[英]Python - replace root element of one xml file with another root element without its children
我有一個 xml 文件,看起來像這樣,XML1:
<?xml version='1.0' encoding='utf-8'?>
<report>
</report>
另一個是這樣的,XML2:
<?xml version='1.0' encoding='utf-8'?>
<report attrib1="blabla" attrib2="blabla" attrib3="blabla" attrib4="blabla" attrib5="blabla" >
<child1>
<child2>
....
</child2>
</child1>
</report>
我需要替換並放置沒有子元素的 XML2 的根元素,因此 XML1 看起來像這樣:
<?xml version='1.0' encoding='utf-8'?>
<report attrib1="blabla" attrib2="blabla" attrib3="blabla" attrib4="blabla" attrib5="blabla">
</report>
目前我的代碼看起來像這樣,但它不會刪除子項,而是將整棵樹放在里面:
source_tree = ET.parse('XML2.xml')
source_root = source_tree.getroot()
report = source_root.findall('report')
for child in list(report):
report.remove(child)
source_tree.write('XML1.xml', encoding='utf-8', xml_declaration=True)
任何人都有 ide 我怎樣才能做到這一點?
謝謝!
嘗試以下(只需復制attrib )
import xml.etree.ElementTree as ET
xml1 = '''<?xml version='1.0' encoding='utf-8'?>
<report>
</report>'''
xml2 = '''<?xml version='1.0' encoding='utf-8'?>
<report attrib1="blabla" attrib2="blabla" attrib3="blabla" attrib4="blabla" attrib5="blabla" >
<child1>
<child2>
</child2>
</child1>
</report>'''
root1 = ET.fromstring(xml1)
root2 = ET.fromstring(xml2)
root1.attrib = root2.attrib
ET.dump(root1)
output
<report attrib1="blabla" attrib2="blabla" attrib3="blabla" attrib4="blabla" attrib5="blabla">
</report>
所以這是工作代碼:
source_tree = ET.parse('XML2.xml')
source_root = source_tree.getroot()
dest_tree = ET.parse('XML1.xml')
dest_root = dest_tree.getroot()
dest_root.attrib = source_root.attrib
dest_tree.write('XML1.xml', encoding='utf-8', xml_declaration=True)
