Access #text Property Of XMLAttribute In Powershell
Answer : Besides #text , you can also access XmlAttribute 's value via Value property : $attr = $xml.SelectSingleNode("//obj/indexlist/index[@name='DATE']/@value") #print old value $attr.Value #update attribute value $attr.Value = "new value" #print new value $attr.Value Note that Value in $attr.Value is property name of XmlAttribute . It doesn't affected by the fact that the attribute in your XML named value . Don't select the attribute, select the node. The attributes of the node will be represented as properties and can be modified as such: $node = $xml.SelectSingleNode("//obj/indexlist/index[@name='DATE']") $node.value = 'foo' Use a loop if you need to modify several nodes: $nodes = $xml.SelectNodes("//obj/indexlist/index[@name='DATE']") foreach ($node in $nodes) { $node.value = 'foo' }
