Write several elments to XML by VTD-XML

Question

I want to write several elements inside one parent and I have the following code:

public void writeElement(String parent, String element, String content) {
    try {
        xmlModifier.bind(vtdNav);
        vtdNav.toElement(VTDNav.FC, parent);
        xmlModifier.insertAfterHead("<" + element + ">" + content + "</" + element + ">");
        xmlModifier.output(filepath);
    } catch (ModifyException | NavException | IOException | TranscodeException e) {
        e.printStackTrace(); 
    }
}

and calling method:

 @FXML
public void save() {
    String surname = surnameField.getText();
    String name = nameField.getText();
    String patronymic = patronymicField.getText();
    String id = idField.getText();
    String diagnosis = diagnosisArea.getText();
    String comments = commentsArea.getText();

    dbFile = DBFile.setDoc(dbDir + dbChoiceBox.getValue(), false);
    dbFile.writeElement("db", "patient", "");
    dbFile.writeElement("patient", "surname", surname);
    dbFile.writeElement("patient", "name", name);
    dbFile.writeElement("patient", "patronymic", patronymic);
    dbFile.writeElement("patient", "id", id);
    dbFile.writeElement("patient", "diagnosis", diagnosis);
    dbFile.writeElement("patient", "comments", comments);
}

but instead this result:

<db>
<patient>
<surname></surname>
<name></name>
...
</patient>
</db>

I have only this:

<db>
<patient>
<comments></comments>
</patient>
</db>

It looks like writeElement rewrite the same element each time. Why this is happening and how can I fix it?

Because you are outputting an XML file for every single modification. If you want to make all modifications all at once, you should not call XMLModifier's output every time.

Tried to exclude `xmlModifier.bind(vtdNav);` from `writeElement()` and move it into class constructor. Now I have `com.ximpleware.ModifyException: There can be only one insert per offset` exception. What is that? – Eugene Oct 02 '13 at 16:07

Yes, vtd is different from Dom in terms of modification. You are supposed to insert a single byte array per offset value. This means you have to do the text concatnatio in your code, then insert everything after an element. – vtd-xml-author Oct 03 '13 at 04:58
