Before reading this tutorial, you should at least make sure that you are familiar with XML, have edited XML, DTD and XSLT documents using Notepad or other tools, and are familiar with their Grammar and usage, otherwise please make up the lesson before reading this tutorial.

XML Spy is an editor developed by Icon Information System that supports XML, XSL, XSLT, DTD, Schema and other file formats. It can display XML as a perfect tree structure, and can easily use various HTML/XML/XSLT tags. Using it can greatly save our development time, and we do not have to waste a lot of time on code input. Let's learn how to use XML Spy through an example of storing movie information.

Step one: We need to design three files: saveit.xml, saveit.dtd and saveit.xslt; saveit.xml is responsible for storing specific movie content data, and saveit.dtd is responsible for verifying saveit.xml. Saveit.xslt is responsible for style transformation of saveit.xml and determines its final display effect in the browser. Let’s first look at the code of the three files we need to create:

----------saveit.xml------------------
<?xml version="1.0" encoding="GB2312"?>
<!DOCTYPE movies SYSTEM "G:\xmlspy\saveit.dtd">
<?xml-stylesheet type="text/xsl" href="G:\xmlspy\saveit.xslt"?>
<movies type="动作片">
<id>1</id>
<name>致命摇篮</name>
<brief>李连杰最新力作!</brief>
<time>2003</time>
</movies>
----------saveit.dtd------------------
<?xml version="1.0" encoding="GB2312"?>
<!ELEMENT movies (id, name, brief, time)>
<!ATTLIST movies type CDATA #REQUIRED>
<!ELEMENT id (#PCDATA)>
<!ELEMENT name (#PCDATA)>
<!ELEMENT brief (#PCDATA)>
<!ELEMENT time (#PCDATA)>
----------saveit.xslt------------------
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="GB2312" indent="yes"/>
<xsl:template match="/">

<td>简介</td>

<td>类型</td>
</tr>
<tr>
<td><xsl:value-of select="name"></xsl:value-of></td>
<td><xsl:value-of select="brief"></xsl:value-of></td>
<td><xsl:value-of select="time"></xsl:value-of></td>
<td><xsl:value-of select="@type"></xsl:value-of></td>
</tr>
</tbody>
</table>
</xsl:template>
</xsl:stylesheet>
Copy after login

Step 2: Use XML Spy to create the saveit.dtd document.

1) Establish the root node movies

​Select the menu File->New to pop up the Create new document dialog box, select the dtd (Document Type Definition) inside, so that an empty DTD document will is established in the editing area, as shown in Figure 1. Click the black triangle in the upper left corner and it will look like Figure 2. We set the encoding method item encoding default value to UTF-8, and we changed it to GB2312. Double-click on Elm and enter movies. After completion, as shown in Figure 3. Keep Elm movies selectedstate, double-click the sequence of in the Elements box on the right, the result is shown in Figure 4. In this way, the root node movies is established.

2) Add child node id, name, brief, time and attribute type for the root node movies.

Right-click on the movies sequence of and select Add child ->ELEMENT, add four child nodes to it. As shown in Figure 5. Right-click on the movies sequence of again, select Append->ATTLIST, and then set its name to movies, set Name to type, set Type to CDATA, and set Presence to #REQUIRED as shown in Figure 6 .

3) Create sub-nodes id, name, brief, time. In movies Right-click on the sequence of, select Append->ELEMENT, add four nodes, and set all data types to PCDATA. As shown in Figure 7. In this way, the DTD document is created. Name it saveit.dtd and save it to the G:////xmlspy directory. In View->Text view mode, you can view the source code obtained by editing. Selecting View->Enhanced Grid view will return to tree editing View mode.

Step 3: Use XML Spy to create the saveit.xslt document.

1) Select the menu File->New to pop up the Create new document dialog box, select the last item xslt (Extensible Stylesheet Language), and create a new xslt file as shown in Figure 8 Show. At this time, XML Spy will automatically transfer the view to the code editing view, because it is more convenient to edit xslt directly. Change its encoding method to: GB2312, as shown in Figure 9.

2) The rest of the code can be easily added to the editing area through the Elements panel shown in Figure 10. After the addition is completed, set the corresponding nodes to the attribute values ​​of each element to complete the writing of the XSLT document. The specific process will not be detailed. After completion, it will look like Figure 11. Name it saveit.xslt and save it to the G:////xmlspy directory.

Step 4: Use XML Spy to create the saveit.xml document.

1) Select the menu File->New to pop up the Create new document dialog box, select xml (XML Document) inside, and a dialog box will pop up asking you to choose whether the XML document verification method is DTD or Schema. As shown in Figure 12, we select the DTD verification method and select the saveit.dtd just created as its verification document, as shown in Figure 13.

​ ​ ​ 2) After clicking OK, XML Spy will automatically build a saveit for us .dtd validated XML blank document. As shown in Figure 14. Fill in the content data. Change the encoding method item encoding to GB2312. The result is shown in Figure 15.

​ ​ 3) Select the XSL->Assign XSL menu, and select As shown in Figure 15), select the G:////xmlspy////saveit.xslt file and click OK.

4) You’re done, The XML document is finally edited. As shown in Figure 17. Name it saveit.xml and save it to the G:////xmlspy directory.

Step 5: You can select XSLT->XSL Transformation or click to view the final display effect of saveit.xml directly in XML Spy. You can also go to the G:////xmlspy directory and use a browser to watch it, but the browser must be IE6 or above. If you want to output the transformation result document, you can click to save the result document after transformation in XML Spy. The final display effect is shown in Figure 18. The above code passes Debugging in XML Spy5.
