1、测试的xml（test.xml）
<?xml version="1.0" encoding="UTF-8"?><BS_TCX><ServiceArea>area</ServiceArea><Version>1D</Version><IPVersion>6</IPVersion><MLDVersion>2</MLDVersion><NumOfTS>6</NumOfTS><TSList> <TS> <TSId>40F1</TSId> <MediaPortNumber>55101</MediaPortNumber> <GroupAddress>ff3e::9800:0</GroupAddress> <SourceAddress>2404:1a8:ffff:0:ff5b::192</SourceAddress> <CaBroadcasterGroupId>01</CaBroadcasterGroupId> <NumOfFEC>1</NumOfFEC> <FECList> <FEC> <FECMode>01</FECMode> <FECModeInfo>0A0A</FECModeInfo> </FEC> </FECList> <MaximumTSBitRate>10</MaximumTSBitRate> <NumOfService>2</NumOfService> <ServiceList> <Service> <ServiceName>hello</ServiceName> <ServiceId>0065</ServiceId> <LicenseId>0103000400000000</LicenseId> <TierBitMask>8000000000000000</TierBitMask> <ServiceType>01</ServiceType> <RemoteControlKeyId>1</RemoteControlKeyId> <StreamType>1b</StreamType> <RenderingObligation>92F0</RenderingObligation> <RenderingObligationRa>92F0</RenderingObligationRa> </Service> <Service> <ServiceName>EngService</ServiceName> <ServiceId>03A1</ServiceId> <ServiceType>A4</ServiceType> </Service> </ServiceList> </TS> <TS> <TSId>40D0</TSId> <MediaPortNumber>55102</MediaPortNumber> <GroupAddress>ff3e::9800:0</GroupAddress> <SourceAddress>2404:1a8:ffff:0:ff5b::193</SourceAddress> <CaBroadcasterGroupId>01</CaBroadcasterGroupId> <NumOfFEC>1</NumOfFEC> <FECList> <FEC> <FECMode>01</FECMode> <FECModeInfo>0A0A</FECModeInfo> </FEC> </FECList> <MaximumTSBitRate>10</MaximumTSBitRate> <NumOfService>2</NumOfService> <ServiceList> <Service> <ServiceName>hello</ServiceName> <ServiceId>008D</ServiceId> <LicenseId>0103000400000000</LicenseId> <TierBitMask>8000000000000000</TierBitMask> <ServiceType>01</ServiceType> <RemoteControlKeyId>4</RemoteControlKeyId> <StreamType>1b</StreamType> <RenderingObligation>92F0</RenderingObligation> <RenderingObligationRa>92F0</RenderingObligationRa> </Service> <Service> <ServiceName>hello</ServiceName> <!-- 142 --> <ServiceId>008E</ServiceId> <LicenseId>0103000400000000</LicenseId> <TierBitMask>8000000000000000</TierBitMask> <ServiceType>01</ServiceType> <StreamType>1b</StreamType> <RenderingObligation>DEF0</RenderingObligation> <RenderingObligationRa>DEF0</RenderingObligationRa> </Service> </ServiceList> </TS></TSList><SIMulticast> <MediaPortNumber>65010</MediaPortNumber> <GroupAddress>ff3e::9800:0</GroupAddress> <SourceAddress>2404:1a8:ffff:0:ff5b::10d</SourceAddress></SIMulticast></BS_TCX>2、python脚本（Xml_To_CSV.py）
