[libxml++] ignore empty text nodes

[Andrej van der Zee <andrejvanderzee gmail com>]

Hi,

I am a happy user of libxmlpp for some time now. One thing I could not
find out yet. How can I ignore empty text nodes? The problem is that I
construct a dom document by reading two XML files and merging them
together with import_node(). I also remove some nodes manually with
remove_child(). Finally I do a doc->write_to_stream_formatted(cout,
"UTF-8") and end up with ugly output with holes in them like this:

<?xml version="1.0" encoding="UTF-8"?>
<session xmlns="XXX" version="1.0" clientName="Belastingdienst"
projectName="GBV" phase="1" iteration="1" sessionName="M2 - AUTO
TEST3">
  <hosts>
    <host name="apmvsq1" cluster="apmvsp1+2" type="mainframe"

cpuSpeedBenchmark="MIPS" cacheHitPerc="95" cacheHitTime="0.0015"
cacheMissTime="0.005" monitoringTool="ascb" timeDiff="67"/>

I understand that these are empty text-nodes, but I wish to ignore
them. How can I do that without writing my own version of
write_to_stream_formatted()? I just wish to ignore them altogether.

Thank you,
Andrej
