Examples of simultaneous use of XML, schema, and XSLT

I've never used a schema before, this time I wanted to add namespace to my XML file, schema, and then transform it into HTML with XSLT, but I didn't think it would take much effort. Now I have a good record of the results of the work, I hope to help some people.

Let's take a look at my XML file first. The menu that you intend to use to define the page.

<?xml version="1.0" encoding="GB2312"?>
<menu_items>
<menu_item href="index.html" image="images/A1.gif" name="首页"/>
<menu_item href="ep.html" image="images/A2.gif" name="新闻">
　　　 <menu_item href="ep.html" image="images/A2.gif" name="国内新闻"/>
</menu_item>
</menu_items>

Very simple XML file, put aside detours, with XMLSpy Generate schema function automatically generate schema files, and then make minor changes, the results are as follows:

<?xml version= "1.0" encoding= "GB2312"
<xs:schema xmlns= "http://www.hz-sp.com/2005/" Xmlschema-menu "xmlns:xs=" Http://www.w3.org/2001/XMLSchema "targetnamespace=" http://www.hz-sp.com/2005/　　 Xmlschema-menu ""
<xs:element name= "Menu_item"
<xs:complextype>
<xs:sequence>
<xs:element ref= "Menu_item" minoccurs= "0"/>
</xs:sequence>
<xs:attribute name= "name" Type= "XS : string "use=" required/>
<xs:attribute name= "href" type= "Xs:anyuri" use= "optional"/>
<xs: Attribute name= "image" Type= "Xs:anyuri" use= "optional"/>
</xs:complextype>
</xs:element>
<xs:element name= "Menu_items"
<xs:complextype>
<xs:sequence>
<xs:element ref= " Menu_item "maxoccurs=" unbounded "/>
</xs:sequence>
</xs:complextype>
</xs:element>
</xs:schema>

Among them, Http://www.hz-sp.com/2005/XMLSchema-menu is my namespace. This XSD is then specified in XML with the XMLSpy assign Schema feature, and the root node in the XML Menu_items is:

<menu_items xmlns="http://www.hz-sp.com/2005/XMLSchema-menu" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.hz-sp.com/2005/XMLSchema-menu
menu.xsd">

The next step is to create the XSLT file, which also gives the correct results:

<?xml version= "1.0" encoding= "GB2312"
<xsl:stylesheet xpath-default-namespace= "http://" Www.hz-sp.com/2005/XMLSchema-menu "version=" 2.0 "xmlns:xsl=" http://www.w3.org/1999/XSL/Transform "xmlns:xs=" http ://www.w3.org/2001/XMLSchema "xmlns:fn=" http://www.w3.org/2004/07/xpath-functions "xmlns:xdt=" http://www.w3.org/ 2004/07/xpath-datatypes "xmlns=" http://www.w3.org/1999/xhtml >>
<xsl:output encoding= "GB2312" indent= "Yes" method= "HTML" version= "4.0"/>
<xsl:template match= "Mm:menu_items" xmlns:mm= "http://www.hz-sp.com/"　　 2005/xmlschema-menu ""
<table width= "900" border= "0" cellspacing= "0" cellpadding= "0"
<tr>
<xsl:for-each select= "Mm:menu_item"
<a href= "{@href}"

</a>
</xsl:for-each>
</tr>
</table>
</xsl:templ Ate>
</xsl:stylesheet>

It is annoying that xpath-default-namespace= "http://www.hz-sp.com/2005/XMLSchema-menu" has no effect on the match of Xsl:template, and it is estimated that match is not Xpath. But this attribute has no effect on the select in For-each, which is odd, and I don't think I understand how this property should be used.
