如何使用xsom \ dom \ jaxb获得最大深度的xsd？

Question

如何使用xsom获得最大深度的xsd。

例如：每个复杂类型下的元素总数xsd？

此外，如果复杂类型是有根据该复杂类型元素的数量+使用DOM \ xsom \ JAXB

<?xml version="1.0" encoding="UTF-8"?> 
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified"> 
<xs:element name="root" type="root"> 
    <xs:annotation> 
     <xs:documentation> 
      Comment describing your root element 
     </xs:documentation> 
    </xs:annotation> 
</xs:element> 

<xs:complexType name="root"> 
    <xs:sequence> 
     <xs:element name="element_count" type="xs:string"></xs:element> 
     <xs:element name="employee" type="employee" maxOccurs="unbounded" minOccurs="0"></xs:element> 
    </xs:sequence> 
</xs:complexType> 

<xs:complexType name="employee"> 
    <xs:sequence> 
     <xs:element name="name" type="xs:string"></xs:element> 
     <xs:element name="ID" type="xs:string"></xs:element> 
     <xs:element name="Addresses" type="addresses" maxOccurs="1" minOccurs="0"></xs:element> 
    </xs:sequence> 
</xs:complexType> 

<xs:complexType name="addresses"> 
    <xs:sequence> 
     <xs:element name="address" type="address" maxOccurs="unbounded" minOccurs="0"></xs:element> 
    </xs:sequence> 
</xs:complexType> 

<xs:complexType name="address"> 
    <xs:sequence> 
     <xs:element name="line1" type="xs:string"></xs:element> 
     <xs:element name="line2" type="xs:string"></xs:element> 
     <xs:element name="city" type="xs:string"></xs:element> 
     <xs:element name="type" type="xs:string"></xs:element> 
    </xs:sequence> 
</xs:complexType> 
</xs:schema>

我其实只是在寻找这个属性下那......。我在API中找不到任何东西，所以昨天找到了递归方式。我只是将我的递归方式粘贴到最深处并将它们添加到Hashmap中。

/* 
* Parses the xml schema string into a hashmap 
* note that hashmap has a form of a tree 
*/ 
public HashMap<String, Object> getXmlElements(InputStream xml) { 
    //--- 
    XSOMParser parser = new XSOMParser(); 
    //--- 
    try{ 
     parser.parse(xml); 
    } catch(Exception ex){ 
     logger.fatal("Could not parse the inputstream: " + ex); 
    } 
    //--- 
    XSSchemaSet schemaSet = null; 
    try { 
     schemaSet = parser.getResult(); 
    } catch (SAXException ex) { 
     logger.fatal("Could not parse: " + ex); 
    } 
    //--- 
    HashMap<String, Object> hmReturned = new HashMap<String, Object>(); 
    HashMap<String, Object> hm = new HashMap<String, Object>(); 
    Iterator <XSElementDecl> itre = schemaSet.iterateElementDecls(); 
    //--- 
    while(itre.hasNext()) { 
     XSElementDecl xse = (XSElementDecl) itre.next(); 
     hmReturned.put(xse.getName(), hm); 
     XSComplexType xscomp = xse.getType().asComplexType(); 
     if (xscomp != null) { 
      XSContentType xscont = xscomp.getContentType(); 
      XSParticle particle = xscont.asParticle(); 
      getElementsRecursively(hm, particle); 
     } 
    } 
    //--- 
    return hmReturned; 
} 

/* 
* recursive helper method of getXmlElements 
* note that since we don't know the "deepness" of the 
* schema a recursive way of implementation was necessary 
*/ 
private void getElementsRecursively(HashMap<String, Object> hm, XSParticle xsp) { 
    if(xsp != null){ 
     XSTerm term = xsp.getTerm(); 
     if(term.isElementDecl()) { 
      XSComplexType xscmp = (term.asElementDecl()).getType().asComplexType(); 
      //--- 
      if (xscmp == null){ 
       if(xsp.getMinOccurs() == 0) 
        hm.put(term.asElementDecl().getName(), "|"); 
       else 
        hm.put(term.asElementDecl().getName(), "="); 
      } else{ 
       XSContentType xscont = xscmp.getContentType(); 
       XSParticle particle = xscont.asParticle(); 
       HashMap<String, Object> newHm = new HashMap<String, Object>(); 
       getElementsRecursively(newHm, particle); 
       hm.put(term.asElementDecl().getName(), newHm); 
      } 
      //--- 
     } else if(term.isModelGroup()){ 
      XSModelGroup model = term.asModelGroup(); 
      XSParticle[] parr = model.getChildren(); 
      for(XSParticle partemp : parr){ 
       getElementsRecursively(hm, partemp); 
      } 
     } 
    } 
}
