使用xml标记内的html标记进行lxml xml解析 [英] lxml xml parsing with html tags inside xml tags

问题描述

<xml>
<maintag>    
<content> lorem <br>ipsum</br> <strong> dolor sit </strong> and so on </content>
</maintag>
</xml>

我定期解析的xml文件可能在内容标签中包含html标签，如上所示.

The xml file that i regularly parse, may have html tags inside of content tag as shown above.

这是我解析文件的方式:

Here how i parse the file:

parser = etree.XMLParser(remove_blank_text=False)
tree = etree.parse(StringIO(xmlFile), parser)
for item in tree.iter('maintag'):
  my_content = item.find('content').text
  #print my_content
  #output: lorem

因此，结果为my_content =' lorem '，而不是-我想看到的-'lorem< br> ipsum< /br><强>多洛尔坐< /strong>，依此类推"

as a result it results my_content = 'lorem' instead of -which i'd like to see- ' lorem < br >ipsum< /br> < strong > dolor sit < /strong > and so on'

我如何将内容读为'lorem< br> ipsum< /br><强>多洛尔坐< /strong>等等?

How can i read the content as ' lorem < br>ipsum< /br> < strong > dolor sit < /strong > and so on'?

注意:内容标签可能具有其他html标签，而不是强标签.而且可能根本没有.

Note: content tag may have another html tags instead of strong. And may not have them at all.

推荐答案

from lxml import etree
root = etree.fromstring('''<xml>
<maintag>    
<content> lorem <br>ipsum</br> <strong> dolor sit </strong> and so on </content>
</maintag>
</xml>''')
for content in root.xpath('.//maintag/content'):
    print etree.tostring(content)

打印

<content> lorem <br>ipsum</br> <strong> dolor sit </strong> and so on </content>

---

....
for content in root.xpath('.//maintag/content'):
    print ''.join(child if isinstance(child, basestring) else etree.tostring(child)
                  for child in content.xpath('*|text()'))

打印

 lorem <br>ipsum</br>  <strong> dolor sit </strong> and so on  and so on
