使用 saxon xquery 从 xml 中删除元素 [英] removing an element from xml using saxon xquery

问题描述

我有一个这样的 xml:

Hi I have an xml like this:

<ns1:books><ns2:book category="WEB"><ns3:title lang="en">Learning XML</ns3:title>
<ns3:author>Erik T. Ray</ns3:author><ns3:year>2003</ns3:year><ns3:price>39.95</price>

使用 Saxon xquery 我想删除 ns3:author 元素，谁能告诉我我该怎么做?

Using Saxon xquery I want to remove the ns3:author element, could anyone let me know how can I do it ?

我知道有一个 fn:remove(..) 方法，但我不想使用它，因为它需要一个整数作为第二个参数

I know there is a fn:remove(..) method but I don't want to use that as it takes an integer as a 2nd argument

任何完整的代码将不胜感激

Any complete code will be much appreciated

还有对于撒克逊人，我正面临像

Also with saxon I am facing the error like

Caused by: net.sf.saxon.trans.StaticError: #...nt-node() external中的XQuery语法错误；复制 $temp#:超出查询结束的意外标记$"

Caused by: net.sf.saxon.trans.StaticError: XQuery syntax error in #...nt-node() external; copy $temp#: Unexpected token "$" beyond end of query

我使用了 xml

声明命名空间soapenv="http://www.w3.org/2003/05/soap-envelope";声明命名空间 reg="http://www.mycompany.com/internal/xsd/registrationservice";声明命名空间 reg1="http://www.mycompany.com/internal/xsd/registrationtypes";

declare namespace soapenv="http://www.w3.org/2003/05/soap-envelope"; declare namespace reg="http://www.mycompany.com/internal/xsd/registrationservice"; declare namespace reg1="http://www.mycompany.com/internal/xsd/registrationtypes";

declare variable $RegistrationServiceRequest := <reg:RegistrationServiceRequest><reg1:RegistrationAttributes>       <reg1:Username>fdf</reg1:Username><reg1:Password>passwdfdford1</reg1:Password>      <reg1:Title>Mdfdfr</reg1:Title><reg1:FirstName>fdsfdsfsd</reg1:FirstName>
            </reg1:RegistrationAttributes><reg1:AutoLogin> <reg1:AutoLogin1>trtrtrt</reg1:AutoLogin1></reg1:AutoLogin>
        </reg:RegistrationServiceRequest>;
        copy $temp := $RegistrationServiceRequest 
modify delete node $temp/reg1:AutoLogin
return $temp

但是当我尝试使用 zorba 时，它工作正常，唯一的问题是撒克逊人，错误在于复制行

but when i tried with zorba it worked fine , the only problem is with the saxon and the error is at copy line

知道如何解决这个问题吗?

Any idea how to fix this ?

谢谢

推荐答案

如果您想对文档进行小的更改，XQuery 不是您的最佳选择.您可以使用 XQuery 更新来完成，也可以使用 XSLT 来完成.单独使用 XQuery 是可能的，但非常麻烦.

If you want to make a small change to a document, XQuery is not your best choice. You can do it with XQuery update, or you can do it with XSLT. Doing it with XQuery alone is possible, but very cumbersome.
