recognize character entities

is there a way to recognize and filter only elements which text()
begins with a character entity?

 <Element>&Amp;This is filtered</Element>
 <Element>&epsilon;This filtered</Element>
 <Element>&euro;This is filtered</Element>
 <Element>This is *not* filtered</Element>
 <Element>And this also not</Element>

  <xsl:template match="Element[starts-with(text(),
'recognize_a_character_entity_here')]">
      <NewElement>
          <xsl:apply-templates select="@* | node()"/>
      </NewElement>
  </xsl:template>

for mathematical xml-files we have a lot (around 2000) character
entities to recognize and no chance to select them individually.

thanks in advance
for any help

(thanks to mukul, abel and michael for answering my apostrophe/
quotation mark question)
