DOMDocument验证中的XSD架构无效

我有一个格式如下的XML文档:

<?xml version="1.0" encoding="utf-8"?>
<books-feed xmlns="{NS-URL}">
<generation-date>{DATE}</generation-date>
<book id="{BOOK-ID}">
    <title>{BOOK-TITLE}</title>
    <author>{BOOK-AUTHOR}</author>
    .......................................... ← other information tags [any]
</book>
.............................................. ← other <book> elements
</books-feed>

我正在尝试使用此XSD架构验证此文件:

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="books-feed">
    <xsd:complexType>
        <xsd:sequence>
            <xsd:element name="generation-date" type="xsd:string"/>
            <xsd:element name="book" maxOccurs="unbounded">
                <xsd:complexType>
                    <xsd:sequence>
                        <xsd:any maxOccurs="unbounded" processContents="lax"/>
                    </xsd:sequence>
                    <xsd:attribute name="id" type="xsd:integer" use="required"/>
                </xsd:complexType>
            </xsd:element>
        </xsd:sequence>
    </xsd:complexType>
</xsd:element>
</xsd:schema>

所以DOMDocument :: schemaValidate()返回FALSE。命名空间中的这个问题(books-feed xmlns =“{NS-URL}”不等于schema xmlns)?或者我需要为xmlns book-feed插入xsd:attribute到schema(将导致“Invalid schema”警告)。或者是什么?

答案 0 :(得分:1)

实际问题应该记录在error_log中。

或者,请参阅此评论:http://www.php.net/manual/en/domdocument.schemavalidate.php#71014

要点:

设置libxml_use_internal_errors(true),然后使用libxml_get_errors()检索错误。然后使用libxml_use_internal_errors(false)

再次将其关闭

是的,您必须确保您的XSD的targetNamespace与根元素之一匹配。

<xsd:schema xmlns="{NS-URL}" attributeFormDefault="unqualified" elementFormDefault="qualified" targetNamespace="{NS-URL}" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <xsd:element name="books-feed">
          ....
  </xsd:element>
</xsd:schema>

假设您希望XSD与提供的XML匹配,那么您的有效XSD可能如下所示:

<?xml version="1.0" encoding="utf-8"?>
<!--XML Schema generated by QTAssistant/XML Schema Refactoring (XSR) Module (http://www.paschidev.com)-->
<xsd:schema xmlns="{NS-URL}" attributeFormDefault="unqualified" elementFormDefault="qualified" targetNamespace="{NS-URL}" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <xsd:element name="books-feed">
    <xsd:complexType>
      <xsd:sequence>
        <xsd:element name="generation-date" type="xsd:string" />
        <xsd:element maxOccurs="unbounded" name="book">
          <xsd:complexType>
            <xsd:sequence>
              <xsd:element name="title" type="xsd:string" />
              <xsd:element name="author" type="xsd:string" />
                    <xsd:any maxOccurs="unbounded" processContents="lax" minOccurs="0"/>
            </xsd:sequence>
            <xsd:attribute name="id" type="xsd:string" use="required" />
          </xsd:complexType>
        </xsd:element>
      </xsd:sequence>
    </xsd:complexType>
  </xsd:element>
</xsd:schema>
