Question

我正在尝试让我的XML架构处理一些可跟踪性功能，因为我在阅读一些功能规范时收集了需求。（不适合需求管理，但至少是一个开始。）

我正在做的是为我目前正在阅读的每个功能规范创建一个＆lt; functionalSpec＆gt; 标记。我为找到的每个要求创建了一个＆lt; 要求＆gt; 标记。由于我希望能够跟踪需求的来源，因此我使用＆lt; functionalSpec＆gt; id 创建一个＆lt; 跟踪＆gt; 元素em>元素。我希望XSD验证并确保我只输入 id ，而不是让自己在＆lt; functionalSpecId＆gt; 标记中输入任何普通旧文本。存在的现有功能规范。我的问题出现在XML Schema W3C Recommendations文档似乎说我不想做的事情。（约1/2左右）

{selector}指定相对于声明的元素的实例的受限XPath（[XPath]）表达式。这必须标识约束适用的从属元素的节点集（即包含在声明的元素中）。

我正在使用Oxygen来创建这个，因为我对XSD文件很新，它给了我以下错误：

E [Xerces] Identity Constraint error：identity constraint“KeyRef @ 1045a2”有一个keyref，它指的是超出范围的密钥或唯一。

所以我的问题是，是否有人知道一种方法可以让我通过使用XSD使用我下面的相同XML结构？

以下是XML文件。

<?xml version="1.0" encoding="UTF-8" ?> <srs xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="srs req2.xsd" xmlns="srs"> <requirements> <requirement DateCreated="2010-06-11" id="1"> <Text>The system shall...</Text> <trace> <functionalSpecId>B010134</functionalSpecId> </trace> <revisions> <revision date="2010-06-11" num="0"> <description>Initial creation.</description> </revision> </revisions> </requirement> </requirements> <functionalSpecs> <functionalSpec id="B010134" model="Model-T"> <trace> <meeting></meeting> </trace> <revisions> <revision date="2009-07-08" num="0"> <description>Initial creation.</description> </revision> <detailer>Me</detailer> <engineer>Me</engineer> </revisions> </functionalSpec> </functionalSpecs> </srs>

我很确定我已经完成了你想要实现的目标。诀窍是在更高级别定义唯一，键和keyref约束（在您的情况下为srs元素）。下面是一些代码示例，用于检查项目/ @ name中定义的“requires”元素：

请注意如何在项目级别定义约束。
