想要将价格转换为表示的价格范围,这样,我可以说“ 20美元以下”而不是17.95美元。使用xml:choose对我有用,但是当我尝试将结果放入类属性时,出现错误:

XSLT转换期间发生错误:发生未知错误()

我一直在阅读xsl:variable,但在这种情况下似乎找不到正确的方法来设置变量。

XML

    <?xml version="1.0" encoding="UTF-8"?>
    <productSearchResponse>
        <status>SUCCESS</status>
        <products found="20">
            <product>
                <itemNumber>50575</itemNumber>
                <itemName>Example 1</itemName>
                <price>$ 17.95</price>
            </product>

            ...

            <product>
                <itemNumber>81588</itemNumber>
                <itemName>Example 2</itemName>
                <price>$ 25.95</price>
            </product>
        </products>
    </productSearchResponse>


样式表

                    <xsl:variable name="priceNoSymbol" select="translate($price,'&#36;', '')"/>

                    <!-- Assign pricing bands -->
                        <xsl:choose>

最佳答案

我尚未详细研究整个问题,但您应该替换掉

<xsl:choose>
  <xsl:when test="$priceNoSymbol &lt; '20'">
    <xsl:variable name="priceBand" select="'under20'" />
  </xsl:when>
  <xsl:when test="$priceNoSymbol &gt; '39.99'">
    <xsl:variable name="priceBand" select="'20to40'" />
  </xsl:when>
  <xsl:otherwise>
    <xsl:variable name="priceBand" select="'over40'" />
  </xsl:otherwise>
</xsl:choose>




<xsl:variable name="priceband">
  <xsl:choose>
    <xsl:when test="$priceNoSymbol &lt; 20">under20</xsl:when>
    <xsl:when test="$priceNoSymbol &lt; 40">20to40</xsl:when>
    <xsl:otherwise>over40</xsl:otherwise>
  </xsl:choose>
</xsl:variable>




<xsl:variable name="priceNoSymbol" select="translate($price,'&#36;', '')"/>




<xsl:variable name="priceNoSymbol" select="number(translate($price,'&#36;', ''))"/>


当在这样的xsl:when元素内定义变量时,它几乎立即超出范围,并且在xsl:choose之外不可用。
