In addition to having the parameters that are listed in the table, this task inherits parameters from the TaskExtension class, which itself inherits from the Task class. For a list of these additional parameters and their descriptions, see TaskExtension base class.

Example

Here is a sample.xml to modify:

<Package xmlns="http://schemas.microsoft.com/appx/manifest/foundation/windows10"
         xmlns:mp="http://schemas.microsoft.com/appx/2014/phone/manifest"
         xmlns:uap="http://schemas.microsoft.com/appx/manifest/uap/windows10" >
<Identity Name="Sample.Product " Publisher="CN=1234" Version="1.0.0.0" />
<mp:PhoneIdentity PhoneProductId="456" PhonePublisherId="0" />
</Package>

In this example, if you want to modify /Package/mp:PhoneIdentity/PhoneProductId, then use

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <Namespace>
        <Namespace Prefix="dn" Uri="http://schemas.microsoft.com/appx/manifest/foundation/windows10" />
        <Namespace Prefix="mp" Uri="http://schemas.microsoft.com/appx/2014/phone/manifest" />
        <Namespace Prefix="uap" Uri="http://schemas.microsoft.com/appx/manifest/uap/windows10" />
    </Namespace>
</PropertyGroup>

<Target Name="Poke">
  <XmlPoke
    XmlInputPath="Sample.xml"
    Value="MyId"
    Query="/dn:Package/mp:PhoneIdentity/@PhoneProductId"
    Namespaces="$(Namespace)"/>
</Target>
</Project>

dn is here used as an artificial namespace prefix for default namespace.
