                 <content>                       sacrifice. it's mass effect 3's major theme...                       <p />                       mass effect time , place; d...                       <p />                       mass effect 3 focused more on plot th...                       <p />                       <img url="me3_img1.jpg">plenty of games feat...</img>                       star wars, mass effect 3 inc...                       <p />                       reapers aren't adver...                       <p />                       <img url="me3_img2.jpg">if looks kill..</img>                       series' focus on player choice vi...                       <p />                       intense narrative met wi...                       <p />                       <img url="me3_img3.jpg">the sun sett...</img>                       these exquis...                  </content> 

each gap between paragraphs. each image must appear in-between paragraphs apear in content, must have caption, content being between , note has url , not src, must change.

my current xslt copy-of, , css fixes layout, img not displaying because can't change url src, aswell set caption.

please help.

update:

<xsl:for-each select='./review/content/child::*'>                           <xsl:value-of select="name()"/>                           <xsl:choose>                             <xsl:when test="name()='p'">                               <p />                             </xsl:when>                             <xsl:when test="name()='img'">                               <div class="reviewimage">                                 <img>                                   <xsl:attribute name="src">                                     <xsl:value-of select="./@url"/>                                   </xsl:attribute>                                 </img>                                 <xsl:value-of select="."/>                               </div>                                                             </xsl:when>                             <xsl:otherwise>                               <xsl:value-of select="."/>                             </xsl:otherwise>                           </xsl:choose>                         </xsl:for-each> 

it not outputing of text(). images , captions sorted though.

the point of copy-of copy content unchanged input tree output tree.

in order change between input , output trees, want use apply-templates , template.

if wish output element on output tree same name on input tree, different content, can use copy in template, , fill "copy" appropriate content.
