问题描述：

我在创建的网站上创建小型搜索功能。我正在使用Umbraco CMS，并且我需要搜索的所有节点都是正在搜索的页面的子项。现在我有一个有七个字段的搜索框。三个输入字段和四个下拉菜单。从搜索参数过滤XML

这是我需要从找到我的结果的XML：

</Model>

所谓的“大小”的标签，“眼睛颜色”，“hairColor的”和“shoeSize”应与匹配我的搜索框中有四个下拉菜单。称为“标题”的标签可以从称为名称的输入字段中搜索。然后我有另一个名为“heightFrom”和“heightTo”的文本框。这里用户可以在高度上进行搜索，并且这应该与称为“高度”的XML标签匹配。

很容易的，我说，如果名称字段不为空，我可以只是这样做：

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

$名称中包含搜索姓名。这将给我所有在“标题” - 标签中具有搜索名称的节点。但是，我怎么从这里开始。当然，我可以创造一个选择，有很多（超过40个）时间，但这对于这个很重要，而且在将来很难保持。 其中一个难点是没有任何字段是强制性的，所以我不知道哪个字段会被填写。 我可以做其他事吗？

顺便说一句 - 一个URL可能例子是这样的： http://my.site/search.aspx?hf=150&ht=&size=62&ec=&hc=&ss=&name=Julie

我所有的值的七个变量是这样的：

<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'))"/>

任何帮助和投入将大大appreaciated ！

感谢提前:)

你能说我通情达理的你，如果我说你想匹配的变量条件的'Model'元素？ – 2010-07-13 23:23:34

是的，这是正确的。也许我没有这么好描述。但你是对的。我想要符合搜索标准的模型元素。如果你有提示或提示，只是这样说，它可能会导致我的方向正确:) - 谢谢。 – 2010-07-14 07:03:30

我想你只需要在正确的上下文中的XPath表达式。这styleshet：

<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="">
