xml - No declaration found for element -


i have simple xml , xsd files. using xerces generate .h/cpp files when run application gives error:

no declaration found element 'x:books'

my xml file is:

<?xml version="1.0"?> <x:books xmlns:x="urn:books"     xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xsi:schemalocation="urn:bookstore books.xsd">     <book id="bk001">       <author>writer</author>       <title>the first book</title>       <genre>fiction</genre>       <price>44.95</price>       <pub_date>2000-10-01</pub_date>       <review>an amazing story of nothing.</review>    </book>     <book id="bk002">       <author>poet</author>       <title>the poet's first poem</title>       <genre>poem</genre>       <price>24.95</price>       <pub_date>2001-10-01</pub_date>       <review>least poetic poems.</review>    </book> </x:books>

and xsd file is:

<xsd:schema xmlns:xsd="http://www.w3.org/2001/xmlschema"             targetnamespace="urn:bookstore"             xmlns:bks="urn:bookstore">    <xsd:element name="books" type="bks:booksform"/>    <xsd:complextype name="booksform">     <xsd:sequence>       <xsd:element name="book"                    type="bks:bookform"                    minoccurs="0"                    maxoccurs="unbounded"/>       </xsd:sequence>   </xsd:complextype>    <xsd:complextype name="bookform">     <xsd:sequence>       <xsd:element name="author"   type="xsd:string"/>       <xsd:element name="title"    type="xsd:string"/>       <xsd:element name="genre"    type="xsd:string"/>       <xsd:element name="price"    type="xsd:float" />       <xsd:element name="pub_date" type="xsd:date" />       <xsd:element name="review"   type="xsd:string"/>     </xsd:sequence>     <xsd:attribute name="id"   type="xsd:string"/>   </xsd:complextype> </xsd:schema>

i have done simpler demo xerces 1 uses namespaces , think seems causing trouble.

change namespace on root element of xml file (urn:books) match targetnamespace (urn:bookstore) of xsd...

change

<x:books xmlns:x="urn:books"          xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"          xsi:schemalocation="urn:bookstore books.xsd">

to

<x:books xmlns:x="urn:bookstore"          xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"          xsi:schemalocation="urn:bookstore books.xsd">

and xml validate against xsd.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
