如何解决如何解码这个php文件

我想解码这段 PHP 代码。我不知道它是什么，除了它是某种代码。有人能帮助我吗？ 一个编译器：

<Grid>
    <Grid.RowDeFinitions>
        <RowDeFinition Height="Auto" />
        <RowDeFinition Height="Auto" />
        <RowDeFinition Height="*" />
    </Grid.RowDeFinitions>
    <Image Source="waterfront.jpg" />
    <Label Grid.Row="1" Text="this is test" />
    <Grid Grid.Row="2">
        <xct:TabView
            TabContentBackgroundColor="Yellow"
            TabIndicatorColor="Yellow"
            TabStripBackgroundColor="Blue"
            TabStripHeight="60"
            TabStripPlacement="Bottom">

            <xct:TabViewItem
                FontSize="12"
                Icon="triangle.png"
                Text="Tab 1"
                TextColor="White"
                TextColorSelected="Yellow">
                <ScrollView>
                    <StackLayout BackgroundColor="Gray">

                        <Label
                            HorizontalOptions="Center"
                            Text="TabContent1"

                        <Image  Source="waterfront.jpg" />
                        <Image  Source="internet.png" />
                    </StackLayout>
                </ScrollView>
            </xct:TabViewItem>

            <xct:TabViewItem

                TextColor="White"
                TextColorSelected="Yellow">
                <Grid>
                    <Label
                        HorizontalOptions="Center"
                        Text="TabContent2"
                        VerticalOptions="Center" />
                </Grid>
            </xct:TabViewItem>
        </xct:TabView>

</Grid>
