  2. <xsl:element> <xsl:attribute> <xsl:element>: crea un nuovo elemento nell’output <xsl:attribute>: crea un nuovo attributo per un elemento dichiarato

  3. <xsl:template match=“/”> <html> <xsl:apply-templates/> </html> </xsl:template> <xsl:template match="teiHeader"> <table border='1‘> <tr><td> <xsl:apply-templates /> </td> </tr> </table> </xsl:template> <xsl:template match=“/”> <xsl:element name=“html”> <xsl:apply-templates/> <xsl:element> </xsl:template> <xsl:template match="teiHeader"> <table> <xsl:attribute name=“border”>1</xsl:attribute> <tr><td> <xsl:apply-templates /> </td> </tr> </table> </xsl:template> Esempio

  4. Inserire le immagini in un file TEI <?xml version="1.0"?> <?xml-stylesheet type="text/xsl" href="es25.xsl"?> <!DOCTYPE TEI.2 PUBLIC "-//TEI//DTD TEI Lite XML ver. 1//EN" "c:/TEI-EMACS/xml/dtds/tei/teixlite.dtd" [ <!ENTITY mummie1.jpg SYSTEM "mummie1.jpg" NDATA JPEG> <!ENTITY mummie2.jpg SYSTEM "mummie2.jpg" NDATA JPEG> <!ENTITY mummie3.jpg SYSTEM "mummie3.jpg" NDATA JPEG> <!ENTITY mummie4.jpg SYSTEM "mummie4.jpg" NDATA JPEG> <!ENTITY mummie5.jpg SYSTEM "mummie5.jpg" NDATA JPEG> ]>

  5. Elemento <figure> <head type="numerale">XIV <figure entity="mummie1.jpg"> <figDesc>Pagina 1</figDesc> </figure> </head>

  6. Visualizzazione <xsl:template match="figure"> <img> <xsl:attribute name="src"> <xsl:apply-templates select="@entity" /> </xsl:attribute> <xsl:attribute name="alt"> <xsl:apply-templates select="figDesc" /> </xsl:attribute> <xsl:attribute name="border">0</xsl:attribute> <xsl:attribute name="width">100%</xsl:attribute> <xsl:attribute name="heigth">100%</xsl:attribute> </img> </xsl:template>

  7. Risultato <img src=“mummie1.jpg” alt=“Pagina 1” border=“0” width=“100%” height=“100%”>  mummie.xml

  8. Visualizzare le note: il testo <head type="descrittivo">DIALOGO DI <name>FEDERICO RUYSCH</name> E DELLE SUE MUMMIE <note n="39" place="end">Vedi, tra gli altri, circa queste famose mummie, che in linguaggio scientifico si direbbero preparazioni anatomiche, il <bibl><author>Fontenelle</author> <title lang="fra">Eloge de <abbr expan="monsignore" type="title">mons.</abbr> <name>Ruysch</name></title></bibl>. </note> </head>

  9. HTML da ottenere <h3>DIALOGO DI FEDERICO RUYSCH E DELLE SUE MUMMIE <sup><a href=“#39”>39</a></sup></h3> <!-- qui tutto il testo --> <div> <hr> <p><a name=“39”><b>39.</b></a> Vedi, tra gli altri…</p> </div>

  10. Il rimando… <xsl:template match="note"> <sup> <a> <xsl:attribute name="href"> # <xsl:apply-templates select="@n"/> </xsl:attribute> <xsl:apply-templates select="@n"/> </a> </sup> </xsl:template>

  11. …e il testo <xsl:template match="body"> <body> <xsl:apply-templates /> <div> <hr/> <xsl:for-each select="//note"> <p> <a> <xsl:attribute name="name"> <xsl:value-of select="@n" /> </xsl:attribute> </a> <b> <xsl:value-of select="@n" />. </b> <xsl:text> </xsl:text> <xsl:value-of select="." /> </p> </xsl:for-each> </div> </body> </xsl:template>  mummie2.xml

  12. Attenzione: non usare due <body>! <xsl:template match="/"> <html> <head> <title> <xsl:apply-templates select="//titleStmt/title" /> </title> </head> <body> <xsl:apply-templates /> </body> </html> </xsl:template> <xsl:template match="body"> <body> … </body> </xsl:template>

  13. Sezioni condizionali • IF: booleano, qualora si verifichi una condizione si esegue una istruzione; se la condizione non si verifica l’istruzione non si esegue.Attributo test (sintassi XPath) obbligatorio • CHOOSE : si danno più opzioni • WHEN: booleano, qualora si verifichi una condizione si esegue una istruzione; se la condizione non si verifica l’istruzione non si esegue; ripetibile all’interno di choose; equivale a tanti ifAttributo test (sintassi XPath) obbligatorio • OTHERWISE ( else): contempla tutti i casi non definiti dai vari when

  14. Visualizzare solo poesie con titolo test non definisce un nuovo nodo contestuale. Il nodo contestuale è sempre poesia <xsl:template match="//poesia"> <xsl:if test="titolo"> <xsl:for-each select="titolo"> <b><xsl:value-of select="." /></b><br/> </xsl:for-each> <xsl:for-each select="verso"> <xsl:value-of select="." /><br/> </xsl:for-each> <br/> </xsl:if> </xsl:template>

  15. Se il titolo non c’è lo inseriamo test non definisce un nuovo nodo contestuale. Il nodo contestuale è sempre poesia <xsl:template match="poesia"> <xsl:choose> <xsl:when test="titolo"> <xsl:for-each select="titolo"> <b><xsl:value-of select="." /></b><br/> </xsl:for-each> </xsl:when> <xsl:otherwise> [<b>Poesia</b>]<br/> </xsl:otherwise> </xsl:choose> <xsl:for-each select="verso"> <xsl:value-of select="." /><br/> </xsl:for-each> <br/> </xsl:template>

  16. Un esempio complesso: table of content <xsl:template match="teiHeader“/> <xsl:template match="text"> <h1>Indice</h1> <ol> <xsl:for-each select="descendant::div1"><br/> <li> <xsl:choose> <xsl:when test="head"> <xsl:value-of select="head"/> <xsl:if test="head[position()=2]"> . <xsl:value-of select="head[position()=2]"/> </xsl:if> </xsl:when> <xsl:otherwise> <b><xsl:value-of select="@type"/></b> </xsl:otherwise> </xsl:choose> </li></xsl-for-each> </ol> </xsl:templates>

  17. Elenco con numero di occorrenze • Ceneri di Gramsci con marcatura delle parole rima: <lg><l>Teatro di dossi, ebbri, <s>calcinati</s>,</l> <l>muto, è la muta luna che ti <s>vive</s>,</l> <l>tiepida sulla Lucchesia dai <s>prati</s></l></lg> <lg><l>troppo umani, cocente sulle <s>rive</s></l> <l>della Versilia, cos&ì intera sul <s>vuoto</s></l> <l>del mare - attonita su <s>stive</s>,</l></lg>  Voglio un elenco delle parole rima per numero di occorrenze

  18. Elenco parole rima <xsl:template match="/"> <html> <body> <h3>Elenco parole rima</h3> <xsl:for-each select="//s">  Pasolini.xml <xsl:for-each select="//s[not(.=preceding::s)]"> <xsl:value-of select=“.”/> <br/> </xsl:for-each> </body> </html> </xsl:template>

  19. Elenco parole rima per numero di occorrenze <xsl:key name="rima" match="s" use="."/> <xsl:template match="/"> <html> <body> <h3>Elenco parole rima</h3> <xsl:for-each select="//s[not(.=preceding::s)]"> <xsl:sort select="count(key('rima',.))" data-type="number" order="descending" /><br /> <xsl:value-of select="concat(.,' ',count(key('rima',.)))"/> </xsl:for-each> </body> </html> </xsl:template>
