XML第一次简单入门（Lab分析）

In this tutorial you will create a well-formed and verified XML file. Consider the XML document below

<?xml version="1.0"?>
<!DOCTYPE ancient_wonders [
<!ELEMENT ancient_wonders (wonder*)>
<!ELEMENT wonder (name, location, height)>
<!ELEMENT name (#PCDATA)>
<!ELEMENT location (#PCDATA)>
<!ELEMENT height (#PCDATA)>
<!ATTLIST height units CDATA #REQUIRED>
]>
<ancient_wonders>
<wonder>
<name>Colossus of Rhodes</name>
<location>Rhodes, Greece</location>
<height units="feet">107</height>
</wonder>
</ancient_wonders>

1. In the above XML document, add another ancient wonder element for the "Great Pyramid of Giza" located at Giza in Egypt and with the height of 455 feet. Save as “ancient-wonders.xml”

2. For element of Collossus of Rhodes in this XML document, just below the element, add an empty element <main_image> with attribute filename whose value is “colossus.jpg”.

3. Accomodate the DTD of “ancient-wonders.xml” to question 2.

4. Validate ancient-wonders.xml using xmllint.

5. Copy the “ancient_wonders” instance at the top (without DTD) to the XML instance document “ancient-wondersxsd.xml”.

6. Build an xml schema definition for ancient-wonders-xsd.xml and save it as “ancient-wonders.xsd”.

7. Validate the “ancient-wonders-xsd.xml” against “ancient-wonders.xsd” using xmllint. Submit the three documents via Stream.

第一，二，三问：

ancident-wonders.xml

<?xml version="1.0"?>
<!DOCTYPE ancient_wonders[
    <!ELEMENT ancient_wonders (wonder*)>
    <!ELEMENT wonder (name, main_image?, location, height)>
    <!ELEMENT name (#PCDATA)>
    <!ELEMENT main_image EMPTY>
    <!ATTLIST main_image filename CDATA #REQUIRED>
    <!ELEMENT location (#PCDATA)>
    <!ELEMENT height (#PCDATA)>
    <!ATTLIST height units CDATA #REQUIRED>
]>

<ancient_wonders>
        <wonder>
                <name>Colossus of Rhodes</name> 
                <main_image filename="colossus.jpg"/>
                <location>Rhodes, Greece</location> 
                <height units="feet">107</height> 
        </wonder>
        
        <wonder>
                <name>Great Pyramid of Giza</name> 
                <location>Giza, Egypt</location> 
                <height units="feet">455</height> 
        </wonder>
</ancient_wonders>

第五问：

<ancient_wonders>
        <wonder>
                <name>Colossus of Rhodes</name> 
                <main_image filename="colossus.jpg"/>
                <location>Rhodes, Greece</location> 
                <height units="feet">107</height> 
        </wonder>
        <wonder>
                <name>Great Pyramid of Giza</name> 
                <location>Giza, Egypt</location> 
                <height units="feet">455</height> 
        </wonder>
</ancient_wonders>

第六问：

<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="ancient_wonders">
      <xs:complexType>
        <xs:sequence minOccurs="0">
          <xs:element name="wonder" type="wonder" maxOccurs="10"/>
        </xs:sequence>
      </xs:complexType>
    </xs:element>
    
    <xs:complexType name="wonder">
      <xs:sequence>
        <xs:element name="name" type="xs:string"/>
        <xs:element name="main_image" type="main_image" minOccurs="0"/>
        <xs:element name="location" type="xs:string"/>
        <xs:element name="height" type="height"/> 
      </xs:sequence>
    </xs:complexType>
    
    <xs:complexType name="main_image">
      <xs:attribute name="filename" type="xs:string" use="required"/>
    </xs:complexType>

    <xs:complexType name="height">
      <xs:simpleContent>
        <xs:extension base="xs:integer">
          <xs:attribute name="units" type="xs:string" use="required"/>
        </xs:extension>
      </xs:simpleContent>
    </xs:complexType>
</xs:schema>
