Unknown xml tag extraction

Question

I have an XML document with the following structure:
<foo>
     <foo id="F1">television</foo>
     <foo id="F2">car</foo>
</foo>
foo id can be none or up to 99. So I want to extract the tag "F1", "F2", etc. and its content when it shows up in a document to enter them in separate fields in a database. I have tried different codes but with no luck. These two are my latest methods but they don't work as expected. The second method gives an error message at the line "matcher = pattern.matcher(xml)". If any one could help I would appreciate it very much.
_xmlFile is my parsed document. I know it works because I have other methods using getTextContent() with specific tags and work well.
private void processFoo(Document _xmlFile){
               String xPath = null;
               String value = null;
               xPath = "/*/foo";
               try{
                    NodeList nodelist = XPathAPI.selectNodeList(_xmlFile, xPath);
                    for(int i2 = 0; i2 < nodelist.getLength(); i2++){
                    Element elem =(Element)nodelist.item(i2);
                    value = elem.toString();
                    value = value.replaceAll("\t", "");
                    value = value.replaceAll("\n", "");
                    value = value.replaceAll("\r", "");
               }catch(TransformerException transformerexception){
               addFoo(value);
public void addFoo(String _xml)
     String regex = null;
     String id = null;
     String content = null;
     Pattern pattern = null;
     Matcher matcher = null;
     String sql = null;
     int index = 0;
     String xml = _xml;
     regex = "\\<foo id=\"F(.+?)\">";
     pattern = Pattern.compile(regex);
     matcher = pattern.matcher(xml);
     while (matcher.find())
               id = matcher.group(1);
               id = id.replaceAll("'", "");
               index = matcher.end(1)+2;
               index = xml.indexOf("</foo>", index);
               content = xml.substring(matcher.end(1)+2, index);
               content = processOfString(content);
               sql = "INSERT INTO my.Foo (Foo_Id, Foo_Content) VALUES " + "(" + id + ", '" + content + "')";
               //System.out.println(sql);
               insertQuery(sql, false);
          xml = xml.substring(index+11, xml.length());
          matcher = pattern.matcher(xml);
}

Although I still have a question (which is at the bottom) I finally got what I wanted with the following method.
private void addFoo(Document _xmlFile){
String foocontent = null;
String fooref = null;
Document doc = _xmlFile;
String foopath = "foo";
String sql = null;
NodeList foo = doc.getElementsByTagName(foopath);
for (int i = 0; i < foo.getLength(); i++){
Element foos = (Element) foo.item(i);
fooref = foos.getAttribute("id");
foocontent = foos.getTextContent();
foocontent = foocontent.replaceAll("\t", "");
footcontent = footcontent.replaceAll("\n", "");
foocontent = foocontent.replaceAll("\r", "");
//System.out.println(fooref);
//System.out.print(foocontent);
sql = "INSERT INTO insider.footnote SET fooRef = ?, fooText = ?";
try{
PreparedStatement addfoo = con.prepareStatement(sql);
addfoo.setString(1, fooref);
addfoo.setString(2, foocontent);
addfoo.executeUpdate();
}catch(SQLException ex){
System.err.println("SQLException: " + ex.getMessage());
my foo table has a primary key that I need as a foreign key in ABC table. So I was wondering if there is anything in java that would allow me to send the key to ABC every time the foo table is updated. Actually, it would better if I can store the key in a variable that I send later with other data that needs to be input into the ABC table.
Thanks.
