Re: [xmlc] Adding xhtml code in string form: msg#00035 java.enhydra.xmlc

I figured I should contribute SOMETHING to this list
that I've gotten so much out of. I hate googling for
a problem and finding an email list archive where the
person just says, "Nevermind, I've figured it out,"
without posting the solution. Jerks! :-)

To be honest, the solution I posted doesn't quite
work. The correct solution is this:

---
// same imports as previous message

public static final String XML_HEADER = "<?xml
version=\"1.0\" encoding=\"ISO-8859-1\"?>\n";

public static final void addXhtmlToNode(final
XMLObject page, final Node destNode, final String src)
throws IOException, SAXException
{
final StringBuilder xml = new
StringBuilder(XML_HEADER);
xml.append("");
xml.append(src);
xml.append("");
final DOMParser parser = new DOMParser();
parser.parse(new InputSource(new
ByteArrayInputStream(xml.toString().getBytes())));
final Document document = parser.getDocument();
final NodeList nodeList =
document.getFirstChild().getChildNodes();
for (int i = 0; i < nodeList.getLength(); i++)

destNode.appendChild(page.importNode(nodeList.item(i),
true));
}
---

The differences:

1) Leave out the xhtml part of the header, because it
requires an <html> tag.
2) The magic around the xhtml string. This
will allow for xhtml code that doesn't start with a
tag, like "This is some bold text". It worked
before for my unordered list because my xhtml code
started with a <ul> tag.

May your time be saved by this example!

P.S. What kind of idiot made the NodeList class that
doesn't implement any java.util collection interfaces?
Would an iterator() method have been so hard? I
mean, getLength() and item()???
