我嘗試了各種各樣的變化,從我的輸入中刪除一個節點是重複的。XQuery 1.0刪除重複的節點值
我使用的電流表達式如下:
<Signers>{
let $signers := fn:distinct-values($temp.load/*/Signers)
for $signer in $signers
return
<Signer>{
$signer
}</Signer>
}</Signers>
我甚至已經使用$簽名/ ID,$簽名/名稱等,但不產生所需的輸出。
輸入
<Signers>
<id>a1546000000xtaqAAA</id>
<email>[email protected]</email>
<name>Jack Rogers</name>
</Signers>
<Signers>
<id>a1546000000xwNSAAY</id>
<email>[email protected]</email>
<name>Walter White</name>
</Signers>
<Signers>
<id>a1546000000xwNSAAY</id>
<email>[email protected]</email>
<name>Walter White</name>
</Signers>
電流輸出
<Signers>
<Signer>[email protected] Rogers</Signer>
<Signer>[email protected]mail.comWalter White</Signer>
</Signers>
所需的輸出
<Signers>
<id>a1546000000xtaqAAA</id>
<email>[email protected]</email>
<name>Jack Rogers</name>
</Signers>
<Signers>
<id>a1546000000xwNSAAY</id>
<email>[email protected]</email>
<name>Walter White</name>
</Signers>
這必須是簡單的,我知道我忽視的東西。謝謝!
