我注意到Python的ElementTree模块在以下简单示例中更改了XML数据:
import xml.etree.ElementTree as ET
tree = ET.parse("./input.xml")
tree.write("./output.xml")
我不认为它会改变,因为我已经进行了简单的读写测试,没有做任何修改。然而,结果显示了一个不同的故事,特别是在命名空间索引方面(nonage --> ns0,d3p1 --> ns1,i --> ns2):
input.xml:
<?xml version="1.0" encoding="utf-8"?>
<ServerData xmlns:i="http://www.a.org" xmlns="http://schemas.xxx/2004/07/Server.Facades.ImportExport">
<CreationDate>0001-01-01T00:00:00</CreationDate>
<Processes>
<Processes xmlns:d3p1="http://schemas.datacontract.org/2004/07/Management.Interfaces">
<d3p1:ProtectedProcess>
<d3p1:Description>/Applications/Safari.app/Contents/MacOS/Safari</d3p1:Description>
<d3p1:DiscoveredMachine i:nil="true" />
<d3p1:Id>0</d3p1:Id>
<d3p1:Name>/applications/safari.app/contents/macos/safari</d3p1:Name>
<d3p1:Path>/Applications/Safari.app/Contents/MacOS/Safari</d3p1:Path>
<d3p1:ProcessHashes xmlns:d5p1="http://schemas.datacontract.org/2004/07/Management.Interfaces.WildFire" />
<d3p1:Status>1</d3p1:Status>
<d3p1:Type>Protected</d3p1:Type>
</d3p1:ProtectedProcess>
</Processes>
</Processes>
和output.xml文件:
<ns0:ServerData xmlns:ns0="http://schemas.xxx/2004/07/Server.Facades.ImportExport" xmlns:ns1="http://schemas.datacontract.org/2004/07/Management.Interfaces" xmlns:ns2="http://www.a.org">
