php - trouble parsing xml with simplexml -


i pulling client info remote server , creating xml file on website parsed webpage. using code:

$xml=simplexml_load_file("test.xml");     print_r($xml);

outputs following:

simplexmlelement object ( [@attributes] => array ( [requesttype] => schema ) )

here xml file maybe can see if there error or in output:

    <b1reply:response requesttype="schema">     <b1reply:uri>/query/accountbalance.aspx?custcardcodefrom=c1007&custcardcodeto=c1007</b1reply:uri>     <b1reply:status>ok</b1reply:status>

if try echo single attribute, returns blank. i'm @ loss, , noob @ simplexml. appreciated.

first, xml not valid, see http://www.xmlvalidation.com

to select attributes of node, use xpath, here specific attribute specific node:

$xml = simplexml_load_string($x); // assume xml in $x $result = (string)$xml->xpath("//column[@name = '_custstatmenthdr_currency']/@alias")[0]; echo $result;

output:

currency

comments:

(1) code takes php >= 5.4 array dereferencing [0] in line 2
(2) cast (string), otherwise simplexml-object back

to column nodes attributes, do:

$results = $xml->xpath("//column"); foreach ($results $result) {     foreach ($result->attributes() $name, $value)         echo "$name: $value, ";     echo php_eol; }

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
