          <ul class="slides">
             <xsl:for-each select="entry/fields/*[@type = 'image']">

                   <img>
                     <xsl:attribute name="src">
                        <xsl:value-of select="data/@image"/>
                     </xsl:attribute>
                   </img>
                </li>
             </xsl:for-each>
          </ul>
       </div>
    </div>

 <div class="flex-container">
<div class="flexslider">
   <ul class="slides">
     <xsl:for-each select="entry/fields/*[@type = 'image' contains( ., 'img_' )]">
    <li>
     <img>
       <xsl:attribute name="src">
          <xsl:value-of select="data/@image"/>
         </xsl:attribute>
       </img>
     </li>
       </xsl:for-each>
     </ul>
  </div>
</div>

Can anyone help? I hope its the right form to ask here .

It seems, you just want to filter those images which are present, without breaking any link. So, you should use java extension to make it happen because XSLT only is not sufficient. Use something like:

<xsl:template match=file">
<xsl:variable name="file" select="resolve-uri(@name, base-uri(.))"
as="xs:string"/>
<xsl:if test="not(file:exists(file:new($file)))">
          <xsl:value-of select="@name"/><xsl:message>file missing /
incorrect name</xsl:message>
</xsl:if>
</xsl:template>
