When I try to
parse a XML-file, it gives sometimes a null element by the title.
I think it has to do with HTML-tags '
How can I solve this problem?
I have the follow XML-file:
<item>
<title>' Nieuwe DVD '</title>
<description>tekst, tekst tekst</description>
<link>dvd.html</link>
<category>nieuws</category>
<pubDate>Sat, 1 Jan 2011 9:24:00 +0000</pubDate>
</item>
And the follow code to
parse the xml-file:
//DocumentBuilderFactory, DocumentBuilder are used for
//xml parsing
DocumentBuilderFactory dbf = DocumentBuilderFactory
.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
//using db (Document Builder)
parse xml data and assign
//it to Element
Document document = db.parse(is);
Element element = document.getDocumentElement();
//take rss nodes to NodeList
element.normalize();
NodeList nodeList = element.getElementsByTagName("item");
if (nodeList.getLength() > 0)
{
for (int i = 0; i < nodeList.getLength(); i++)
{
//take each entry (corresponds to <item></item> tags in
//xml data
Element entry = (Element) nodeList.item(i);
entry.normalize();
Element _titleE = (Element) entry.getElementsByTagName(
"title").item(0);
Element _categoryE = (Element) entry
.getElementsByTagName("category").item(0);
Element _pubDateE = (Element) entry
.getElementsByTagName("pubDate").item(0);
Element _linkE = (Element) entry.getElementsByTagName(
"link").item(0);
String _title = _titleE.getFirstChild().getNodeValue();
String _category = _categoryE.getFirstChild().getNodeValue();
Date _pubDate = new Date(_pubDateE.getFirstChild().getNodeValue());
String _link = _linkE.getFirstChild().getNodeValue();
//create RssItemObject and add it to the ArrayList
RssItem rssItem = new RssItem(_title, _category, _pubDate, _link);
rssItems.add(rssItem);
conn.disconnect();
}
