  • 我有一个XML文档,其名称空间为ns2,默认名称空间为:

 <ns2:Products xmlns="https://www.schema.product.com" xmlns:ns2="https://www.schema.products.com">
        <Product ProductId="1">
            <ProductName> Hộp Hoa Hồng Trắng</ProductName>
            <ProductPrice>550000</ProductPrice>
            <ProductImage>https://dienhoa24gio.net//assets/upload/product/20-09-2015/hop-hoa-hong-trang-1442711392/274_default.jpg</ProductImage>
        </Product>
        <Product ProductId="2">
            <ProductName>An Lành</ProductName>
            <ProductPrice>780000</ProductPrice>
            <ProductImage>https://dienhoa24gio.net//assets/upload/product/17-10-2015/an-lanh-1445039808/274_default.jpg</ProductImage>
        </Product>
    </ns2:Products> 

用xsl文件显示表格,使用xml文件的数据

 <xsl:template match="//*[local-name()='Products']">
        <table border="1">
                    <tr>
                        <th>name</th>
                        <th>price</th>
                        <th>image</th>
                    </tr>
                    <xsl:for-each select="//*[local-name()='Product']">
                        <tr>
                            <td><xsl:value-of select="//*[local-name()='ProductName']"/></td>
                       
                            <td><xsl:value-of select="//*[local-name()='ProductPrice']"/></td>
                        
                            <td><xsl:value-of select="//*[local-name()='ProductImage']"/></td>
                        </tr>
                    </xsl:for-each>
                </table>
    </xsl:template>

  • 我导入2个文件(xml和xsl)并运行jsp

<c:import url="test.xml" var="xmlDoc" charEncoding="UTF-8"/>
        <c:import url="test.xsl" var="xslDoc" charEncoding="UTF-8"/>
        <x:transform xml="${xmlDoc}" xslt="${xslDoc}"/>

但是当运行jsp页面时,行表的数据是相同的,我不知道

<table border="1">
<tr>
<th>name</th><th>price</th><th>image</th>
</tr>
<tr>
<td> Hộp Hoa Hồng Trắng</td><td>550000</td><td>https://dienhoa24gio.net//assets/upload/product/20-09-2015/hop-hoa-hong-trang-1442711392/274_default.jpg</td>
</tr>
<tr>
<td> Hộp Hoa Hồng Trắng</td><td>550000</td><td>https://dienhoa24gio.net//assets/upload/product/20-09-2015/hop-hoa-hong-trang-1442711392/274_default.jpg</td>
</tr>
<tr>
<td> Hộp Hoa Hồng Trắng</td><td>550000</td><td>https://dienhoa24gio.net//assets/upload/product/20-09-2015/hop-hoa-hong-trang-1442711392/274_default.jpg</td>
</tr>
<tr>
<td> Hộp Hoa Hồng Trắng</td><td>550000</td><td>https://dienhoa24gio.net//assets/upload/product/20-09-2015/hop-hoa-hong-trang-1442711392/274_default.jpg</td>
</tr>
<tr>
<td> Hộp Hoa Hồng Trắng</td><td>550000</td><td>https://dienhoa24gio.net//assets/upload/product/20-09-2015/hop-hoa-hong-trang-1442711392/274_default.jpg</td>
</tr>
</table>

请帮助我修复此错误, 非常感谢

因为您从//开始所有内容,所以它将搜索整个文档,因此每次for-each查找产品时,它都会查找与第一个与ProductName匹配的元素,而不是当前Product元素中的ProductName。

请尝试以下xsl:

     <xsl:stylesheet 
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
        xmlns:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xs" version="2.0"><xsl:template match="//*[local-name()='Products']">
            <table border="1">
                        <tr>
                            <th>name</th>
                            <th>price</th>
                            <th>image</th>
                        </tr>
                        <xsl:for-each select="//*[local-name()='Product']">
                            <tr>
                                <td><xsl:value-of select="*[local-name()='ProductName']"/></td>

                                <td><xsl:value-of select="*[local-name()='ProductPrice']"/></td>

                                <td><xsl:element name="img">
<xsl:attribute name="src"><xsl:value-of select="*[local-name()='ProductImage']"/></xsl:attribute></xsl:element></td>
                            </tr>
                        </xsl:for-each>
                    </table>
        </xsl:template>
    </xsl:stylesheet>

输入

<ns2:Products xmlns="https://www.schema.product.com" xmlns:ns2="https://www.schema.products.com">
        <Product ProductId="1">
            <ProductName> Hộp Hoa Hồng Trắng</ProductName>
            <ProductPrice>550000</ProductPrice>
            <ProductImage>https://dienhoa24gio.net//assets/upload/product/20-09-2015/hop-hoa-hong-trang-1442711392/274_default.jpg</ProductImage>
        </Product>
        <Product ProductId="2">
            <ProductName>An Lành</ProductName>
            <ProductPrice>780000</ProductPrice>
            <ProductImage>https://dienhoa24gio.net//assets/upload/product/17-10-2015/an-lanh-1445039808/274_default.jpg</ProductImage>
        </Product>
    </ns2:Products> 

它给了我输出

<table border="1">
   <tr>
      <th>name</th>
      <th>price</th>
      <th>image</th>
   </tr>
   <tr>
      <td> Hộp Hoa Hồng Trắng</td>
      <td>550000</td>
      <td>https://dienhoa24gio.net//assets/upload/product/20-09-2015/hop-hoa-hong-trang-1442711392/274_default.jpg</td>
   </tr>
   <tr>
      <td>An Lành</td>
      <td>780000</td>
      <td>https://dienhoa24gio.net//assets/upload/product/17-10-2015/an-lanh-1445039808/274_default.jpg</td>
   </tr>
