XML to XSLT can open data from xml -

-

i have 2 files
xml file:

    <cadeiahoteis>     <hoteis id="1">             <codigo>458</codigo>              <morada>porto</morada>             <num_quartos>3</num_quartos>             <piscina>não</piscina>             <restaurante>                 <dados>sim</dados>                 <num_mesas>10</num_mesas>                 <num_pessoas>3</num_pessoas>                 <hora_abertura>11:30</hora_abertura>                 <hora_fechar>23:00</hora_fechar>             </restaurante>             <num_funcionarios>8</num_funcionarios>     </hoteis>     <hoteis id="2">      <codigo>381</codigo>              <morada>lisboa</morada>             <num_quartos>25</num_quartos>             <piscina>sim</piscina>             <restaurante>                  <dados></dados>                 <num_mesas></num_mesas>                 <num_pessoas></num_pessoas>                 <hora_abertura></hora_abertura>                 <hora_fechar></hora_fechar>             </restaurante>             <num_funcionarios>6</num_funcionarios>     </hoteis>

xslt file:

   <xsl:template match="ns:hoteis_">         <xsl:variable name="hoteis/id" select="@id_hotel"/>         <xsl:for-each select="//hoteis/restaurante">             <xsl:if test="dados != ' '">                 <tr>                     <td align="center">                          <xsl:value-of select= "ns:num_mesas" />                     </td>                     <td align="center">                          <xsl:value-of select= "ns:num_pessoas" />                     </td>                     <td align="center">                          <xsl:value-of select= "ns:hora_abertura" />                     </td>                     <td align="center">                          <xsl:value-of select= "ns:hora_fechar" />                     </td>                 </tr>             </xsl:if>             <xsl:if test="not(string(dados))">                 <tr>                     <td>dont exit restaurant <xsl:value-of select= "@id_hotel" />  </td>                 </tr>             </xsl:if>          </xsl:for-each>      </xsl:template>

i want t restaurant data if dados not empty not show, know how can show data??

since source elements unprefixed , there prefixed element selectors in xslt, i'm assuming all elements belong same namespace (which called your-namespace) , source starts this:

<cadeiahoteis xmlns="your-namespace">     <hoteis id="1">     ...

if that's not case, have make adjustments stylesheet below.

considering elements belonging namespace, stylesheet should declare , map prefix (ns). should use prefix qualify element selectors (or else not found, , none of tests work). finally, can test empty dados element normalize-space(ns:dados). better inside xs:choose block since can treat other case in xs:otherwise.

this stylesheet:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/xsl/transform"     xmlns:ns="your-namespace" version="1.0">      <xsl:strip-space elements="*"/>     <xsl:output indent="yes"/>     <xsl:template match="ns:cadeiahoteis">         <table>             <xsl:apply-templates/>         </table>     </xsl:template>     <xsl:template match="ns:hoteis">         <xsl:variable name="hoteis_id" select="@id"/>         <xsl:for-each select="ns:restaurante">             <xsl:choose>                 <xsl:when test="normalize-space(ns:dados)">                     <tr>                         <td align="center">                              <xsl:value-of select= "ns:num_mesas" />                         </td>                         <td align="center">                              <xsl:value-of select= "ns:num_pessoas" />                         </td>                         <td align="center">                              <xsl:value-of select= "ns:hora_abertura" />                         </td>                         <td align="center">                              <xsl:value-of select= "ns:hora_fechar" />                         </td>                     </tr>                 </xsl:when>                 <xsl:otherwise>                     <tr>                         <td>dont exit restaurant <xsl:value-of select= "@id_hotel" />  </td>                     </tr>                 </xsl:otherwise>             </xsl:choose>         </xsl:for-each>      </xsl:template> </xsl:stylesheet>

applied input data (with namespace attribute added above), produce result:

<?xml version="1.0" encoding="utf-8"?> <table xmlns:ns="your-namespace">    <tr>       <td align="center">10</td>       <td align="center">3</td>       <td align="center">11:30</td>       <td align="center">23:00</td>    </tr>    <tr>       <td>dont exit restaurant </td>    </tr> </table>

you can test , verify result here.

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
