How can I search for a varying string in an XML file using VBS and replace it with another string

<A>randomstuff</A>

<A></A>

<?xml version="1.0" encoding="UTF-8"?>

Set xml = CreateObject("Msxml2.DOMDocument.6.0")
xml.Load "C:doc.xml"
Set password = xml.SelectSingleNode("//root/element/password")
password.Text = "Hello, world"
xml.Save "C:doc.xml"

<root>
    <element>
        <password>Example password</password>
    </element>
</root>

<?xml version="1.0" encoding="UTF-8"?>

<container name="root">

Set xml = CreateObject("Msxml2.DOMDocument.6.0")
xml.Load "config.xml"
Set password = xml.SelectSingleNode("//root/EIMServer/Global/OldConfig/K2097153")
wscript.echo password.text
