Please find below some excerpts from the new sample that we have
added to Xerces-C. It illustrates how you can create a DOM tree
in memory. Note: It uses DOM Level 2 api's to create the
document node.
The next binary release of Xerces-C 1.1.0 will contain this sample.
If you need it today, then you could download the snapshot of the
repository and compile it.
We hope to publish the next binary release in about two weeks.
