xml - Enforcing validation of a secondary attribute based on another attribute in XSD -


question

is there way enforce subtype "percent" if basetype "percent"?

i mean, have validation fail if basetype "percent" subtype isn't "percent"?

xml partial

<quantity name="abc"  basetype="percent" value="2" subtype="percent"/>

xsd pertinent sections

          <xs:element name="thing">             <xs:complextype>               <xs:attribute name="name" type="xs:string" use="required"/>               <xs:attribute name="basetype" type="basetype" use="required"/>               <xs:attribute name="value" type="xs:double" use="required"/>               <xs:attribute name="subtype" type="subtype" use="required"/>             </xs:complextype>           </xs:element>    <xs:simpletype name="basetype">     <xs:restriction base="xs:string">         <xs:enumeration value="fixed"/>         <xs:enumeration value="percent"/>     </xs:restriction>   </xs:simpletype>     <xs:simpletype name="subtype">     <xs:restriction base="xs:string">         <xs:enumeration value="foo"/>         <xs:enumeration value="percent"/>         <xs:enumeration value="bar"/>     </xs:restriction>   </xs:simpletype>

xsd 1.0

xsd 1.0 cannot represent constraint.

xsd 1.1

xsd 1.1 can represent constraint using xs:assert:

<?xml version="1.0" encoding="utf-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/xmlschema"   xmlns:vc="http://www.w3.org/2007/xmlschema-versioning"   vc:minversion="1.1">    <xs:element name="quantity">     <xs:complextype>       <xs:attribute name="name" type="xs:string" use="required"/>       <xs:attribute name="basetype" type="basetype" use="required"/>       <xs:attribute name="value" type="xs:double" use="required"/>       <xs:attribute name="subtype" type="subtype" use="required"/>       <xs:assert test="(@basetype != 'percent') or (@subtype = 'percent')"/>     </xs:complextype>   </xs:element>    <xs:simpletype name="basetype">     <xs:restriction base="xs:string">       <xs:enumeration value="fixed"/>       <xs:enumeration value="percent"/>     </xs:restriction>   </xs:simpletype>    <xs:simpletype name="subtype">     <xs:restriction base="xs:string">       <xs:enumeration value="foo"/>       <xs:enumeration value="percent"/>       <xs:enumeration value="bar"/>     </xs:restriction>   </xs:simpletype>  </xs:schema>

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
