xmlKeepBlanksDefault ()
int xmlKeepBlanksDefault (int val); |
Set and return the previous value for default blanks text nodes support.
+The 1.x version of the parser used an heuristic to try to detect
+ignorable white spaces. As a result the SAX callback was generating
+ignorableWhitespace() callbacks instead of characters() one, and when
+using the DOM output text nodes containing those blanks were not generated.
+The 2.x and later version will switch to the XML standard way and
+ignorableWhitespace() are only generated when running the parser in
+validating mode and when the current element doesn't allow CDATA or
+mixed content.
+This function is provided as a way to force the standard behaviour
+on 1.X libs and to switch back to the old mode for compatibility when
+running 1.X client code on 2.X . Upgrade of 1.X code should be done
+by using xmlIsBlankNode() commodity function to detect the "empty"
+nodes generated.
+This value also affect autogeneration of indentation when saving code
+if blanks sections are kept, indentation is not generated.
