从搜索参数中过滤 XML

Question

我正在我正在创建的网站上创建一个小型搜索功能。我正在使用 Umbraco CMS，我需要搜索的所有节点都是正在搜索的页面的子节点。现在我有一个包含七个字段的搜索框。三个输入字段和四个下拉列表。

这是我需要从中查找结果的 XML：

<Modellist id="1073" parentID="1052" level="2" writerID="0" creatorID="0" nodeType="1065" template="1066" sortOrder="0" createDate="2010-07-12T20:23:35" updateDate="2010-07-12T21:25:13" nodeName="Piger-girls" urlName="piger-girls" writerName="Administrator" creatorName="Administrator" path="-1,1052,1073" isDoc="">

    <shoeSize>31-35</shoeSize>
</Model>

名为“size”、“eyeColor”、“hai​​rColor”和“shoeSize”的标签应与我的搜索框中的四个下拉列表相匹配。可以从名为名称的输入字段中搜索名为“标题”的标签。然后我有另一个名为“heightFrom”和“heightTo”的文本字段。在这里，用户可以搜索身高，这应该与名为“height”的 XML 标签相匹配。

我很容易说，如果名称字段不为空，我可以这样做：

<xsl:apply-templates select="$currentPage/*[@isDoc][contains(Exslt.ExsltStrings:lowercase(./title),$name)]">
                <xsl:sort data-type="text" select="title" order="ascending"/>
            </xsl:apply-templates>

$name 包含搜索到的名称。这将为我提供在“标题”标签中具有搜索名称的所有节点。但我该如何继续下去呢？当然，我可以创建一个选择，其中包含很多（超过 40 个）时间，但这将是一项艰巨的工作，并且将来很难维护。 困难的事情之一是没有一个字段是必填的，所以我不知道哪些字段将被填写。 我还能做点别的吗？

顺便说一句 - URL 可能如下所示： http://my.site/search.aspx?hf=150&ht=&size=62&ec=&hc=&ss=&name=Julie

我拥有所有七个变量的值如下：

<xsl:variable name="heightFrom" select="umbraco.library:Request('hf')"/>
<xsl:variable name="heightTo" select="umbraco.library:Request('ht')"/>
<xsl:variable name="size" select="umbraco.library:Request('size')"/>
<xsl:variable name="eyeColor" select="umbraco.library:Request('ec')"/>
<xsl:variable name="shoeSize" select="umbraco.library:Request('ss')"/>
<xsl:variable name="hairColor" select="umbraco.library:Request('hc')"/>
<xsl:variable name="name" select="Exslt.ExsltStrings:lowercase(umbraco.library:Request('name'))"/>

任何帮助和输入将不胜感激！

预先感谢:)

我认为您只需要在正确的上下文中使用 XPath 表达式。该样式表：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:param name="heightFrom" select="120"/>
    <xsl:param name="heightTo" select="130"/>
    <xsl:param name="size" />
    <xsl:param name="eyeColor" />
    <xsl:param name="shoeSize" />
    <xsl:param name="hairColor" />
    <xsl:param name="name" />
    <xsl:template match="/">
        <Modellist>
            <xsl:copy-of select="*/Model[height >= $heightFrom and $heightTo >= height
                              or
                             height >= $heightFrom and not($heightTo)
                              or
                             not($heightFrom) and $heightTo >= height]
                            [size = $size or not($size)]
                            [eyeColor = $eyeColor or not($eyeColor)]
                            [$shoeSize >= substring-before(shoeSize,'-')
                              and 
                             substring-after(shoeSize,'-') >= $shoeSize
                              or
                             not($shoeSize)]
                            [hairColor = $hairColor or not($hairColor)]
                            [title = $name or not($name)]"/>
        </Modellist>
    </xsl:template>
</xsl:stylesheet>

结果：

<Modellist>
    <Model id="1075" parentID="1073" level="3" writerID="0" creatorID="0" nodeType="1067" template="1068" sortOrder="1" createDate="2010-07-12T20:25:31" updateDate="2010-07-12T21:01:58" nodeName="Lene Madsen" urlName="lene-madsen" writerName="Administrator" creatorName="Administrator" path="-1,1052,1073,1075" isDoc="">
