我正在尝试验证以下 XML，但我无法验证，您能指出错误吗？

<!-- menu: its a menu -->
<menu id="Welcome">
    <!--audio: file to play -->
    <audio src="D:\Telephony\VOXs\Welcome.vox" />
</menu>

<!-- form: its a menu -->
<menu id="LanguageSelection">
    <audio src="D:\Telephony\VOXs\LanguageSelection.vox" />

    <input timeout="5" max_timeout="2" max_invalid_input="2" valid_dtmfs="1, 2">

        <!-- noinput: if timeout occurred, execute this -->
        <noinput>
            <audio src="D:\Telephony\VOXs\Timeout.vox" />
        </noinput>

        <!-- nomatch: if wrong dtmf given, following will execute -->
        <nomatch>
            <audio src="D:\Telephony\VOXs\InvalidInput.vox" />
        </nomatch>

        <switch>
            <dtmf-1>
                <audio src="D:\Telephony\VOXs\EnglishSelected.vox" />
            </dtmf-1>

            <dtmf-2>
                <audio src="D:\Telephony\VOXs\UrduSelected.vox" />
            </dtmf-2>
        </switch>
    </input>
</menu>

<menu id="MainMenu">
    <audio src="D:\Telephony\VOXs\MainMenu.vox" />

    <input timeout="5" max_timeout="2" max_invalid_input="2" valid_dtmfs="1, 2">

        <!-- noinput: if timeout occurred, execute this -->
        <noinput>
            <audio src="D:\Telephony\VOXs\Timeout.vox" />
        </noinput>

        <!-- nomatch: if wrong dtmf given, following will execute -->
        <nomatch>
            <audio src="D:\Telephony\VOXs\InvalidInput.vox"/>
        </nomatch>

        <switch>
            <dtmf-1>
                <goto menu="InformationMenu" />
            </dtmf-1>

            <dtmf-2>
                <goto menu="SupportMenu" />
            </dtmf-2>
        </switch>
    </input>
</menu>

我在使用 Validome.org 验证时收到以下错误.

错误:文档中跟在根元素之后的标记必须格式正确。

错误位置:menu id="LanguageSelection">

最佳答案

你有不止一个顶级元素<menu> .

尝试以下操作。我添加了 <MenuItems>作为顶级元素并在末尾将其关闭。

<MenuItems>
<!-- menu: its a menu -->
<menu id="Welcome">
    <!--audio: file to play -->
    <audio src="D:\Telephony\VOXs\Welcome.vox" />
</menu>

<!-- form: its a menu -->
<menu id="LanguageSelection">
    <audio src="D:\Telephony\VOXs\LanguageSelection.vox" />

    <input timeout="5" max_timeout="2" max_invalid_input="2" valid_dtmfs="1, 2">

        <!-- noinput: if timeout occurred, execute this -->
        <noinput>
                <audio src="D:\Telephony\VOXs\Timeout.vox" />
        </noinput>

        <!-- nomatch: if wrong dtmf given, following will execute -->
        <nomatch>
                <audio src="D:\Telephony\VOXs\InvalidInput.vox" />
        </nomatch>

        <switch>
                <dtmf-1>
                        <audio src="D:\Telephony\VOXs\EnglishSelected.vox" />
                </dtmf-1>

                <dtmf-2>
                        <audio src="D:\Telephony\VOXs\UrduSelected.vox" />
                </dtmf-2>
        </switch>
    </input>
</menu>

<menu id="MainMenu">
    <audio src="D:\Telephony\VOXs\MainMenu.vox" />

    <input timeout="5" max_timeout="2" max_invalid_input="2" valid_dtmfs="1, 2">

        <!-- noinput: if timeout occurred, execute this -->
        <noinput>
                <audio src="D:\Telephony\VOXs\Timeout.vox" />
        </noinput>

        <!-- nomatch: if wrong dtmf given, following will execute -->
        <nomatch>
                <audio src="D:\Telephony\VOXs\InvalidInput.vox"/>
        </nomatch>

        <switch>
                <dtmf-1>
                        <goto menu="InformationMenu" />
                </dtmf-1>

                <dtmf-2>
                        <goto menu="SupportMenu" />
                </dtmf-2>
        </switch>
    </input>
</menu>
</MenuItems>

您可以通过在 ie 中打开它来快速检查您的 xml。当我打开你的 xml 时，这就是我得到的。

Only one top level element is allowed in an XML document. Error processing resource 'file://Users/shoban/...

<menu id="LanguageSelection">
-^
