Xpath 新手。试图在 SSIS 中使用 XML 任务来加载一些值。使用下面提到的 Microsoft 的 XML 清单。

如何在风格新颖且奖项=“普利策”的书店/书籍中加载名字值？ //book[@style='novel' and ./author/award/text()='Pulitzer']是我正在尝试的。它给出了整个元素。我应该在哪里修改以获得名字值？

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="myfile.xsl" ?>

我得到了答案。

//book[@style='novel' and ./author/award/text()='Pulitzer']//first-name

使用：

/*/book[@style='novel']/author[award = 'Pulitzer']/first-name

这将选择其父first-name元素具有字符串值为“普利策”的子元素且其（的）父元素为 a且其属性值为“novel”且其父元素为 XML 文档的顶部元素的任何元素。authorawardauthorbookstyle

相同上下文中的类似问题。我该怎么做，反之亦然？假设我想找到所有价格大于 20 的书籍的 id ？我知道我是在轻推，但我真的很想澄清我的理解。

这是需要的XPATH：

//book/price[text() > 20]/..
