Answer 1

string-length($varname) will tell you the length of a variable containing data that can be interpreted as a string.

Answer 2

In XPath 1.0:

string-length($title) = 12

Take notice that diacritical marks also would be counted.

In XPath 2.0 you cuold use:

string-length(normalize-unicode($title)) = 12

Answer 3

Use:

 <xsl:if test="string-length($Title) = 12">
   <!-- Your code here -->
 </xsl:if>

Answer 4

Alternatively you can do the equivalent to and if/else statement in XSL:

<xsl:choose>
  <xsl:when test="string-length($Title) = 12">
    <!-- code when the check is true -->
  </xsl:when>
  <xsl:otherwise>
    <!-- code when it's false -->
  </xsl:otherwise>
</xsl:choose>
