Question

我目前正在做一个老师给我的家庭作业。我将创建一个XSL样式表，显示来自不同xml文件的数据。

我创建了一个名为weather.xsl的XSL文件，该文件显示了我老师给出的两个xml文件中的天气数据，名为IDN10031.xml和IDN11032.xml。

两个xml文件如下所示：

IDN10031.xml

我需要使用IDN10031.xml作为我的主文档，然后使用XSLT document()函数从IDN11032.xml获取天气数据

以下是我的XSL样式表现在的样子：

<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">

<xsl:template match="product">
    <html>
        <head>
            <title>State Weather</title>
            <link rel="stylesheet" href="weather.css"/>
        </head>
        <body>
            <h3>NSW and ACT Weather</h3>
                <p>Forecast for the rest of <xsl:value-of select="forecast/area/forecast-period/@start-time-local"/></p>
                <p><xsl:value-of select="forecast/area/forecast-period[2]/text[2]"/></p>
                <br/>
            <h3>Snowy Mountains District Weather</h3>
                <xsl:for-each select="document('IDN11032.xml')/product/forecast/area[@aac = 'NSW_PW010']/forecast-period[position() &lt; 4]">
                    <xsl:variable name="current_index" select="@index"/>
                    <p>Forecast for <xsl:value-of select="format-date(xs:date(substring(current()/@start-time-local,1,10)), '[FNn] [D1] [MNn]')"/></p>
                    <p><xsl:value-of select="text[@type = 'forecast']"/></p>
                        <table>
                            <xsl:sort select="parent::node()/@description"/>
                            <tr>
                                <td><xsl:value-of select="parent::node()/description"/></td>
                                <td><xsl:value-of select="text[@type = 'precis']"/></td>
                                <td><xsl:value-of select="element[@type = 'air_temperature_minimum']"/></td>
                                <td><xsl:value-of select="element[@type = 'air_temperature_maximum']"/></td>
                            </tr>
                        </table>
                </xsl:for-each>
        </body>
    </html>
</xsl:template>

</xsl:stylesheet>

在我添加'雪山区天气'的数据之前，它工作正常。所以我认为我的问题在实现document()函数和表时开始了。

这是我想要实现的结果：

自从我将document()函数与表一起实现后，我的样式表没有显示任何内容。

任何人都可以帮助我... 非常感谢，谢谢。

XSLT document（）函数 - for循环表不起作用
