需要提取标签之间的文本

Question

我有以下 XML。我正在尝试在每个 <TextRegion> 标签之间提取 <Unicode> 中的文本。因此，每次打开和关闭</TextRegion> 的<TextRegion> 标签时，它们之间可能会有一个标签<Unicode> Sample Text </Unicode>。

我正在尝试提取此文本并将它们存储在单独的列表中。有人可以帮我吗。我使用 Elementtree 尝试了一些东西，但我完全迷失了。

阅读 xpaths 可能会对您有所帮助。 https://www.w3schools.com/xml/xpath_intro.asp

虽然您的目标在问题中有些不清楚，但以下是如何在 <TextRegion> 标记中提取 <Unicode> 标记中的所有文本。

In [1]: from lxml import etree

In [2]: root = etree.parse("page.xml")

In [3]: root.xpath('//TextRegion//Unicode/text()')
Out[3]: 
['r>',
 'B',
 'AT',
 '(U.K.',
 'and',
 'EXPORT)',
 'limited',
 'Export',
 'House',
 'Woking',
 'Surrey',
 'GU211YB',
 'England']
