Including some records and excluding others
 
I'm trying to learn how/do two things here:
1) If the user searches for "Data" ($searchtext = "Data") the output should also include the fourth record because Field1 contains "all".
 2) But the output of this same search should also exclude any records where Field1 contains "info" ($searchtext = "info"). You can see by the textsearch template that I have 3 case conversion variables that can be used to to include/exclude "All", "all", "ALL", "Info", "info", or "INFO"

A statement like this includes "all" but I can't figure out how to get it to also exclude "info" or use my case variables:
 <xsl:for-each select="record[*[name() = $searchfield][contains(., $ProperText) or contains(., $UCASETEXT) or contains(., $lcasetext) or ../Field1[contains(., 'ALL') or contains(., 'all') or contains(., 'All')]]]">

XML Data

    <Field2>Data6-2</Field2>
    <dtmField>2008-01-28T06:06:00Z</dtmField>

Record 2 is excluded because "Field1" = Info
  <record>
    <Field1>Data3-1</Field1>
    <Field2>Data3-2</Field2>
    <dtmField>2008-01-28T03:03:00Z</dtmField>

  </record>
  <record>

    <Field2>Data5-2</Field2>
    <dtmField>2008-01-28T05:05:00Z</dtmField>
  </record>
Record 6 is excluded because "Field1" = info (notice the case is different)
</data>

Unfortunately in XSLT 1.0 the easiest way to check things while ignoring case is to use the translate() function.

e.g. translate(., "ABCDEFGHIJKLMNOPQRSTUVWXYZ", "abcdefghijklmnopqrstuvwxyz") will convert the current text to lower case.

In XSLT 2.0 you can use the lower-case() function.

<xsl:template name="textsearch">
    <xsl:variable name="data">
      <xsl:value-of select="translate($searchdata, "ABCDEFGHIJKLMNOPQRSTUVWXYZ", "abcdefghijklmnopqrstuvwxyz")"/>
    </xsl:variable>
    <xsl:for-each select="record[*[name() = $searchfield and contains(translate(., "ABCDEFGHIJKLMNOPQRSTUVWXYZ", "abcdefghijklmnopqrstuvwxyz"), $data)]]">
      <xsl:sort select="*[name()=$sortbyfield]" order="{$sortorder}"/>
      <xsl:call-template name="resulttable"/>
    </xsl:for-each>
  </xsl:template>

Thanks for your response Sam but after getting some much needed rest over the weekend and after looking over my question again I realized that I misworded my question. I'll re-ask it under the topic "Excluding certain records from a search".

Thanks,
Russ Lewis
