Single Entity in Exchanger XML LiteEdit

The following directions will lead you step-by-step through doing the same project that is found in the XML - Managing Data Exchange/A single entity chapter.

Part One: Creating the Project FolderEdit

1) Open Exchanger XML Lite

2) Click on:

     -Project
      -New Project : a "New Project" folder will appear 
                in the project folder window

3) Type "TourGuide" over the "New Project" title to change the name of the new project to TourGuide.

 

Part Two: Creating the Schema FileEdit

1) Click on:

     -File
      -New 
      -For Type
       -Scroll to "XML Schema Definition" and highlight it
       -OK

2)Exchanger automatically puts the beginning and ending tags in the file for you, however, for our example, delete those automatic tags, and copy and paste the following code into the file:

<?xml version="1.0" encoding="UTF-8"?>
 <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="unqualified"> 
  <!-- Tour Guide -->
  <!--The tourGuide element is defined as a complex element type, i.e. 
    it has embedded elements.--> 
  <xsd:element name="tourGuide">
    <xsd:complexType>
      <xsd:sequence>
        <!--The minimum number of times an element can occur is 
         set using minOccurs (default is 1) and an unlimited 
        number of times an element can occur maxOccurs=”unbounded”.-->
        <xsd:element name="city" type="cityDetails" minOccurs = "1" maxOccurs="unbounded" />
      </xsd:sequence>
    </xsd:complexType>
   </xsd:element>
   <!-- City -->
   <!--City is declared an element of named complex type -->
   <!--<xsd:complexType begins the declaration of a complex 
type, ”cityDetails” identifies the complex type. 
   This is NOT the name of the element. This complex type 
   definition may be used in the declarations of more than one element.-->
   <xsd:complexType name="cityDetails">
    <!--Schema element sequence {13} specifies that the child elements 
    must appear in the order specified.-->
    <xsd:sequence>
       <!--<xsd:element begins the declaration of an element of simple 
       type. ”cityName” is the name of the element being declared (in 
       the XML document it will look something like: <cityName> ) 
       and ”xsd:string” is the data type of the element.--> 
       <xsd:element name="cityName" type="xsd:string"/>
       <xsd:element name="adminUnit" type="xsd:string"/>
       <xsd:element name="country" type="xsd:string"/>
       <xsd:element name="population" type="xsd:integer"/>
       <xsd:element name="area" type="xsd:integer"/>
       <xsd:element name="elevation" type="xsd:integer"/>
       <xsd:element name="longitude" type="xsd:decimal"/>
       <xsd:element name="latitude" type="xsd:decimal"/>
       <xsd:element name="description" type="xsd:string"/>
       <xsd:element name="history" type="xsd:string"/>
     <!--Closing of tags. Note: these should not overlap.--> 
     </xsd:sequence>
   </xsd:complexType>
 </xsd:schema>

3) Click on the GREEN CHECK to Validate, and the BROWN CHECK to check for Well-Formedness. These can be found on the toolbar:  

(NOTE: Be sure to eliminate any "white space" before the text that you paste, or you may have an error when validating.)

4)Click on:

  -File
  -Save
   -"city.xsd"

5)Right Click on:

  -"TourGuide" project folder
   -Add File
    -click on "city.xsd"
    -open
   
 (Note: Now the project "TourGuide" should contain one file,
    "city.xsd".)

Part Three: Creating the Style SheetEdit

1)Click on:

  -File
  -New
   -For Type
   -Scroll to "XML StyleSheet Language" and highlight it
    -OK

2)Delete any automatic tags that appear, and cut and paste the following code into the file:

<?xml version="1.0" encoding="UTF-8"?>
 <!--<xsl:stylesheet> declares start of stylesheet and identifies the version 
   number and the official W3C namespace.-->
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="html"/>
  <!--<xsl:template> defines the start of a template and contains 
  rules to apply when a specified node is matched. The match attribute is 
  used to associate (match) the template with an XML element, in this case 
  the root (/), or whole branch, of the XML source document. The XSL looks 
  for the root match and then outputs the HTML.--> 
  <xsl:template match="/">
    <!--The contents of the template element are placed in the output 
     stream of HTML that the browser will be able to interpret.-->
    <html>
      <head>
        <title>Tour Guide</title>
      </head>
      <body>
        <h2>Cities</h2>
        <xsl:apply-templates select="tourGuide"/>
      </body>
    </html>
  </xsl:template>
  <xsl:template match="tourGuide">
    <xsl:for-each select="city">
      <xsl:text>City: </xsl:text>
        <!--<xsl:value-of> extracts the value of the selected 
        node/XML element and adds it to the output stream-->
        <xsl:value-of select="cityName"/>
        <br/>
      <xsl:text>Population: </xsl:text>
        <xsl:value-of select="population"/>
        <br/>
      <xsl:text>Country: </xsl:text>
        <xsl:value-of select="country"/>
        <br/>
        <br/>
    </xsl:for-each>
  <!--<xsl:for-each> can be used to loop through each node in a specified 
     node set and add them to the output-->   
  </xsl:template>
 </xsl:stylesheet>

3) Click on the GREEN CHECK to Validate, and the BROWN CHECK to check for Well-Formedness. (NOTE: Be sure to eliminate any "white space" before the text that you paste, or you may have an error when validating.)

4)Click on:

  -File
   -Save As
   -"city.xsl"

5)Right Click on:

  -"TourGuide" project folder
   -Add File
   -"city.xsl"
    -open
  (Note: Now the project "TourGuide" contains two files, 
   "city.xsd", and "city.xsl".)

2) Delete any automatic tags that appear and copy and paste the following code:

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet href="city.xsl" type="text/xsl"?>

<!--The following declaration identifies the root element of the document 
(tourGuide) and the schema file (city.xsd) using xsi=schemaLocation-->
<tourGuide>
  xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
  xsi:noNamespaceSchemaLocation='city.xsd'>
  <!--The definition of the first city-->
