Question

我正在尝试通过xslt将xml文件从ECB转换为xhtml，但我有一些错误。

这是XML文件

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="output.xsl"?>
<gesmes:Envelope xmlns:gesmes="http://www.gesmes.org/xml/2002-08-01"

            <Cube currency='ZAR' rate='11.0432'/>
        </Cube>
    </Cube>
</gesmes:Envelope>

这是我的XSLT文件

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="html" encoding="utf-8" doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN" doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"/>
 
    <xsl:template match="/">
        <html xmlns="http://www.w3.org/1999/xhtml">
        <head>
            <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
            <title>Exchange rates</title>

     </head>

        <body>
            <table>
                <tr>
                    <th>Rate</th>
                </tr>
            <xsl:for-each select="/gesmes:Envelope/Cube/Cube/Cube">
             <tr>
                    <td><xsl:value-of select="Cube/[@currency='USD']"/></td>

                </tr>
                </xsl:for-each>

            </table>
        </body>
        </html>
    </xsl:template>
</xsl:stylesheet>

结果如下：

USD 1.3676
JPY 104.97
BGN 1.9558

等等

我需要一个解决方案，而不是如何获得正确的源代码。

Answer 1

好的！我没有看到。

您的主要问题是名称空间： XSLT引擎不知道什么是gesmes，所以你需要告诉它。因此，您需要将其添加到xsl：stylesheet标记中。

的xmlns：GESMES = “http://www.gesmes.org/xml/2002-08-01”

您需要为xml的默认命名空间添加和命名命名空间：

的xmlns：XX = “http://www.ecb.int/vocabulary/2002-08-01/eurofxref” 所以你的样式表将从：
开始
＆lt; xsl：stylesheet version =“1.0” 的xmlns：XSL = “http://www.w3.org/1999/XSL/Transform” 的xmlns：GESMES = “http://www.gesmes.org/xml/2002-08-01” 的xmlns：XX = “http://www.ecb.int/vocabulary/2002-08-01/eurofxref” ＆GT;

你的每个人将是：＆lt; xsl：for-each select =“/ gesmes：Envelope / xx：Cube / xx：Cube / xx：Cube”＆gt;

它应该有效...但我建议您使用模板代替xsl：for-each

Answer 2

XSLT：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:ns="http://www.ecb.int/vocabulary/2002-08-01/eurofxref"
                xmlns:gesmes="http://www.gesmes.org/xml/2002-08-01">
    <xsl:output method="html" encoding="utf-8" doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN"
                doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"/>


    <xsl:template match="/">
        <html xmlns="http://www.w3.org/1999/xhtml">
            <head>
                <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
                <title>Exchange rates</title>
            </head>

            <body>
                <table>
                    <tr>
                        <th>Rate</th>
                        <th>Value</th>
                    </tr>
                    <xsl:apply-templates select="//ns:Cube/ns:Cube"/>


                </table>
            </body>
        </html>
    </xsl:template>

    <xsl:template match="ns:Cube">
        <tr xmlns="http://www.w3.org/1999/xhtml">
            <td>
                <xsl:value-of select="@currency"/>
            </td>
            <td>
                <xsl:value-of select="@rate"/>
            </td>
        </tr>
    </xsl:template>

</xsl:stylesheet>

输出：

好像你想要这样的东西（我刚刚编辑了你的代码 - 我自己的解决方案会有所不同）：

我自己的解决方案更像是：

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:gesmes="http://www.gesmes.org/xml/2002-08-01"
 xmlns:ecb="http://www.ecb.int/vocabulary/2002-08-01/eurofxref"
 exclude-result-prefixes="ecb gesmes">
    <xsl:output method="xml" encoding="utf-8"
     doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN"
     doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"/>

    <xsl:strip-space elements="*"/>

    <xsl:template match="ecb:Cube/ecb:Cube">
        <html xmlns="http://www.w3.org/1999/xhtml">
            <head>
                <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
                <title>Exchange rates</title>
            </head>
            <body>
                <table>
                    <tr>
                        <th>Currency</th>
                        <th>Rate</th>
                    </tr>
                 <xsl:apply-templates/>
                </table>
            </body>
        </html>
    </xsl:template>

    <xsl:template match="ecb:Cube/ecb:Cube/ecb:Cube" priority="5">
            <tr>
                <td>
                    <b><xsl:value-of select="@currency"/></b>
                </td>
                <td>
                    <xsl:value-of select="@rate"/>
                </td>
            </tr>
    </xsl:template>
    <xsl:template match="text()"/>
</xsl:stylesheet>

通过xslt将xml更改为xhtml
