Can anyone please help me how to remove the first tag from a XML file using java?
Remove:
<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?">
from below XML file.
<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?">
<Tag>
<subTag>tag1</subTag>
<subTag>tag2</subTag>
</Tag>
Below code:
public class Main
{
public static void main (String args[])
{
File file= new File("XMLfile.xml");
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder db=factory.newDocumentBuilder();
Document doc=db.parse(file);
doc.getDocumentElement().normalize();
/*remove <?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?"> */
}
}
Before serialising your XML file give your doc
object to a new instance of OutputFormat
and then format.setOmitXMLDeclaration(true)
For example:
OutputFormat format = new OutputFormat(doc);
format.setIndenting(true);
format.setOmitXMLDeclaration(true);
XMLSerializer serializer = new XMLSerializer(System.out, format);
serializer.serialize(doc);
Removing the header is valid in XML 1.0, but by doing that, you will lose character encoding data and maybe other things. Please make sure that it is not going to break your system.
