xml - Check if string is empty or not -

how can check if value empty or not xsl? example, if dadosis empty?

<hoteis id="1">         <codigo>458</codigo>          <morada>porto</morada>         <num_quartos>3</num_quartos>         <piscina>não</piscina>         <restaurante>              <dados></dados>             <num_mesas></num_mesas>             <num_pessoas></num_pessoas>             <hora_abertura></hora_abertura>             <hora_fechar></hora_fechar>         </restaurante> </hoteis>

for example:

<td align="center">      <xsl:value-of select= "ns:restaurante" >          <xsl:for-each select="/hoteis/restaurante">               <xsl:if teste="dados != ''">                     <tr bgcolor="#9acd32">                            <td align="center">nº pessoas</td>                            <td align="center">nº mesas</td>                            <td align="center">hora abertura</td>                            <td align="center">hora fechar</td>                     </tr>                     <xsl:apply-templates select="//ns:restaurante"/>                </xsl:if>           </xsl:for-each>       </xsl:value-of>  </td>

how can this?

your method work if had used test instead of teste (unless have spanish portugese xslt processor...?).

personally, prefer:

<xsl:if test="dados/text()">

note test existence of text node, child of dados - not same thing testing dados being empty.

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 $row): ?> <div id="<?=$...
