Well, it's hard to generalize from a small XML doc. But if all your 
submittedValues and display elements follow this regular pattern, this 
should work:

<xsl:template match="xml_root">
  <xsl:for-each select="submittedValues/submittedValue">
   <xsl:if test="./@fieldname=../following-sibling::*//input/@fieldname">
      <display>
          <p>title:
           <input type="text" fieldname="{@fieldname}">
             <xsl:attribute name="value"><xsl:value-of 
select="."/></xsl:attribute>
            </input>
          </p>
         </display>
   </xsl:if>
  </xsl:for-each>
</xsl:template>

(Btw, I changed the name of your root "xml" element to "xml_root." I didn't 
know if you really meant for an element to be called "xml" but if so, it 
offended what few purist sensibilities I still have. :)

Looks okay in IE5 (Sept. '00 release), and Saxon outputs:

<display>
    <p>title:
        <input type="text" fieldname="title" value="mr.">
    </p>
</display>

Sorry, I didn't use copy-of or recursive templates!
