Question

我有一个XML元素，在该元素下有注释。有没有办法用lxml删除注释？

<TEST name="1">
  <!--  test values: 1, 2, 3-->
  <file name="test1.py" /> 
</TEST >
<RESULT name="r1" value="false">
  <!--  result values: true, false-->
</RESULT >

我想将元素“TEST”下的注释更改为：

<TEST name="1">
  <!--  test values: 1, 2, 3, 4, 5-->
  <file name="test1.py" /> 
</TEST >
<RESULT name="r1" value="false">
  <!--  result values: true, false-->
</RESULT >

由于

Answer 1

<field name="Payload" type="text_general" indexed="true" stored="true"/>

出：

from lxml import etree

html = '''
<root>
<TEST name="1">
  <!--  test values: 1, 2, 3-->
  <file name="test1.py" /> 
</TEST >
<RESULT name="r1" value="false">
  <!--  result values: true, false-->
</RESULT >
</root>'''

r = etree.fromstring(html)
comments = r.xpath(r'//comment()')
for c in comments:
    p = c.getparent()
    p.remove(c)
print (etree.tostring(r))

Answer 2

import lxml.etree as et

xml = '''
<head>
<TEST name="1">
  <!--  test values: 1, 2, 3-->
  <file name="test1.py" />
</TEST >
<RESULT name="r1" value="false">
  <!--  result values: true, false-->
</RESULT >
</head>
'''

tree=et.fromstring(xml)

for bad in tree.xpath("//head/TEST/comment()"):
    bad.text += ', 4, 5'

print(et.tostring(tree, pretty_print=True))
