Filter XML from searchparameters

Question

Hi there folks!

I'm creating a small search function on a site I'm creating. I'm working with Umbraco CMS, and all the nodes that I need to search are children of the page that are being searched on. Right now I have a search box with seven fields. three input fields and four dropdown's.

This is the XML that I need to find my results from:

<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="">

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

The tags called "size","eyeColor","hairColor" and "shoeSize" shall be matched with the four dropdowns in my search box. The tag called "title" can be searched from a input field called name. And then I have another to textfields called "heightFrom" and "heightTo". here a user can search on height, and this should be matched against the XML-tag called "height".

It's easy for me to say that if the name-field is not empty I can just do this:

<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 contains the searched name. And this will give me all the nodes that have the searched name in the "title"-tag. But how do I get on from this. Of course I can create a choose, with a lot (more than 40) of when's in it, but that would be a big job to that, and very difficult to maintain in the future. One of the difficult things are that none of the fields are mandatory, so I don't know which of the fields will be filled out. Can I do anything else?

By the way - a URL could in example look like this: http://my.site/search.aspx?hf=150&ht=&size=62&ec=&hc=&ss=&name=Julie

I have all of the values in seven variables like this:

<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'))"/>

Any help and inputs will be greatly appreaciated!

Thanks in advance :)

Sorry folks, but I have to bump this. As Alejandro asked, it's the "Model"-elements I need to show when a user have searched. -Thanks

I think you only need an XPath expression in the correct context. This styleshet:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"&gt;
    <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>

Result:
