.net - Can XPath compare hexadecimal attribute values? -

-

simple task. here's xpath expression:

/methods/method[@token = '06000009']/sequencepoints/entry[string(@iloffset) <= string('00000e')][last()]

and here's part of xml document query:

<methods>   <method token="06000009">     <sequencepoints>       <entry iloffset="000000" startline="178" startcolumn="3" />       <entry iloffset="000001" startline="179" startcolumn="4" />       <entry iloffset="000008" startline="180" startcolumn="4" />       <entry iloffset="000009" startline="181" startcolumn="5" />       <entry iloffset="00000f" startline="182" startcolumn="4" />       <entry iloffset="000010" hidden="true" />       <entry iloffset="000022" hidden="true" />       <entry iloffset="000023" startline="183" startcolumn="3" />     </sequencepoints>   </method> </methods>

finds nothing. should find element:

<entry iloffset="000009" ...>

why doesn't work?

i'm not sure whether need string() conversion. without it doesn't work either. don't want xpath compare numbers because can go wrong hex values.

xpath 2.0:

yes. in scenario comparing 2 strings. legal , should work fine. if not working using xpath 1.0.

xpath 1.0:

not really. can compare strings = , != operators.

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