如何在标记xml外部提取文本 [英] how to extract text outside tags xml
问题描述
我想提取标签外的文本.例如，
I want to extract text outside tags. For example,
<body>
This is an exmaple
<p>
blablabla
</p>
<references>
refer 1
refer 2
</references>
</body>
我想仅在其他标签(p或引用)中没有文本的情况下获取文本"This is a example".我尝试了几种方法，但是没有用. Any1可以提供帮助吗?非常感谢.
I want to get the text "This is an example" only without text in other tags (p or reference). I tried several methods but does not work. Any1 can help? Big thanks.
推荐答案
您必须考虑标记内的文本，例如节点.使用测试节点text()检索文本节点.例子.鉴于:
You must think a text inside a tag like a node. A text node is retrieved using the test node text(). Example. Given:
<body>
This is an exmaple
<p>
blablabla
<\p>
<references>
refer 1
refer 2
<\references>
another example
<\body>
XPath:
"/body/text()"
将检索body的所有子文本节点，例如"This is a exmaple"和"another example"，而
Will retrieve all children text nodes of body, like "This is an exmaple" and "another example", while:
"/body/text()[1]"
将仅检索第一个，这是一个赞".如果需要所有后代文本节点，则可以使用:
will retrieve only the first one, "This is an exmaple". If you want all the descendant text nodes you can use:
"/body//text()"
或者，您希望第一个p内的所有文本节点:
or, you want all the text nodes inside first p:
"/body/p[1]//text()"
