Dear Stefan!
So: may I don't understand the things well, but I thought that parser drop the "nondata" CRLF-s + other characters (not preserve them). Then don't matters that I read the XML from a file, or I create it from code, because all of them generating SAME RESULT. But Python don't do that. If I make xml from code, the code is without plus characters. But Python preserves parsed CRLF characters somewhere, and they are also flushing into the result. Example: original=''' <?xml version="1.0" encoding="utf-8"?> <doc a="1"> <element a="1"> AnyText </element> </doc> ''' If I parse this, and write with toxml, the CRLF-s remaining in the code, but if I create this document line by line, there is no CRLF, the toxml write "only lined" xml. This also meaning that if I use prettyxml call, to prettying the xml, the file size is growing. If there is a multiple processing queue - if two pythons communicating in xml files, the size can growing every time. Py1 - read the Py2's file, process it, and write to a result file Py2 - read the Py1's result file, process it, and pass back to Py1 this can grow the file with each call, because "pretty" CRLF-s not normalized out from the code. original=''' <?xml version="1.0" encoding="utf-8"?> <doc a="1"> <element a="1"> AnyText </element> </doc> ''' def main(): f = open('test.0.xml','w') f.write(original.strip()) f.close() for i in range(1, 10 + 1): xo = parse('test.%d.xml' % (i - 1)) de = xo.documentElement de.setAttribute('c', str(i)) t = de.getElementsByTagName('element')[0] tn = t.childNodes[0] print (dir(t)) print (tn) print (tn.nodeValue) tn.nodeValue = str(i) + '\t' + '\n' #s = xo.toxml() s = xo.toprettyxml() f = open('test.%d.xml' % i,'w') f.write(s) f.close() sys.exit() And: because Python is not converting CRLF to &013; I cannot make different from "prettied source's CRLF" (loaded from template file), "my own pretty's CRLF" (my own topretty), and really contained CRLF (for example a memo field's value). My case is that the processor application (for whom I pass the XML from Python) is sensitive to "plus CRLF"-s in text nodes, I must do something these "plus" items to avoid external's program errors. I got these templates and input files from prettied format (with CRLFS), but I must "eat" them to make an XML that one lined if possible. I hope you understand my problem with it.
