regex - YouTube网址-正则表达式

Question

我的反卫星策略文件中有以下配置:

旧的YouTube对象:

<object width="1280" height="720">
<param 
    name="movie" 
    value="http://www.youtube.com/v/Hl-zzrqQoSE
           ?version=3
           &amp;hl=en_US
           &amp;rel=0">
</param>
<param name="allowFullScreen" value="true">
</param>
<param name="allowscriptaccess" value="always">
</param>
<embed src="http://www.youtube.com/v/Hl-zzrqQoSE
            ?version=3
            &amp;hl=en_US
            &amp;rel=0" 
       type="application/x-shockwave-flash" 
       width="1280" 
       height="720" 
       allowscriptaccess="always" 
       allowfullscreen="true">
 </embed>
 </object>

AntiSamy配置:

 <common-regexps>
     <regexp name="YouTubeURL" value="(\s)*(http(s?)://)www.youtube.com/v/[\p{L}\p{N}]+[\p{L}\p{N}\p{Zs}\.\#@\$%\+&amp;;:\-_~,\?=/!]*(\s)*"/>
 ....

<!-- Tags related to YouTube -->
<tag name="object" action="validate">
<attribute name="height"/>
<attribute name="width"/>
<attribute name="type">
    <literal-list>
        <literal value="application/x-shockwave-flash"/>
    </literal-list>
</attribute>
<attribute name="data">
    <regexp-list>
        <regexp name="YouTubeURL"/>
    </regexp-list>
</attribute>
</tag>
<tag name="embed" action="validate">
<attribute name="height"/>
<attribute name="width"/>
<attribute name="type">
    <literal-list>
        <literal value="application/x-shockwave-flash"/>
    </literal-list>
</attribute>
<attribute name="allowfullscreen">
    <regexp-list>
        <regexp name="boolean"/>
    </regexp-list>
</attribute>
<attribute name="allowscriptaccess">
    <literal-list>
        <literal value="always"/>
    </literal-list>
</attribute>
<attribute name="src">
    <regexp-list>
        <regexp name="YouTubeURL"/>
    </regexp-list>
</attribute>
<attribute name="movie">
    <regexp-list>
        <regexp name="YouTubeURL"/>
    </regexp-list>
</attribute>
</tag>

目前，我在iframe上的配置:

    <!-- Frame & related tags -->

    <tag name="iframe" action="remove"/>
    <tag name="frameset" action="remove"/>
    <tag name="frame" action="remove"/>

新的YouTube iframe:

<iframe 
    width="1280" 
    height="720" 
    <!--   src="https://www.youtube-nocookie.com/embed/Hl-zzrqQoSE"  -->
    src="https://www.youtube.com/embed/Hl-zzrqQoSE" 
    frameborder="0" 
    allowfullscreen>
</iframe>

我认为iframe的代码应如下所示:

<tag name="iframe" action="validate">
        <attribute name="height"/>
        <attribute name="width"/>
        <attribute name="frameborder"/>
        <attribute name="src">
            <regexp-list>
                <regexp name="YouTubeURL"/>
            </regexp-list>
        </attribute>

        <attribute name="allowfullscreen">
            <regexp-list>
                <regexp name="boolean"/>
            </regexp-list>
        </attribute>
</tag>

您如何更改正则表达式，使其接受旧的和新的链接，例如:

    https://www.youtube-nocookie.com/embed/Hl-zzrqQoSE
    https://www.youtube.com/embed/Hl-zzrqQoSE
    https://www.youtube.com/v/Hl-zzrqQoSE
    http://www.youtube-nocookie.com/v/Hl-zzrqQoSE?version=3&hl=en_US&rel=0
    http://www.youtube.com/v/Hl-zzrqQoSE?version=3&hl=en_US&rel=0"

Answer 1

\s*(https?://)www.youtube(-nocookie)?.com/(?:v|embed)/[\p{L}\p{N}]+[\p{L}\p{N}\p{Zs}.#@$%+&;:_~,?=!/-]*\s*

我自由删除了不必要的捕获组，转义符和角色。
虽然我个人会使用类似的方法:

\s*(https?://www.youtube(?:-nocookie)?.com/(?:v|embed)/([a-zA-Z0-9-]+).*)

这会将整个youtube URL放入匹配组0，将视频ID放入匹配组1。
当youtube的URL不包含unicode字符时，使用unicode属性也不是很有意义。
