Question

我希望在标签<en>之间打印任何文字，只要x =＆＃39; PERS＆＃39;，我在下面尝试过，但输出不是我想要的。

XML示例

<Text>
<PHRASE>
<en x='PERS'> John </en>
<V> Went </V>
<prep> to </prep>
<V> meet </V>
<en x='PERS'> Alex </en>
</PHRASE>
<PHRASE>
<en x='PERS'> Mark </en>
<V> lives </V>
<prep> in </prep>
<en x='LOC'> Florida </en>
</PHRASE>
<PHRASE>
<en x='PERS'> Nick </en>
<V> visited</V>
<en x='PERS'> Anna </en>
</PHRASE>
</TEXT>

我想要输出： John-Alex，Nick-Anna。但我得到了：Mark-Mark。这意味着我只想在一个短语出现时打印2个PERS

这是我写的代码，我使用了元素树。

import xml.etree.ElementTree as ET
tree = ET.parse('output.xml')
root = tree.getroot()
print("------------------------PERS-PERS-------------------------------")
PERS_PERScount=0
for phrase in root.findall('./PHRASE'):
    ens = {en.get('x'): en.text for en in phrase.findall('en')}
    if 'PERS' in ens and 'PERS' in ens:
        print("PERS is: {}, PERS is: {} /".format(ens["PERS"], ens["PERS"]))
        #print(ens["ORG"])
        #print(ens["PERS"])
        PERS_PERScount = PERS_PERScount + 1
print("Number of PERS-PERS relation", PERS_PERScount)

我不确定问题是打印还是if条件，或两者都有？！

Answer 1

只有当属性if等于en 的 x元素的数量为时，您才可以添加简单的"PERS"检查以进行增量和打印2（一对）：

for phrase in root.findall('./PHRASE'): # get all inner text of elements where `x` attribute equals `"PERS"` names = [p.text.strip() for p in phrase.findall('./en[@x="PERS"]')] # if therea are 2 of them, increment counter and print if len(names) == 2: PERS_PERScount += 1 print('-'.join(names)) print("Number of PERS-PERS relation: ", PERS_PERScount)

<强> eval.in demo

输出

John-Alex Nick-Anna Number of PERS-PERS relation: 2

此：

#!/usr/bin/env python3

import xml.etree.ElementTree as ET

tree = ET.parse('output.xml')

root = tree.getroot()

print("------------------------PERS-PERS-------------------------------")

for phrase in root:
    if phrase.tag == 'PHRASE':
        collected_names = []
        for elt in phrase:
            if elt.tag == 'en':
                if 'x' in elt.attrib and elt.attrib['x'] == 'PERS':
                    collected_names += [elt.text]
        if len(collected_names) >= 2:
            print(collected_names[0] + " - " + collected_names[1])

将输出：

$ ./test_script
------------------------PERS-PERS-------------------------------
 John  -  Alex 
 Nick  -  Anna

但我不确定这是你想要的方式。

用Python打印XML文本文件？
