Hi, I have an interesting problem in a macro wherein I am building a search filter for use with ucomponents.xml:FilterNodes().

The filter variable I am bulding works great with the dropdowns but when I am searching properties for a text string, my routine will only return lettercase matches. I am familiar with using the Exslt.ExsltStrings:lowercase() method, but because of how I am building this string using the concat function, I can force the original string to a given case but can't figure out how to do it on the property values with which I am comparing it inside the concat(). Here is the code (look for the "case-insensitve" comments):

<xsl:variable name="filter">
  <xsl:if test="normalize-space($contains)">
    <xsl:variable name="containsString">
      <xsl:text>"xsl:text>
      CASE-INSENSITIVE
      <xsl:value-of select="$contains"/>
      <xsl:text>"xsl:text>
    xsl:variable>
    CASE-INSENSITIVE
    <xsl:value-of select="
        concat('[contains(@nodeName, ', $containsString, ')
        or contains(resourceDescription, ', $containsString, ')
        or contains(mediaType, ', $containsString, ')
        ]')" />
  xsl:if>
  <xsl:if test="normalize-space($type)">
    <xsl:variable name="mediaTypeString">
      <xsl:text>"xsl:text>
      <xsl:value-of select="umbraco.library:GetPreValueAsString($type)"/>
      <xsl:text>"xsl:text>
    xsl:variable>
    <xsl:value-of select="concat('[mediaType = ', $mediaTypeString, ']')" />
  xsl:if>
  <xsl:if test="normalize-space($usecase)">
    <xsl:value-of select="concat('[resourceUseCases//nodeId = ', $usecase, ']')" />         
  xsl:if>
  <xsl:if test="normalize-space($industry)">
    <xsl:value-of select="concat('[resourceIndustries//nodeId = ', $industry, ']')" />              
  xsl:if>
  <xsl:if test="normalize-space($product)">
    <xsl:value-of select="concat('[resourceProducts//nodeId = ', $product, ']')" />         
  xsl:if>
  <xsl:if test="not(normalize-space(concat($contains, $type, $usecase, $industry, $product)))">
    <xsl:text>[true()]xsl:text>
  xsl:if>
xsl:variable>


<xsl:variable name="filteredResources">
  <xsl:choose>
    <xsl:when test="normalize-space(concat($contains, $type, $usecase, $industry, $product))">
      <root>
        <xsl:copy-of select="ucomponents.xml:FilterNodes($currentPage, concat('
          ancestor-or-self::Home[@isDoc]//Resources[1][@isDoc]/ResourceType
          [@isDoc][not(umbracoNaviHide=1)]//*
          [@isDoc][not(umbracoNaviHide=1)]
          [(name()="LeadProtectedFile" and normalize-space(resourceFile))
          or
          (name()="LeadProtectedVideo" and normalize-space(embedCode))]',
          $filter))"/>
      root>
    xsl:when>
    <xsl:otherwise>
      <root>
        <xsl:copy-of select="$currentPage/ancestor-or-self::Home[@isDoc]//Resources[1]/ResourceType
          [@isDoc][not(umbracoNaviHide=1)]//*
          [@isDoc][not(umbracoNaviHide=1)]
          [(name()="LeadProtectedFile" and normalize-space(resourceFile))
          or
          (name()="LeadProtectedVideo" and normalize-space(embedCode))]"/>
      root>
    xsl:otherwise>
  xsl:choose>  
xsl:variable>

I have struggled mightily with this -- just don't know how I can call a function inside the concat with all of the single and double quotes already going on, it's confusing me!

Thanks in advance,

Garrett
