Question

如果我想提取“TEXT 1”但不“TEXT 2”和“TEXT 3”，我该如何编写XPath表达式？

<div class="content">
    <div>
        <p>
TEXT 1 <span class="author"> TEXT 2</span>
     <a href="http://www.example.com" class="more" name="_chf_A_xxlformat_">TEXT 3</a>
    </p>
</div>
</div>

您可能执行了<xsl:value-of select="text()"/>，它接受当前节点并将其递归转换为文本。 <xsl:value-of select="."/>仅选择文本节点，不包括子元素和属性。

这是一个完整的上下文XSLT：

text()

Answer 2

试试这个XPath：

$x("(//div[@class='content']/div/p/text())[1]");

也许这不是很安静，但它似乎做了它的工作:) 请注意，[1]将首次出现文本，如果更改文本位置，它将无法正常工作。

此致安德烈。

Answer 3

此XPath将选择作为p

的直接子项的文本节点

//div[@class='content']/div/p/text()

因此将排除“TEXT 2”和“TEXT 3”。

你可能更喜欢消除前导和尾随空格（并替换重复的内部空格，但无论如何）：

//div[@class='content']/div/p/text()[normalize-space()]

在XPath 1.0和XPath 2.0中评估为“TEXT 1”。

XPath选择除某些部分之外的文本
