Parameters

The following table describes the parameters of the XmlPoke task.

Parameter Description
Namespaces Optional String parameter.

Query Optional String parameter.

Specifies the XPath query.
Value Required ITaskItem parameter.

XmlInputPath Optional ITaskItem parameter.

Remarks

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.
