Xml 使用PowerShell从manifest.xsf文件提取数据

我正在尝试提取有关应用于许多InfoPath表单的规则的信息，我正在使用Powershell进行此操作

我已经解包了

template.xsn

文件，找到了存储此数据的

manifest.xsf

文件

使用Powershell

[xml]$ProjectXmlFile=Get Content manifest.xsf

获取xml数据，我正在努力正确识别节点

使用“

xsf:

”前体标识节点，例如：

<xsf:submit caption="Submit" disableMenuItem="no" onAfterSubmit="close" showStatusDialog="no">
    <xsf:errorMessage>The form cannot be submitted because of an error.</xsf:errorMessage>
    <xsf:davAdapter name="SharePoint Library Submit" submitAllowed="yes" overwriteAllowed="no">
        <xsf:folderURL value="../"></xsf:folderURL>
        <xsf:fileName value="my:Submit/my:ref" valueType="expression"></xsf:fileName>
    </xsf:davAdapter>
</xsf:submit>

或者我无法访问这些节点还有其他原因吗？

通过将属性设置为

$false

值，可以禁用命名空间支持

$x = @'
<xsf:submit caption="Submit" disableMenuItem="no" onAfterSubmit="close" showStatusDialog="no">
    <xsf:errorMessage>The form cannot be submitted because of an error.</xsf:errorMessage>
    <xsf:davAdapter name="SharePoint Library Submit" submitAllowed="yes" overwriteAllowed="no">
        <xsf:folderURL value="../"></xsf:folderURL>
        <xsf:fileName value="my:Submit/my:ref" valueType="expression"></xsf:fileName>
    </xsf:davAdapter>
</xsf:submit>
'@
$xml = New-Object -TypeName System.Xml.XmlDocument
$sr = New-Object -TypeName System.IO.StringReader $x
$xtr = New-Object -TypeName System.Xml.XmlTextReader $sr
$xtr.Namespaces = $false
$xml.Load($xtr)
$xml.'xsf:submit'.'xsf:errorMessage'

通过将属性设置为

$false

值，可以禁用命名空间支持

$x = @'
<xsf:submit caption="Submit" disableMenuItem="no" onAfterSubmit="close" showStatusDialog="no">
    <xsf:errorMessage>The form cannot be submitted because of an error.</xsf:errorMessage>

'@
$xml = New-Object -TypeName System.Xml.XmlDocument
$sr = New-Object -TypeName System.IO.StringReader $x
$xtr = New-Object -TypeName System.Xml.XmlTextReader $sr
$xtr.Namespaces = $false
$xml.Load($xtr)
$xml.'xsf:submit'.'xsf:errorMessage'

The form cannot be submitted because of an error.
