XPath 正在返回包含标签的元素 [英] XPath is returning element including the tags

问题描述

我正在使用 xPath 读取 XML 文件，但是当尝试获取某个元素的内容时，它返回的内容包括标签 <> .

I am using xPath to read an XML file, but when trying to get the contents of a certain element, it returns it including the tags <> .

XML 文件的结构如下:

The XML file is structured like this:

<item>
    <attribute01>something</attribute01>
    <attribute02>something</attribute02>
    <attribute03>something</attribute03>
    <attribute04>
        <category>Some category name</category>
        <category>Some other category name</category>
    </attribute04>
</item>

我在//item 的上下文中工作，然后使用 attribute04//category 来获取类别元素.但是，这就是我要回来的:

I am working in the context of //item and then using attribute04//category to get the category element. However, this is what I'm getting back:

xpathparser:04 :
<Category>Bed &amp; Breakfast and Inns</Category>
xpathparser:04 :
<Category>Hotel</Category>
...etc...

它返回包括标签在内的整个元素.有人知道这里出了什么问题吗?

It returns the entire element including the tags. Does anybody have an idea what is going wrong here?

我正在将 Feeds xPath 解析器模块用于 Drupal (https://drupal.org/project/feeds_xpathparser).

推荐答案

为了在 XPath 表达式中选择节点的文本部分，您必须使用 text() 函数，如下所示:

In order to select the text portion of a node in an XPath expression you have to use the text() function as follows:

attribute04/category/text()

表达式

attribute04/category

将选择 XML 节点，而不是产生支撑标记和文本的输出.

will select the XML node instead resulting in the output of the bracings tags and the text.
