xml - How do I add namespaces to an XSD? -


the following xml , associated xsd:

xml 

<?xml version="1.0" encoding="utf-8" ?> <!-- <!doctype people system "validator.dtd"> -->  <people xmlns:xsi="http://www.w3c.org/200/10/xmlschema-instance" xsi:nonamespaceschemalocation="student.xsd">     <student>         <name>john</name>         <course>computer technology</course>         <semester>6</semester>         <scheme>e</scheme>     </student>      <student>         <name>foo</name>         <course>industrial electronics</course>         <semester>6</semester>         <scheme>e</scheme>     </student> </people>

xsd 

<?xml version="1.0"?>  <xs:schema xmlns:xs="http://www.w3.org/2001/xmlschema">     <xs:element name="people">         <xs:complextype>             <xs:sequence>                 <xs:element name="student" maxoccurs="unbounded">                     <xs:complextype>                         <xs:sequence>                             <xs:element name="name" type="xs:string" />                             <xs:element name="course" type="xs:string" />                             <xs:element name="semester">                                 <xs:simpletype>                                     <xs:restriction base="xs:string">                                         <xs:enumeration value="1" />                                         <xs:enumeration value="2" />                                         <xs:enumeration value="3" />                                         <xs:enumeration value="4" />                                         <xs:enumeration value="5" />                                         <xs:enumeration value="6" />                                     </xs:restriction>                                 </xs:simpletype>                             </xs:element>                             <xs:element name="scheme">                                 <xs:simpletype>                                     <xs:restriction base="xs:string">                                         <xs:pattern value = "e|c" />                                     </xs:restriction>                                 </xs:simpletype>                             </xs:element>                         </xs:sequence>                     </xs:complextype>                 </xs:element>             </xs:sequence>         </xs:complextype>     </xs:element> </xs:schema>

what want add namespace - hypothetical university students belong - say, carnegie mellon.

i know how add namespaces xml document. follows:
xmlns:cmu = "http://www.carnegiemellon.com/ns/students"
, there associated prefixes in xml.

what want know is: how validate xml prefixes using xsd?

my answer here should answer question... still, have consider following:

are people , student in same namespace? if yes, add targetnamespace uri mentioned. otherwise, have add xsd:import, , create new xsd targetnamespace want defines student.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
