我正在尝试使用Powershell向web.config中的sectionGroup
元素添加configuration/configSections
元素。
我目前有
$filePath = [path to my web.config file]
# load the XML from the web.config
$xml = New-Object XML
$xml = [xml](Get-Content $filePath)
# navigate to the <configSections> element
$xmlConfigSections = $xml.SelectSingleNode("//configuration/configSections")
# create the new <sectionGroup> element with a 'name' attribute
$sectionGroup = $xml.CreateElement("sectionGroup")
$xmlAttr = $xml.CreateAttribute("name")
$xmlAttr.Value = "myCustomSectionGroup"
$sectionGroup.Attributes.Append($xmlAttr)
# now add the new <sectionGroup> element to the <configSections> element
$xmlConfigSections.AppendChild($sectionGroup)
#save the web.config
$xml.Save($filePath)
但这会导致CreateElement
方法出现异常:
“无法插入指定的节点作为此的有效子节点 node,因为指定的节点类型错误。“
我不明白为什么当我尝试创建元素时抛出这样的异常(异常似乎与附加元素有关)。
我尝试过的其他东西是
$newConfig = [xml]@'<sectionGroup name="myCustomSectionGroup"></sectionGroup>'@
$filePath = [path to my web.config file]
# load the XML from the web.config
$xml = New-Object XML
$xml = [xml](Get-Content $filePath)
# navigate to the <configSections> element
$xmlConfigSections = $xml.SelectSingleNode("//configuration/configSections")
$xmlConfigSections.AppendChild($newConfig)
但这会抛出与以前完全相同的异常。
<sectionGroup>
绝对是<configSections>
的有效孩子。
理想情况下,我更喜欢第二次尝试是否有效,因为这不需要我声明每个元素,每个属性,等。
有人可以向我解释为什么<configSections>
节点不允许我的<sectionGroup>
元素吗?
答案 0 :(得分:6)
这应该这样做:
$filePath = [path to my web.config file]
# load the XML from the web.config
$xml = New-Object XML
$xml = [xml](Get-Content $filePath)
$sectionGroup = $xml.CreateElement('sectionGroup')
$sectionGroup.SetAttribute('name','myCustomSectionGroup')
$sectionGroupChild = $xml.CreateElement('sectionGroupChild')
$sectionGroupChild.SetAttribute('name','myCustomSectionGroup')
$newNode = $xml.configuration.configSections.AppendChild($sectionGroup)
$newNode.AppendChild($sectionGroupChild)
$xml.Save($filePath)
