我想找出使用 java 的 xsom 的 xsd 元素的最小出现次数 maximm 出现次数。我得到了这段代码来找出复杂的元素。谁能帮我找出所有 xsd 元素的出现次数。至少给我一个代码片段用于查找事件的类和方法
xmlfile = "Calendar.xsd"
XSOMParser parser = new XSOMParser();
parser.parse(new File(xmlfile));
XSSchemaSet sset = parser.getResult();
XSSchema s = sset.getSchema(1);
if (s.getTargetNamespace().equals("")) // this is the ns with all the stuff
// in
{
// try ElementDecls
Iterator jtr = s.iterateElementDecls();
while (jtr.hasNext())
{
XSElementDecl e = (XSElementDecl) jtr.next();
System.out.print("got ElementDecls " + e.getName());
// ok we've got a CALENDAR.. what next?
// not this anyway
/*
*
* XSParticle[] particles = e.asElementDecl() for (final XSParticle p :
* particles) { final XSTerm pterm = p.getTerm(); if
* (pterm.isElementDecl()) { final XSElementDecl ed =
* pterm.asElementDecl(); System.out.println(ed.getName()); }
*/
}
// try all Complex Types in schema
Iterator<XSComplexType> ctiter = s.iterateComplexTypes();
while (ctiter.hasNext())
{
// this will be a eSTATUS. Lets type and get the extension to
// see its a ENUM
XSComplexType ct = (XSComplexType) ctiter.next();
String typeName = ct.getName();
System.out.println(typeName + newline);
// as Content
XSContentType content = ct.getContentType();
// now what?
// as Partacle?
XSParticle p2 = content.asParticle();
if (null != p2)
{
System.out.print("We got partical thing !" + newline);
// might would be good if we got here but we never do :-(
}
// try complex type Element Decs
List<XSElementDecl> el = ct.getElementDecls();
for (XSElementDecl ed : el)
{
System.out.print("We got ElementDecl !" + ed.getName() + newline);
// would be good if we got here but we never do :-(
}
Collection<? extends XSAttributeUse> c = ct.getAttributeUses();
Iterator<? extends XSAttributeUse> i = c.iterator();
while (i.hasNext())
{
XSAttributeDecl attributeDecl = i.next().getDecl();
System.out.println("type: " + attributeDecl.getType());
System.out.println("name:" + attributeDecl.getName());
}
}
}
