</xsl:stylesheet>

只是想看看我的DTD:

<!ELEMENT catalog (product+)>
<!ELEMENT product (title?, price, creation_date?, weight?, color, description?)>
<!ELEMENT creation_date (day, month, year)>

<!ATTLIST product id ID #REQUIRED>
<!ATTLIST product category (art|dinner_set|ovenware) "art">
<!ATTLIST price currency (AUS|USA) "AUS">
<!ATTLIST weight unit (gram|kilogram|ton) "gram">
<!ATTLIST year format (yy|yyyy) "yy">


<!ELEMENT id (#PCDATA)>
<!ELEMENT title (#PCDATA)>
<!ELEMENT price (#PCDATA)>
<!ELEMENT day (#PCDATA)>
<!ELEMENT month (#PCDATA)>
<!ELEMENT year (#PCDATA)>
<!ELEMENT weight (#PCDATA)>
<!ELEMENT color (#PCDATA)>
<!ELEMENT description (#PCDATA)>.

和Css,所以你们可以正确地运行这个:)

body{
    background-color: #fff;

}
table{
    border-collapse:collapse;
    border-spacing:0;
    padding: 10px;
    width: 100%;
    overflow: hidden;
}
td{
    font-family:Arial, sans-serif;
    font-size:14px;
    padding:10px 5px;
    overflow:hidden;
    word-break:normal;
    min-width: 80px;
    text-align: center;
    background-color: #E0E5DF;
    border-bottom: 2px solid #f6f6f6;
    border-top: 2px solid #f6f6f6;
}
th{
    font-family:Arial, sans-serif;
    font-size:14px;
    font-weight:normal;
    padding:10px 5px;
    overflow:hidden;
    word-break:normal;
    border-top: 4px solid #32517F;
    border-bottom: 2px solid #f6f6f6;
    background-color: #64A2FF;
}
tr:hover td{
    background-color: #81BDF7;
}
.description{
    width: 20%;
}

好的,如果你将所有这些发布到一个文件夹中,并将它们全部命名为&#34; test。(无论扩展名是什么)&#34;。所以test.xml,test.dtd等。

所以真正的问题是这里的一些代码:

<td><xsl:value-of select="weight"/>
    <xsl:choose>
        <xsl:when test="//weight[@unit = 'gram']">
            <span>g</span>
        </xsl:when>
        <xsl:when test="//weight[@unit = 'kilogram']">
            <span>&#32;Kg</span>
        </xsl:when>
        <xsl:otherwise>
            <xsl:if test="//weight > 1">
            <span>&#32;Tonnes</span>
            </xsl:if>
            <xsl:if test="//weight &lt;= 1">
            <span>&#32;Ton</span>
            </xsl:if>
        </xsl:otherwise>
    </xsl:choose>
</td>

它的意图是检查属性&#39;单位&#39;并根据它的值,然后在实际重量的末尾附加g,kg或ton。这部分效果很好。问题是它使用第一个并将其应用于所有三个表。

因此,对于我的xml中的示例,如果第一个产品权重,属性单位设置为kg,则所有表中的每个产品都设置为kg。

希望我已经足够好地解释了这一点,它实际上是有道理的。我发布了所有代码,所以你们可以为自己运行它们,似乎更容易尝试解释它。

谢谢,

乔尔

1 个答案:

答案 0 :(得分:1)

weightproduct的孩子,因此当您处于product的上下文中时,正确引用当前产品的权重为{{1}或者只是./weight - 而不是weight,它从根开始。

与您的问题无关,但您不应该为每个类别重复相同的代码。


编辑:

  

还有关于如何做的任何建议......

这是一些精简之后的例子:

//weight

可以通过循环一个类别列表来进一步做 - 可以是样式表中保存的静态列表,也可以是单独的文档,或者是通过从处理过的XML中提取唯一类别而得到的动态列表。
