DbXml 操作修改节点值

dbxml数据库中有如下数据库：

<devices>
    <device>
        <id>01</id>
        <name>aa</name>
        <location>
            <id>001</id>
        </location>
    </device>
    <device>
        <id>02</id>
        <name>aa</name>
        <location>
            <id>001</id>
        </location>
    </device>
</devices>

修改所有device的location的所有id为001 的改成002。修改操作的查询语句如下：

strQuery="for $i in collection('devcon.dbxml')/devices/device/location[id='001'] return replace value of node $i/id with \"002\"";

修改后数据库结果变为：

<devices>
    <device>
        <id>01</id>
        <name>aa</name>
        <location>
            <id>002</id>
        </location>
    </device>
    <device>
        <id>02</id>
        <name>aa</name>
        <location>
            <id>002</id>
        </location>
    </device>
</devices>
