Hello all,
I can't seem to get XPATH to work properly. The only thing I've been
able to select is the root node.
Any help is much apreciated.
Thanks,
--Evan
Here's my HTML, code, and input/output. I think I must be doing
something fundamentally wrong, but can't seem to spot it.
test.html:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>
<html>
<head>
<title>Title</title>
<style>
body{
background: blue;
}
</style>
</head>
<body>
<div id="main">
HI!
</div>
</body>
</html>
CODE:(note: args[0] is the file, args[1] is the XPath expression)
Document doc = DOM.getCachedDocument(args[0]);
Element root = doc.getRootElement();
List l = root.selectNodes(args[1]);
if(l.size() > 0){
Element elem = (Element)l.get(0);
Element p = elem.addElement("p");
p.setText("hi");
}else{
System.out.println(" NO MATCHES! ");
}
DOM.print( doc, new PrintWriter(System.out, true) );
TRIES:
./run.sh test.html /html/body
NO MATCHES!
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml";>
<head>
<title>Title</title>
<style xml:space="preserve">
body{
background: blue;
}
</style>
</head>
<body>
<div id="main">
HI!
</div>
</body>
</html>
./run.sh test.html *
NO MATCHES!
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml";>
<head>
<title>Title</title>
<style xml:space="preserve">
body{
background: blue;
}
</style>
</head>
<body>
<div id="main">
HI!
</div>
</body>
</html>
This one works:
./run.sh test.html .
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml";>
<head>
<title>Title</title>
<style xml:space="preserve">
body{
background: blue;
}
</style>
</head>
<body>
<div id="main">
HI!
</div>
</body>
<p>hi</p>
</html>
I don't really understand this either. If the context node doesn't
throw this, why would the root node?
./run.sh test.html /
java.lang.ClassCastException
