Answer 1

样式表不生成任何表行的原因是源XML中没有价格大于或等于10的护发产品。

您的标题是“优惠高于.99c” - 如果您想展示价格高于0.99的产品，您需要提出您的条件：

<xsl:if test="Price &gt;= 1">

请注意，那些价格为.99c的XML产品不会通过此测试 - 但不是因为它们的价格低于阈值，而是因为它们的价格不是数字。要在比较中包含这些价格，您必须删除货币 - 例如：

<xsl:if test="translate(Price, 'c', '') &gt;= .5">

以上内容适用于XSLT 1.0，只要您的样式表继续标记为version="1.0"，就可以使用XSLT 2.0处理器。

Xsl如果测试要显示价格gt
