用xslt构建django模板文件

Question

我有大约4,000个html文档,我试图使用xslt转换为django模板.我遇到的问题是,当我尝试在属性标记中包含模板变量时,xslt正在转义模板变量的'{'花括号; 我的xslt文件如下所示:

<xsl:template match="p">
    <p>
        <xsl:attribute name="nid"><xsl:value-of select="$node_id"/></xsl:attribute>
        <xsl:apply-templates select="*|node()"/>
    </p>
    <span>
        {% get_comment_count for thing '<xsl:value-of select="$node_id"/>' as node_count %}
        <a href="">{{ node_count }}</a> //This works as expected
    </span>
    <div>
        <xsl:attribute name="class">HControl</xsl:attribute>
        <xsl:text disable-output-escaping="yes">{% if node_count > 0 %}</xsl:text> // have to escape this because of the '>'
        <div class="comment-list">
            {% get_comment_list for thing '<xsl:value-of select="$node_id"/>' as node_comments %}
            {% for comment in node_comments %}
            <div class="comment {{ comment.object_id }}"> // this gets escaped
                <a>
                <xsl:attribute name="name">c{{ comment.id }}</xsl:attribute> //and so does this
                </a>
                <a>
                <xsl:attribute name="href">
                {% get_comment_permalink comment %}
                </xsl:attribute>
                permalink for comment #{{ forloop.counter }}
                </a>
                <div>
                {{ comment.comment }}
                </div>
            </div>
            {% endfor %}
        </div>
        {% endif %}
    </div>

输出看起来像这样:

<div>
<p nid="50:1r:SB:1101S:5">
    <span class="Insert">B.  A person who violates this section is guilty of a class 1 misdemeanor.</span>
</p>
<span>
    <a href="">1</a>
</span>
<div class="HControl">
    <div class="comment-list">
        <div class="comment '{ comment.object_id }'"> // this should be class="comment #c123"
            <a name="c%7B%7B%20comment.id%20%7D%7D"></a> // this should name="c123"
            <a href="%7B%%20get_comment_permalink%20comment%20%%7D"> //this should be an href to the comment
                permalink for comment #1
            </a>
            <div>
                Well you should show some respect!
            </div>
        </div>
    </div>
</div>

我用lxml.etree转换文件,然后将字符串传递给django模板对象,然后渲染它.我似乎不明白如何让xslt解析器单独留下花括号

Answer 1

XSLT有自己的花括号用途 - 它们用于属性值模板,如下所示:

<!-- $someVariableOrExpression will be evaluated here -->
<div title="{$someVariableOrExpression}" />

要获得字面花括号到XSLT属性值,你需要逃避他们,这是他们加倍完成:

<!-- the title will be "{$someVariableOrExpression}" here -->
<div title="{{$someVariableOrExpression}}" />

所以如果你想输出文字双花括号,你需要(猜猜是什么):

<div title="{{{{$someVariableOrExpression}}}}" />
