我必須從xml文件中提取數據並將其插入表

Question

<?xml version="1.0" encoding="UTF-8"?> 
<Document xmlns="urn:rocs.001.001.06"> 
<pokus> 
<RchEntry> 
     <PstlAdr> 
     <Ctry>IT</Ctry> 
    <AdrLine>VIA SARDEGNA, 12</AdrLine> 
     <AdrLine>00019TIVOLI RM</AdrLine> 
     </PstlAdr> 
    </RchEntry> 
    <RchEntry> 
    <PstlAdr> 
     <Ctry>IT1</Ctry> 
     <AdrLine>VIA SARDEGNA1, 12</AdrLine> 
     <AdrLine>00019TIVOLI11 RM</AdrLine> 
     </PstlAdr> 
    </RchEntry> 
    </pokus> 
</Document> 

這是我需要從中提取值的xml文件。每個RchEntry被視爲一行。我如何使用plsql提取AdrLine標記的值？
