Question

我希望能够以xml格式逐句处理不指定句子的句子。我的输入如下：

<p xmlns="https://jats.nlm.nih.gov/ns/archiving/1.0/"> 
Recently, a first step in this direction has been taken
in the form of the framework called &#8220;dynamical fingerprints&#8221;,
which has been developed to relate the experimental and MSM-derived
kinetic information.<sup><xref ref-type="bibr" rid="ref56">56</xref></sup> Several research
groups are now focused on developing protocols to systematically cross-validate
the MSM predictions and obtain MSM parameters using an optimization
protocol that produces the best estimate of the few slowest dynamics
modes of the protein dynamics.<sup><xref ref-type="bibr" rid="ref57">57</xref></sup></p>

我希望我的意见看起来更像是：

<p xmlns="https://jats.nlm.nih.gov/ns/archiving/1.0/">
<s>Recently, a first step in this direction has been taken

所以我可以提取这些整体：

<s xmlns="https://jats.nlm.nih.gov/ns/archiving/1.0/">Recently, a first step in this direction has been taken
in the form of the framework called &#8220;dynamical fingerprints&#8221;,

modes of the protein dynamics.<sup><xref ref-type="bibr" rid="ref57">57</xref></sup></s>

我的测试代码是：

from lxml import etree

if __name__=="__main__":

  xml1 = '''<p xmlns="https://jats.nlm.nih.gov/ns/archiving/1.0/">

  print xml1

  root = etree.XML(xml1)
  sentences_info = []
  for sentence in root:
    # I want to do more fun stuff here with the result
    sentence_text = sentence.text
    ref_ids = []
    for reference in sentence.getchildren():
        if 'rid' in reference.attrib.keys():
            ref_id = reference.attrib['rid']
            ref_ids.append(ref_id)
    sent_par = {'reference_ids': ref_ids,'text': sentence_text}
    sentences_info.append(sent_par)
    print sent_par

将BeautifulSoup对象转换为字符串然后使用正则表达式进行清理效果很好。例如：

'query_builder' => function(\Prfuk\WebquotaBundle\Entity\WorkplaceRepository $repository) {
        return $repository
            ->createQueryBuilder('s1')
            ->orderBy('s1.nazev','ASC');
    },

据我所知，没有内置的方法来处理xml中的句子，它需要自己的临时解决方案。

这是在解析XML时，它仍然包含命名空间。基本上，您解析的每个XML都具有以下元素：

<Element {https://jats.nlm.nih.gov/ns/archiving/1.0/}p at 0x108219048>

您可以remove namespace from XML使用以下功能：

from lxml import etree

def remove_namespace(tree):
    for node in tree.iter():
        try:
            has_namespace = node.tag.startswith('{')
        except AttributeError:
            continue  # node.tag is not a string (node is a comment or similar)
        if has_namespace:
            node.tag = node.tag.split('}', 1)[1]

然后解析XML并删除命名空间

tree = etree.fromstring(xml1)
remove_namespace(tree) # remove namespace
tree.findall('sup') # output as [<Element sup at 0x1081d73c8>, <Element sup at 0x1081d7648>]
