xsd validation - I need to validate this xml with xsd -


my xml file is

<?xml version="1.0" encoding="utf-8"?> <edge xmlns="http://www.example.org/stext"> <ellipse rx="189" ry="22" cx="279" cy="531"     style="fill:#fffdfd;stroke:#000000;" id="ellipse_23" islocked="false" /> <ellipse rx="130" ry="38" cx="580" cy="393"     style="fill:#fffdfd;stroke:#000000;" id="ellipse_19" islocked="false" /> <ellipse rx="172" ry="92" cx="539" cy="245"     style="fill:#bd7272;stroke:#d9b5b5;" id="ellipse_20" islocked="false" /> <circle r="51" cx="426" cy="284" style="fill:#bd7272;stroke:#d9b5b5;"     id="circle_16" islocked="false" /> <circle r="45" cx="428" cy="397" style="fill:#fffdfd;stroke:#302e2e;"     id="circle_17" islocked="false" /> </edge>

this xsd schema

<?xml version="1.0" encoding="utf-8"?> <schema xmlns="http://www.w3.org/2001/xmlschema" targetnamespace="http://www.example.org/stext" xmlns:tns="http://www.example.org/stext" elementformdefault="qualified"> <element name="edge">     <complextype>         <sequence>              <element name="circle" maxoccurs="unbounded">                 <complextype>                     <attribute name="r" type="int" />                     <attribute name="cx" type="int" />                     <attribute name="cy" type="int" />                     <attribute name="style" type="string" />                     <attribute name="id" type="string" />                     <attribute name="islocked" type="boolean" />                 </complextype>             </element>             <element name="ellipse" maxoccurs="unbounded">                 <complextype>                     <attribute name="rx" type="int" />                     <attribute name="ry" type="int" />                     <attribute name="cx" type="int" />                     <attribute name="cy" type="int" />                     <attribute name="style" type="string" />                     <attribute name="id" type="string" />                     <attribute name="islocked" type="boolean" />                 </complextype>             </element>         </sequence>     </complextype> </element> </schema>

i faced kind of exception

exception: cvc-complex-type.2.4.a: invalid content found starting element 'ellipse'. 1 of '{"http://www.example.org/stext":circle}' expected.

this happens, because <sequence> imposes specific order.

i think might solve problem, use additional xsd:choice element.

if write like

<sequence>    <choice  maxoccurs="unbounded">         <element name="circle">             <complextype>                 <attribute name="r" type="int" />                 <attribute name="cx" type="int" />                 <attribute name="cy" type="int" />                 <attribute name="style" type="string" />                 <attribute name="id" type="string" />                 <attribute name="islocked" type="boolean" />             </complextype>         </element>         <element name="ellipse">             <complextype>                 <attribute name="rx" type="int" />                 <attribute name="ry" type="int" />                 <attribute name="cx" type="int" />                 <attribute name="cy" type="int" />                 <attribute name="style" type="string" />                 <attribute name="id" type="string" />                 <attribute name="islocked" type="boolean" />             </complextype>         </element>     </choice>     </sequence>

that allow multiple circle or ellipse elements in order.

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)...
