python xml.etree.ElementTree 删除文本中间的空标签

Question

我有一个 xml 文档，我想根据标签从中提取文本。
我想从中提取文本的部分看起来像这样：

<BlockText attr1="blah" attr2=657 ID="Bhf76" lang="en">
Simply dummy text of the printing and typesetting industry. It has survived not only<TIP CONTENT="­"/>\n five centuries, electronic typesetting, remaining essentially release.
</BlockText>

当我做

tree = ET.parse("myfile.xml")
root = tree.getroot()
tags = list(set([elem.tag for elem in root.iter()]))
tag = list(filter(lambda i: "BlockText" in i, tags))[0]
for text in root.iter(tag):
    texte = text.text

我只能抓取空标签<TIP CONTENT=""/>之前的部分
我试图在获取其余文本之前删除此标签。
我做了：

emptyTag = list(filter(lambda i: "TIP" in i, tags))
for e in root.iter(emptyTag) :
    root.remove(e)

但这是行不通的。
<BlockText>和<TIP>都不是 root 的直接子代。


谢谢你。

Answer 1

<TIP CONTENT=""/>之后的文本属于它自己的尾部而不是BlockText标签的文本。

elem.text是 open 标签后面的文本。 elem.tail是关闭标签之后的文本。 通常是空白，但在这种情况下它有实际的文本。

Answer 2

好的，这就是最终对我有用的东西：

emptyTags = list(filter(lambda i: "TIP" in i, tags))
if emptyTags :
    emptyTag = list(filter(lambda i: "TIP" in i, emptyTags))[0]
for element in root.iter(emptyTag):
    print(element.tail)

但是我仍然无法将文本作为一个整体（相同的顺序）获取。 我可以获得所有的 BlockText 标签和所有的 TIP 标签，但不能同时获得。

更新 ：
我用了 ：

tree = ET.parse("myfile.xml")
root = tree.getroot()
tags = list(set([elem.tag for elem in root.iter()]))
tag = list(filter(lambda i: "BlockText" in i, tags))[0]
for text in root.iter(tag):
    texte = ''.join(text.itertext())

另一种解决方案仅供参考

from simplified_scrapy import SimplifiedDoc
html = '''
<BlockText attr1="blah" attr2=657 ID="Bhf76" lang="en">
Simply dummy text of the printing and typesetting industry. It has survived not only<TIP CONTENT="­"/>\n five centuries, electronic typesetting, remaining essentially release.
</BlockText>
'''
doc = SimplifiedDoc(html)
print (doc.select('BlockText'))
print (doc.select('BlockText>text()'))
print (doc.selects('BlockText>text()'))

结果：

{'tag': 'BlockText', 'attr1': 'blah', 'attr2': '657', 'ID': 'Bhf76', 'lang': 'en', 'html': '\nSimply dummy text of the printing and typesetting industry. It has survived not only<TIP CONTENT="\xad" />\n five centuries, electronic typesetting, remaining essentially release.\n'}
Simply dummy text of the printing and typesetting industry. It has survived not only five centuries, electronic typesetting, remaining essentially release.
