TOPO DN 解析
介绍
有一个算法,是将大量TOPO DN实例解析成结构形式,并根据DN获取相应的数据。本人感觉值得分享,并供大家讨论与优化。
注意:TOPO DN实例的顺序,是被我的其它算法预处理过的,所以会比较规整。
TOPO DN实例输入片断:
"SubNetwork=HW-345678,ManagedElement=XXXX-1500/CSCF-1505", "SubNetwork=HW-345678,ManagedElement=XXXX-1500/CSCF-1505,InventoryUnitRack=RACK-1", "SubNetwork=HW-345678,ManagedElement=XXXX-1500/CSCF-1505,InventoryUnitRack=RACK-1,InventoryUnitShelf=RACK-1/SHELF-3", "SubNetwork=HW-345678,ManagedElement=XXXX-1500/CSCF-1505,InventoryUnitRack=RACK-1,InventoryUnitShelf=RACK-1/SHELF-3,InventoryUnitPack=RACK-1/SHELF-3/UNIT-5", "SubNetwork=HW-345678,ManagedElement=XXXX-1011/CSCF-1011", "SubNetwork=HW-345678,ManagedElement=XXXX-1011/CSCF-1011,IcscfFunction=CSCF-1011", "SubNetwork=HW-345678,ManagedElement=XXXX-1011/CSCF-1011,IcscfFunction=CSCF-1011,EpRpDynDnsIcscf=DNSPH-1", "SubNetwork=HW-345678,ManagedElement=XXXX-1011/CSCF-1011,IcscfFunction=CSCF-1011,EpRpDynCxIcscf=DIA-1", "SubNetwork=HW-345678,ManagedElement=XXXX-1011/CSCF-1011,IcscfFunction=CSCF-1011,EpRpDynDxIcscf=EPRPDX-1006", "SubNetwork=HW-345678,ManagedElement=XXXX-1011/CSCF-1011,ScscfFunction=CSCF-1011", "SubNetwork=HW-345678,ManagedElement=XXXX-1011/CSCF-1011,ScscfFunction=CSCF-1011,EpRpDynCxScscf=DIA-1"
TOPO DN实例预期输出片断:
<ManagedElement id="XXXX-1500/CSCF-1505"> <InventoryUnitRack id="RACK-1"> <!-- 在完整的代码中,这些地方会根据DN写入数据 --> <InventoryUnitShelf id="RACK-1/SHELF-3"> <InventoryUnitPack id="RACK-1/SHELF-3/UNIT-5"> <!-- 在完整的代码中,这些地方会根据DN写入数据 --> </InventoryUnitPack> </InventoryUnitShelf> </InventoryUnitRack> </ManagedElement> <ManagedElement id="XXXX-1011/CSCF-1011"> <IcscfFunction id="CSCF-1011"> <EpRpDynDnsIcscf id="DNSPH-1"> ...... </EpRpDynDnsIcscf> <EpRpDynCxIcscf id="DIA-1"> ...... </EpRpDynCxIcscf> <EpRpDynDxIcscf id="EPRPDX-1006"> ...... </EpRpDynDxIcscf> </IcscfFunction> <ScscfFunction id="CSCF-1011"> <EpRpDynCxScscf id="DIA-1"> ...... </EpRpDynCxScscf> </ScscfFunction> </ManagedElement>
核心代码片断:
