R XML package weird bug while parsing xml and html files

[Sezar]

I am using R's XML package to extract all possible data over a wide variety of html and xml files. These files are basically documentation or build properties or readme file.\[code\]<?xml version='1.0' encoding='utf-8'?><!DOCTYPE chapter PUBLIC '-//OASIS//DTD DocBook XML V4.1.2//EN' 'http://www.oasis-open.org/docbook/xml/4.0 docbookx.dtd'><chapter lang="en"><chapterinfo><author><firstname>Jirka</firstname><surname>Kosek</surname></author><copyright><year>2001</year><holder>Ji&rcaron;&iacute; Kosek</holder></copyright><releaseinfo>$Id: htmlhelp.xml,v 1.1 2002/05/15 17:22:31 isberg Exp $</releaseinfo></chapterinfo><title>Using XSL stylesheets to generate HTML Help</title><?dbhtml filename="htmlhelp.html"?><para>HTML Help (HH) is help-format used in newer versions of MSWindows and applications written for this platform.

If there are child nodes at level 2 or more, the text fields get pasted without any space in between them.For example, in the above examplexmlValue(chapterInfo) is \[code\]JirkaKosek2001JiKosek$Id: htmlhelp.xml,v 1.1 2002/05/15 17:22:31 isberg Exp \[/code\]The xmlValues of each child node (recursive) is pasted together without adding space between them. How can I get xmlValue to add a whitespace while extracting this dataThanks a lot for your help in advance,Shivani
