Hello, It would be nice to have following functions in API:
getNextToken(tokenType); getNextSiblingToken(tokenType); etc -----Original Message----- From: Lawrence Jones [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 28, 2006 1:51 AM To: [email protected] Subject: RE: Help needed with mixed content... Hi Pavel The trouble with mixed content is that text can occur mixed in any order with element content. Exactly how the user wants to use that differs from user to user - which is why XmlBeans provides the more general XmlCursor API that the user can use to do whatever they want (and more specifically is why there is no general "getText()" method on every generated bean - as there was no agreement as to which bits of text this should return). If pointed at an ELEM token getTextValue() will return you the text from all of the individual text tokens (both for its own text content and its children's) concatenated together. This is OK if you are sure that the element will contain _only_ text or children (you could use the toFirstChild() API to check whether it has any children). But you're right, in more complicated cases it's not enough. You can also navigate individually to each TEXT token (at the correct depth if that is what you want) e.g. using TokenType.isText() - then getTextValue() will return you the text for just that token (your use of getChars() will work too since you are pointing only at TEXT tokens). But your code looks fine. If you want to separate out the different parts of text, you could always put each text value in a List instead of concatenating them together - but whatever suits your application. I'm not sure what else you need?
