如何获取在变量中不重复的()数据。
我使用这个功能:
.
.
.
let $person:= $hopital1/persona
for $seq in (1 to count($derechohabiente))
return
$person[$seq]
[not(xf:is-node-secuence-equal(.,$person[position() < $seq])) ]
declare function xf:is-node-secuence-equal ( $node as node()? , $seq as node()*) as xs:boolean {
some $nodeInSeq in $seq satisfies fn:deep-equal($nodeInSeq/name, $node/ns0:name)
};
.
.
.
这是XML示例,我只想获取Joseph的信息,但我只得到重复的数据
<?xml version="1.0"?>
<hospital>
<person>
<idee>1902</idee>
<name>Joseph</name>
<age>60</age>
<room>4</room>
<service>false</service>
</person>
<person>
<idee>3246</idee>
<name>John</name>
<age>34</age>
<room>0</room>
<service>false</service>
</person>
<person>
<idee>3246</idee>
<name>John</name>
<age>34</age>
<room>0</room>
<service>true</service>
</person>
<person>
<idee>3246</idee>
<name>John</name>
<age>34</age>
<room>5</room>
<service>true</service>
</person>
</hospital>
从评论中更新
我想得到的数据不是 重复;如果你看到XML示例, 这是我想得到的结果:
<hospital> <person> <idee>1902</idee> <name>Joseph</name> <age>60</age> <room>4</room> <service>false</service> </person> </hospital>
答案 0 :(得分:1)
两个XQuery表达式:
/hospital/person[not(name = (../person except .)/name)]
和
/hospital/person[not(index-of(../person/name,name)[2])]
