I am trying to do a split of String array at the i th location. with a regex for 4 or more spaces.

i found a lot of information here and other sites, hence I came up with 

```
String[] parts = titlesAuthor[i].split("    ");

```

so the split can happen between the title and authors name which contains either 4 or more spaces or does not exist as all.

Example: 

```
titleAuthor[0] = Investigational drugs for autonomic dysfunction in Parkinson's disease          Perez-Lloret S

```

After running the above split, parts[0] is coming up as empty and part[1] has the complete string.

please help!

code :

```
for (int i = 0; i < nodes.getLength(); i++) { Element element = (Element) nodes.item(i); NodeList title = element.getElementsByTagName("TEXT"); line = (Element) title.item(0); titlesAuthor[i] = getCharacterDataFromElement(line); System.out.println(titlesAuthor[i]); parts = titlesAuthor[i].split(" "); System.out.println(parts[0]); System.out.println(parts[1]); } 

```
