proXML getElement string != ?
Jan 10th, 2006, 8:30am  
Hi people,

To get elements from xml I wrote a recursive function. But when comparing the getElement return value with the nodename I 'm looking for it always returns false. It does work with nodes created from within p55 however.
Code:
import proxml.*;
XMLElement xBse;
XMLInOut xmlInOut;
void setup() {
  try {
    xmlInOut = new XMLInOut(this);
    xBse = xmlInOut.loadElementFrom("http://www.sjeiti.com/"); 
  } catch(InvalidDocumentException ide) {
    println("File does not exist");
  }
//
//
  XMLElement xUol = new XMLElement("ul");
  xBse.addChild(xUol);
//
//
Vector vXML = getXML(xBse,"ul",-1,new Vector(0));
println("uls "+vXML.size());
for (int i=0; i<vXML.size(); i++) {
Vector vUls = getXML((XMLElement)vXML.elementAt(i),"li",-1,new Vector(0));
println("ul "+i+" "+vUls.size());
}
}

Vector getXML(XMLElement xXML, String sName, int iDepth, Vector vReturn) {
	if (iDepth>0) iDepth = iDepth-1;
	for (int i=0;i<xXML.countChildren();i++) {
		XMLElement xNode = xXML.getChild(i);
		if (!xNode.isPCDATA()) {
			String sNme = xNode.getElement();
			println(sNme+"=="+sName+" "+((sNme)==(sName))+" ____ ");
			if (xNode.getElement()==sName) {
				vReturn.add(xNode);
			}
			if (xNode.hasChildren()&&iDepth!=0) vReturn = getXML(xNode,sName,iDepth,vReturn);
		}
	}
	return vReturn;
}

As you can see in the printlines... the only "ul"=="ul" is the one I added in p55.
Is there some String thing I don't know about.

i haven't tested the code, but string equality in java is
tested with .equals(). so you should probably replace this:
Code:

if (xNode.getElement()==sName) { 
    vReturn.add(xNode); 
   }


with this:
Code:

if (sName.equals(xNode.getElement())) { 
    vReturn.add(xNode); 
   }
