TOPO DN 解析
介紹
有一個算法，是將大量TOPO DN實例解析成結構形式，並根據DN獲取相應的數據。本人感覺值得分享，並供大家討論與優化。
注意：TOPO DN實例的順序，是被我的其它算法預處理過的，所以會比較規整。
TOPO DN實例輸入片斷：
"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實例預期輸出片斷：
<ManagedElement > <InventoryUnitRack > <!-- 在完整的代碼中，這些地方會根據DN寫入數據 --> <InventoryUnitShelf > <InventoryUnitPack > <!-- 在完整的代碼中，這些地方會根據DN寫入數據 --> </InventoryUnitPack> </InventoryUnitShelf> </InventoryUnitRack> </ManagedElement> <ManagedElement > <IcscfFunction > <EpRpDynDnsIcscf > ...... </EpRpDynDnsIcscf> <EpRpDynCxIcscf > ...... </EpRpDynCxIcscf> <EpRpDynDxIcscf > ...... </EpRpDynDxIcscf> </IcscfFunction> <ScscfFunction > <EpRpDynCxScscf > ...... </EpRpDynCxScscf> </ScscfFunction> </ManagedElement>
核心代碼片斷：
