使用 python 解析不同的 xml 文件

Question

我有 2 个 xml 个文件，单词和主题。

我需要根据主题文件解析word文件。文件如下

文件 1 个主题

<?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?>
<nite:root nite:id="ES2002a.topic" 
xmlns:nite="http://nite.sourceforge.net/">
<topic nite:id="ES2002a.topic.vkaraisk.1" other_description="introduction of participants and their roles">
      <nite:pointer role="scenario_topic_type"  href="default-topics.xml#id(top.4)"/>
      <nite:child href="ES2002a.B.words.xml#id(ES2002a.B.words0)..id(ES2002a.B.words5)"/>
      <nite:child href="ES2002a.D.words.xml#id(ES2002a.D.words0)..id(ES2002a.D.words3)"/>
      <nite:child

文件 2 字 (ES2002a.B.words.xml)

<?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?>
<nite:root nite:id="ES2002a.B.words" xmlns:nite="http://nite.sourceforge.net/">
   <w nite:id="ES2002a.B.words0" starttime="50.42" endtime="50.99">Okay</w>
   <w nite:id="ES2002a.B.words1" starttime="50.99" endtime="50.99" punc="true">.</w>
   <w nite:id="ES2002a.B.words2" starttime="53.56" endtime="53.96">Right</w>
   <w nite:id="ES2002a.B.words3" starttime="53.96" endtime="53.96" punc="true">.</w>
   <vocalsound nite:id="ES2002a.B.words4" starttime="55.415" endtime="55.415" type="other"/>
   <w nite:id="ES2002a.B.words5" starttime="55.98" endtime="56.53">Um</w>

文件 2 字 (ES2002a.D.words.xml)

<?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?>
<nite:root nite:id="ES2002a.D.words" xmlns:nite="http://nite.sourceforge.net/">
   <w nite:id="ES2002a.D.words0" starttime="67.21" endtime="67.45">Mm-hmm</w>
   <w nite:id="ES2002a.D.words1" starttime="67.45" endtime="67.45" punc="true">.</w>
   <w nite:id="ES2002a.D.words2" starttime="74.89" endtime="75.24">Great</w>
   <w nite:id="ES2002a.D.words3" starttime="75.24" endtime="75.24" punc="true">.</w>
   <w nite:id="ES2002a.D.words4" starttime="82.08" endtime="82.25">And</w>
   <w nite:id="ES2002a.D.words5" starttime="82.25" endtime="82.43">I&#39;m</w>

有多个word文件需要根据主题文件进行解析。

  <nite:child href="ES2002a.B.words.xml#id(ES2002a.B.words0)..id(ES2002a.B.words5)"/>

我们看到主题文件说从文件 ES2002a.B.words

中获取单词 1-5

期望的输出是好的。正确的。嗯嗯嗯。很棒

题目文件里我已经解析过了，虽然代码很笨重

from lxml import etree
tree = etree.parse("./ES2013a.topic.xml") 
root = tree.getroot() 
childA = []
elementT = []
ElementA = []
for child in root:
    elementT.append(str(child.tag))
    ElementA.append(str(child.attrib))
    childA.append(str(child.attrib))
    for element in child:
        elementT.append(str(element.tag))
        #childA.append(child.attrib)
        ElementA.append(str(element.attrib))
        childA.append(str(child.attrib))
        for sub in element:
            #print('***', child.attrib , ':' , element.tag, ':' , element.attrib, '***')
            #childA.append(child.attrib)
            elementT.append(str(sub.tag))
            ElementA.append(str(sub.attrib))
            childA.append(str(child.attrib))

df = pd.DataFrame()
df['c'] = np.array (childA)
df['t'] = np.array(ElementA)
df['a'] = np.array(elementT)

file = df['t'].str.extract(r'([A-Z][A-Z].*[words.xml])#')
start = df['t'].str.extract(r'words([0-9]+)')
stop = df['t'].str.extract(r'.*words([0-9]+)')
tags = df['a'].str.extract(r'.*([topic]|[pointer]|[child])')
rootTopic = df['c'].str.extract(r'ES2013a.topic.rdhillon.(\d+)')
df['f'] = file
df['start'] = start
df['stop'] = stop
df['tags'] = tags
# c= topic
# r = pointerr
# d= child
df['topicID'] = rootTopic

df = df.iloc[:,3:]

我正在考虑使用一些 word 文件，然后根据开始和停止条件迭代 word 文件

Answer 1

我曾经用jxmlease来解析xml。它只是将 XML 字符串转换为 python dictionary。

topic.xml

<?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?>
<nite:root nite:id="ES2002a.topic" 
xmlns:nite="http://nite.sourceforge.net/">
<topic nite:id="ES2002a.topic.vkaraisk.1" other_description="introduction of participants and their roles">
      <nite:pointer role="scenario_topic_type"  href="default-topics.xml#id(top.4)"/>
      <nite:child href="ES2002a.B.words.xml#id(ES2002a.B.words0)..id(ES2002a.B.words5)"/>
      <nite:child href="ES2002a.D.words.xml#id(ES2002a.D.words0)..id(ES2002a.D.words3)"/>
</topic>
</nite:root>




import jxmlease

with open('topic.xml') as topic:
    topic_content = topic.read()

root = jxmlease.parse(topic_content)
first_word_selection = root['nite:root']['topic']['nite:child'][0].get_xml_attr("href")

print(first_word_selection)
output : ES2002a.D.words.xml#id(ES2002a.D.words0)..id(ES2002a.D.words3)

使用 python 解析不同的 xml 文件
