xml - 将现有 XML 文件中的节点附加到新的 XML 文档中
问题描述
我目前正在为我正在使用的一些 XML 文件开发版本控制功能。基本工作流程是，在解析 XML 文件时，将其按 Order 分解，然后放入数据库表中，然后根据最新版本的 XML 提取并重新组合成我可以使用的对象。
这是一个订单看起来像 XML 的示例（您可以略过这个 - 这正是我正在使用的）：

现在，一个典型的订单包含大约 60 个这样的部分。长话短说，我需要从这些部分中重新组合 XML。
到目前为止，我已经创建了 xml 对象并创建了第一个节点（这些只是该文件中的一个），它是一个 VendorInvoice。
# new xml
[xml]$Newxml = New-Object System.Xml.XmlDocument
$newxml.LoadXml("<?xml version=`"1.0`" encoding=`"us-ascii`"?><VendorInvoices></VendorInvoices>")
我需要将这些订单中的每一个附加到 VendorInvoice 到 VendorInvoice 节点，我在这里尝试这样做：
foreach($VendorInvoice in $xml.VendorInvoices)
{
foreach($Order in $VendorInvoices.Order)
{
$newxml.AppendChild($Order.OuterXml)
$newxml.Save($Newxml)
}
}
但是，这样做似乎不会在 VendorInvoices 节点下填充任何内容：
xml VendorInvoices
--- --------------
version="1.0" encoding="us-ascii"
有谁知道我要去哪里错了？这个过程需要我从 XML 文件中删除大量内容，但这是我必须构建 XML 文件的第一个实例。
如果需要，我可以提供更多信息。
解决方案
这是一个简化输入的工作示例：
# The input document.
[xml] $xml = @'
<VendorInvoices>
<Order>
<OrderNum>1</OrderNum>
</Order>
<Order>
<OrderNum>2</OrderNum>
</Order>
</VendorInvoices>
'@
# Create the target XML document.
# Add a <dummy /> child element to <VendorVoices>, so we
# can get a reference to child element <VendorVoices> with dot notation below.
[xml] $newXml = @'
<?xml version="1.0" encoding="us-ascii"?>
<VendorInvoices><dummy/></VendorInvoices>
'@
# Get a referene to the new document's <VendorInvoices> element.
$newVendorInvoices = $newXml.VendorInvoices
$newVendorInvoices.Removeall() # Remove the dummy child node.
# Loop over all <Order> child elements of the original document's
# <VendorInvoices> element and add them to the target document's
# <VendorInvoices> element.
foreach ($order in $xml.VendorInvoices.Order) {
# Import the order at hand into the new document and append it to the
# <VendorInvoices> element. Note: .AppendChild() modifies the document in-place
# and *also returns* the new child node; we assign to $null to suppress this output.
$null = $newVendorInvoices.AppendChild($newXml.ImportNode($order, $true))
}
# Use Format-Custom to print a quick-and-dirty visualization of the document.
# If you want to save the document to a new file, use, e.g., $newXml.Save("$PWD/new.xml")
$newXml | Format-Custom
以上产生：
class XmlDocument
{
xml = version="1.0" encoding="us-ascii"
VendorInvoices =
class XmlElement
{
Order =
[
class XmlElement
{
OrderNum = 1
}
class XmlElement
{
OrderNum = 2
}
]
}
}
至于你尝试了什么：
您的内部循环有一个错字：
$VendorInvoices应该是$VendorInvoice.您错误地尝试附加
$Order到目标文档的根（文档）元素而不是子元素<VendorInvoices>。使用- 期望实例 - 将现有元素的
.OuterXml属性值 - a -附加到不同的元素不起作用。[string].AppendChild()[System.Xml.XmlNode]$newXml.Save($newXml)毫无意义：内存中的DOM 操作不需要保存操作，如果要保存到文件，则必须指定输出文件路径；事实上，它的字符串化$newXml- 这是字符串文字'System.Xml.XmlDocument'- 在这里被解释为输出文件名。
