问题描述

我有以下xml，其中包含多个带有xsi:nil ="true"的xml标记.这些是基本上为空的标签.我无法使用/查找任何sxlt转换器从xml中删除这些标签并获取xml的其余部分.

I have following xml which contains several xml tags with xsi:nil="true". These are tags that are basically null. I am not able to use/find any sxlt transformer to remove these tags from the xml and obtain the rest of the xml.

<?xml version="1.0" encoding="utf-8"?>
<p849:retrieveAllValues xmlns:p849="http://package.de.bc.a">
    <retrieveAllValues>
        <messages xsi:nil="true" />
        <existingValues>
            <Values>
                <value1> 10.00</value1>
                <value2>123456</value2>
                <value3>1234</value3>
                <value4 xsi:nil="true" />
                <value5 />
            </Values>
        </existingValues>
        <otherValues xsi:nil="true" />

推荐答案

错误原因

[致命错误] file2.xml:5:30:与元素类型消息"关联的属性"xsi:nil"的前缀"xsi"未绑定.

[Fatal Error] file2.xml:5:30: The prefix "xsi" for attribute "xsi:nil" associated with an element type "messages" is not bound.

没有声明名为"xsi"的前缀，您应该在根元素中指定它，例如:

is absence of prefix named "xsi" declared, you should specify it in root element such as:

<p849:retrieveAllValues xmlns:p849="http://package.de.bc.a"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<retrieveAllValues>
    <messages xsi:nil="true" />
       // other code...

更新

如果您无法更改从Web服务接收的xml文档，则可以尝试下一种方法(如果您可以接受此方法):

update

If you could not change xml document you're receiving from webservice, you could try next approach(if this approach is acceptable for you):

1. 更改您的xslt文档以处理xml文档而无需指定元素前缀
2. 设置namespaceAwarerel = "nofollow"> DocumentBuilderFactory 设置为false

1. Change your xslt document to process xml documents without specifying element prefixes
2. Set property namespaceAware of DocumentBuilderFactory to false

在此之后，您的变压器不应该抱怨

After this yout transformer shouldn't complain
