Erm - it was all supposed to be one solution.  Sorry I didn't make that
clearer.  Using your input:

---- test.xml ----
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="test.xsl"?>
<document>
  <para>
    content-1
    <List>
      <Item>content-2</Item>
      <Item>content-3</Item>
    </List>
    content-4
    <graphic/>
    content-5
  </para>
</document>
----

With the following stylesheet:

---- test.xsl ----
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version="1.0">

<xsl:output method="xml" indent="yes"/>

<xsl:template match="*" mode="flatten">
  <xsl:choose>
    <xsl:when test="*"><xsl:apply-templates mode="flatten" /></xsl:when>
    <xsl:otherwise>
      <xsl:copy-of select="." />
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>

<xsl:template match="text()" mode="flatten">
  <xsl:if test="normalize-space(.) != ''">
    <xsl:element name="{name(..)}">
      <xsl:value-of select="normalize-space(.)" />
    </xsl:element>
  </xsl:if>
</xsl:template>

<xsl:template match="document">
  <document>
    <xsl:apply-templates mode="flatten" />
  </document>
</xsl:template>

</xsl:stylesheet>
----

Gives the output:

---- out.xsl ----
<?xml version="1.0"?>
<document>
   <para>content-1</para>
   <Item>content-2</Item>
   <Item>content-3</Item>
   <para>content-4</para>
   <graphic/>
   <para>content-5</para>
</document>
----

Which is what you said you wanted.  This was using SAXON.

I hope that works for you now,
