问题描述
我有一个 xml 文档,我想使用 powershell 脚本生成它,如下所示:
I have an xml document which is as below that I want to generate using powershell script:
<?xml version="1.0" encoding="utf-8"?>
<?mso-infoPathSolution name="urn:schemas-microsoft-com:office:infopath:JansenTRAM:-myXSD-2013-06-27T10-48-27" solutionVersion="0.0.0.1471" productVersion="15.0.0.0" PIVersion="1.0.0.0" href="http:xxx"?>
<?mso-application progid="InfoPath.Document" versionProgid="InfoPath.Document.4"?>
<?mso-infoPath-file-attachment-present?>
<my:TemplateFields xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:pc="http://schemas.microsoft.com/office/infopath/2007/PartnerControls" >
.....
.....
</my:TemplateFields>
我要生成的脚本是:
$filePath= "C:\Powershell\Report.xml"
if(Test-Path $filePath)
{
Remove-Item $filePath
}
#set encoding
$encoding = [System.Text.Encoding]::UTF8
# Create The Document
$XmlWriter = New-Object System.XMl.XmlTextWriter($filePath,$encoding)
# Set The Formatting
$xmlWriter.Formatting = "Indented"
$xmlWriter.Indentation = "4"
# Write the XML Decleration
$xmlWriter.WriteStartDocument()
#SetNamespace($XmlWriter)
# Write Root Element
$xmlWriter.WriteStartElement($RootElement)
$XmlWriter.WriteAttributeString("xmlns","xsi", $null, "http://www.w3.org/2001/XMLSchema-instance")
#$xmlWriter.WriteEndElement # <-- Closing Servers
# $XmlWriter.
# Write Close Tag for Root Element
$xmlWriter.WriteEndElement # <-- Closing RootElement
# End the XML Document
$xmlWriter.WriteEndDocument()
# Finish The Document
$xmlWriter.Finalize
$xmlWriter.Flush
$xmlWriter.Close()
我在 $XmlWriter.WriteAttributeString("xmlns","xsi", $null, "http://www.w3.org/2001/XMLSchema-instance") 行上遇到错误
code> 指定:'xmlns' 属性绑定到保留的命名空间 'http://www.w3.org/2000/xmlns/
I am getting an error on the line $XmlWriter.WriteAttributeString("xmlns","xsi", $null, "http://www.w3.org/2001/XMLSchema-instance")
specifying : The 'xmlns' attribute is bound to the reserved namespace 'http://www.w3.org/2000/xmlns/
我该怎么办?
推荐答案
传递 xmlns 命名空间而不是 $null
:
Pass the xmlns namespace instead of $null
:
$XmlWriter.WriteAttributeString("xmlns", "xsi",
"http://www.w3.org/2000/xmlns/",
"http://www.w3.org/2001/XMLSchema-instance");
