The motivation for this function is to allow to parse consistently both empty elements and elements that has non empty content, for example for input:
p.nextTag() p.requireEvent(p.START_TAG, "", "tag"); String content = p.nextText(); p.requireEvent(p.END_TAG, "", "tag");This function together with nextTag make it very easy to parse XML that has no mixed content.
Essentially it does this
if(getEventType() != START_TAG) { throw new XmlPullParserException( "parser must be on START_TAG to read next text", this, null); } int eventType = next(); if(eventType == TEXT) { String result = getText(); eventType = next(); if(eventType != END_TAG) { throw new XmlPullParserException( "event TEXT it must be immediately followed by END_TAG", this, null); } return result; } else if(eventType == END_TAG) { return ""; } else { throw new XmlPullParserException( "parser must be on START_TAG or TEXT to read text", this, null); }
