dd')
#Test if destination directory exists and create it if it doesn't
if (!(Test-Path $Directory))
{
New-Item $Directory -type directory | Out-Null
}
#set destination to destination directory and files name consisting of Jobcode,
$destination = $Directory +"\"+ $r.Invoice_Number +"_" + $r.Invoice_Date + $r.Invoice_Hyperlink.SubString($r.Invoice_Hyperlink.LastIndexOf('.'))
Invoke-WebRequest -Uri $r.Invoice_Hyperlink -OutFile $destination
}
}
我发现的所有示例似乎都在使用CreateElement
下面的示例,但是我无法使其工作,因为上面示例中的$r
是System.Xml.XmlLinkedNode
和{ {1}}似乎仅适用于CreateElemnt
,System.Xml.XmlNode
但我希望该元素位于$Inovices
$Invoice.Invoices.invoice
任何建议都会受到赞赏。我要寻找的结果是用以下内容保存上述文件。
[xml] $doc = Get-Content($filePath)
$child = $doc.CreateElement("newElement")
$doc.DocumentElement.AppendChild($child)
答案 0 :(得分:0)
您找到的代码段工作正常。
$Invoice.Invoices.Invoice
是一个包含XmlLinkedNodes
在foreach循环前使用CreateElement()
和$Invoice
。
$Invoicesfile = "D:\Download\invoices.xml"
[xml]$Invoice = Get-Content $Invoicesfile -Raw
$InvoiceDestinationDir = "D:\Invoices_Downloaded\"
$child = $Invoice.CreateElement("Local_File")
foreach ($r in $Invoice.Invoices.Invoice){...}
在您的foreach中,您可以将$child
附加到您实际工作的节点
If($r.Invoice_Hyperlink -ne $null){
$r.appendchild($child)
$InvoiceDate = [datetime]::ParseExact($r.Invoice_Date, 'yyyy-MM-dd', $null)
如您所见,我从您的xml中解析了日期,以便能够使用$InvoiceDate.ToString()
- 方法
构建$destination
- 路径后,您可以使用$r.Local_File = $destination
