問題描述

我想為 XML 模式生成文檔.

I want to generate documentation for XML schemas.

我的目標是分析 xsd 文件并將其顯示為樹結構(解決所有復雜/匿名類型).此外，我需要用它們的基數(由模式定義)注釋該樹中的所有項目.

My goal is to analyze the xsd file and to display it as a tree structure (with all complex / anonymous types resolved). Furthermore I need to annotate all items in that tree with their cardinality (as defined by the schema).

下面的小例子可能有助于澄清我的問題.

The following small example might help to clarify my problem.

a) xsd 文件:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="client" type="clientType" />
    <xs:complexType name="clientType">
        <xs:sequence minOccurs="1" maxOccurs="1">
            <xs:element name="first_name"/>
            <xs:element name="last_name"/>
            <xs:element name="address" type="addressType" 
                        minOccurs="1" maxOccurs="unbounded"/>
        </xs:sequence>
    </xs:complexType>
    <xs:complexType name="addressType">
        <xs:sequence>
            <xs:element name="street"/>
            <xs:element name="number" minOccurs="0" maxOccurs="1"/>
            <xs:element name="city"/>
            <xs:element name="zipcode"/>
        </xs:sequence>
    </xs:complexType>
</xs:schema>

b) 我想看到的輸出:

b) Output I'd like to see:

client [1]
  first_name [1]
  last_name [1]
  address [1..n]
    street [1]
    number [0..1]
    city [1]
    zipcode [1]

有人知道這個問題的基于 java 的解決方案嗎?最好基于 Eclipse Schema Infoset，但我也很樂意使用其他庫.

Does anybody know a java based solution for this problem? Preferably based on Eclipse Schema Infoset, but I'm happy to use other libraries as well.

推薦答案

XSOM 可以將 XSD 規范化為可理解的數據結構，您可以循環并打印出來.

XSOM can normalize an XSD into a comprehensible data structure that you can loop over and print out.

這篇關于使用 Java 將 XSD 轉換為樹結構的文章就介紹到這了，希望我們推薦的答案對大家有所幫助，也希望大家多多支持html5模板網！
