我有一个简单的XML和XSD文件。我使用Xerces生成.h / cpp文件但是当我运行应用程序时它会出错:
没有找到元素&x; x:books'
的声明
我的XML文件是:
<?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>
和XSD文件是:
<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>
我用Xerces做了一个更简单的演示,但是这个使用名称空间,我认为这似乎造成了麻烦。
答案 0 :(得分:2)
更改XML文件(urn:books
)的根元素上的命名空间以匹配XSD的targetNamespace
(urn:BookStore
)...
更改强>
<x:books xmlns:x="urn:books"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="urn:BookStore books.xsd">
以强>
<x:books xmlns:x="urn:BookStore"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="urn:BookStore books.xsd">
然后您的XML将根据您的XSD进行验证。
