urban_man :
Hi I'm using dom to parse xml files mostly through the use of getTextContent, but for some reason I can't get the text from the picture tag and I'm not sure why
public String image(){
{
try {
builder = factory.newDocumentBuilder();
Document doc= builder.parse(filename);
NodeList messageList=doc.getElementsByTagName("picture");
for(int i=0;i<messageList.getLength();i++){
Node node=messageList.item(i);
if(node.getNodeType()==Node.ELEMENT_NODE){
Element element=(Element) node;
System.out.println(element.getTextContent());
}
}
} catch (ParserConfigurationException e) {
e.printStackTrace();
} catch (SAXException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
return "error";
}
this is an example xml file
<?xml version="1.0" encoding="UTF-8"?>
<test>
<text>can't get picture tag to work zzz</text>
<picture data="iVBORw0KGgoAAAANSUhEUgAAKXRFWHRDcAAHdElNRQfk6CIIiPoZwD+ALXGFxj6BgYeU7BO4tToSDFHYWZ2+/c03OzPZDRJNYcgVwG4hZQOLPeF24ZkCe6ZxDCOqHcmxmsr+hsicahss+n8vYb8NHZPTJxi/RGC5IqbRwqH6uxVTX+5LvHtvT/V/R6PGh/iF4GHoBAwz7RD26spwq6Amh/AAAAAElFTkSuQmCC" />
</test>

That's because you are trying to get content of the empty tag. What you want is the value of the data
attribute, which can be obtained as follows:
element.getAttributes().getNamedItem("data").getNodeValue()
