xslt、javascript 和未转义的 html 实体 [英] xslt, javascript and unescaped html entities

问题描述

我对 xslt、js 和 html 实体有一个小问题，例如.在模板中:

i have a tiny little problem with xslt, js and html entities, eg. within a template:

<script type="text/javascript">
    <xsl:value-of select="/some/node"/>
    for (var i = 0; i &lt; 5; i++) {
        //            ^^^ js error
    }
</script>

<script type="text/javascript">
    <xsl:value-of select="/some/node"/>
    for (var i = 0; i < 5; i++) {
        //            ^ xslt error
    }
</script>

<script type="text/javascript">
    <xsl:value-of select="/some/node"/>
    // <![CDATA[
    for (var i = 0; i < 5; i++) {
        //            ^ becomes &lt;
    }
    // ]]>
</script>


<script type="text/javascript">
    <xsl:value-of select="/some/node"/>
    for (var i = 0; i <xsl:value-of disable-output-escaping="yes" select="string('&lt;')"/> 5; i++) {
        // works of course
    }
</script>

有谁知道我的问题可能来自哪里?我一直认为 xslt 处理器会留下 <script/> 的内容.使用 html 输出方法时未转义的元素 ...

does anyone have an idea where my problem could come from? i always thought the xslt processor would leave the content of a <script/> element unescaped when using the html output method ...

我在使用 macportsports 安装的 OSX 上运行 libxslt2 版本 1.1.24 ...

i run libxslt2 version 1.1.24 on OSX which was installed using macportsports ...

推荐答案

ok.长话短说:

似乎在某些 libxslt 版本中，xslt 处理器在使用 html 输出方法时将 <script/> 元素的内容保留为未转义，对于其他版本不是 ...因此建议如下:

it seems that with some libxslt versions the xslt processor leaves the content of a <script/> element unescaped when using the html output method, with others not ... therefore the following is recommended:

<script type="text/javascript">
    <xsl:value-of select="/some/node"/>
    <xsl:text disable-output-escaping="yes">
        // ^ does the trick ...
        for (var i = 0; i < 5; i++) {
            //            ^ works
        }
    </xsl:text>
</script>
