_If your <body> element just contains text, the following templates will transform it and escape any apostrophes present, replacing them with
' character entities:

<xsl:template match="body">
	<xsl:text>&lt;body&gt;</xsl:text>
	<xsl:call-template name="escape-apos">
		<xsl:with-param name="text" select="."/>
	</xsl:call-template>
	<xsl:text>&lt;/body&gt;</xsl:text>
</xsl:template>

<xsl:template name="escape-apos">
<xsl:param name="text"/>
<xsl:variable name="apos">'</xsl:variable>
 <xsl:choose>
  <xsl:when test="contains($text, $apos)">
   <xsl:value-of select="substring-before($text, $apos)"/>
   <xsl:text disable-output-escaping="yes">&amp;apos;</xsl:text>
   <xsl:call-template name="escape-apos">
    <xsl:with-param name="text" select="substring-after($text, $apos)"/>
   </xsl:call-template>
 </xsl:when>
 <xsl:otherwise>

xsl_

Match everything and apply all templates

<xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()" />
    </xsl:copy>
  </xsl:template>

_Define a variable

<xsl:variable name="name" select="expression">
<!-- Content:template -->
</xsl:variable>

_
Request paramteres in xsl

The "best" way (easier) is to use :

<xsl:param name="my_req_param" />

at the beginning of your xsl, then use it like a variable.

And in the sitemap, add to the xslt <map:transform ...> :

<map:transform ...>
<map:parameter name="use-request-parameters" value="true"/>
</map:transform>

Testing whether certain criteria matches then apply template

<xsl:for-each select="paragraph">   
 <xsl:if test="visible = 1">  
  <xsl:apply-templates/>             
 </xsl:if>     
</xsl:for-each>

attribute testing
[@name()!='name']
_with xsl:if

<xsl:if test="expression">
<!-- Content: template -->
</xsl:if>

_
with xsl:choose - block_

<xsl:choose>
	<xsl:when test=""></xsl:when>
	<xsl:otherwise></xsl:otherwise>
</xsl:choose>

_
If you test a string sometimes it is important that you don't have whitespaces!

normalize-space(.)

The following XPath expression selects all the cd elements of the catalog element that have a price element:

/catalog/cd[price]

Uppercase to lower case and vice versa

  <xsl:template match="upper-case">    
    <xsl:value-of select="translate(current(),
'abcdefghijklmnopqrstuvwxyz',
'ABCDEFGHIJKLMNOPQRSTUVWXYZ')" />
  </xsl:template>
 
  <xsl:template match="lower-case">    
    <xsl:value-of select="translate(current(),
'ABCDEFGHIJKLMNOPQRSTUVWXYZ',
'abcdefghijklmnopqrstuvwxyz')" />
  </xsl:template>

format Percent

  <xsl:template match="formatPercent">    
    <xsl:value-of select="concat('(',current(),'%)')" />
  </xsl:template>

format Currency

  <xsl:template match="formatCurrency">    
    <xsl:value-of select="concat(current(),'$')" />
  </xsl:template>
