Hi objects,<br />
how to use xsl that you have given to the XML document i have?<br />
<br />
CEHJ,<br />
I am using the following code, it is not printing anything. Even it isn't printing &quot;&nbsp;XML Request for Thread name is:&quot;<br />
<br />
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;org.jdom.Document XMLDocreq = null;<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;SAXBuilder builder = new SAXBuilder();<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;XMLOutputter xout = new XMLOutputter(Format.getCom<wbr />pactFormat<wbr />());<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;XMLDocreq = builder.build(new InputSource(new StringReader(xmlReq)));<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;System.out.println(&quot;XML Request for &quot;+Thread.currentThread().g<wbr />etName()+&quot;<wbr />is :&quot;);<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; System.out.println(xout.ou<wbr />tputString<wbr />(XMLDocreq<wbr />)); // no superfluous whitespace<br />
<br />
Please suggest.
</div>


<div>
&gt;&gt;Even it isn't printing &quot;&nbsp;XML Request for Thread name is:&quot;<br />
<br />
Make sure you have no uncaught/ignored exceptions
</div>


<div>
You are right CEHJ,<br />
<br />
It is giving an error in SysErr.log file<br />
java.lang.NoClassDefFoundE<wbr />rror: org/jdom/output/Format<br />
<br />
But, I already have <br />
&quot;jaxen-core.jar&quot; &quot;jaxen-jdom.jar&quot; &quot;jdom.jar&quot; &quot;saxpath.jar&quot; &quot;xalan.jar&quot; &quot;xerces.jar&quot; &quot;xml-apis.jar&quot; in my build path of the project. <br />
<br />
And what is weird is that &quot;It would have given compilation error if it isn't present in the project. But it is giving the runtime error saying NoClassDefFoundError Format.&quot; Please suggest why is this happening. 
</div>

CEHJ,<br />
I think your solution will give me compact unformatted xml. So, i am closing this and opening another question for the above problem since this problem is irrelevant to the question. Please find the link below.<br />
Thanks for your time<br />
<br />
And also Thanks objects.<br />

i wouldn't be so sure, that method is known to *not* remove all white space<br />
<br />
<br />

</div>


<div>
objects,<br />
It &quot;is&quot; removing all the whitespace for me. Thanks for your concern though. Your comments are appreciated.
</div>


<div>
thats good. We've had cases where it both leaves some, and also even *adds* extra whitespace so beware. Thats why we always use a transformation as it is more reliable.<br />

<div class="content wysiwyg-content">
I have xml request in formatted manner in a String. It is taking up a lot of space in the server logs.<br />
like <br />
&lt;req&gt;<br />

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;element2&gt;<br />

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;/element1&gt;<br />
&lt;/req&gt;<br />
<br />
I want this to be of the form &lt;req&gt;&lt;element1&gt;&lt;element2&gt;&lt;<wbr />/element2&gt;<wbr />&lt;/element1<wbr />&gt;&lt;/req&gt; without formatting and should be fast.

Unformatting xml

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.

Java

Extensible Markup Language (XML) refers to the encoding of documents such that they can be read by both machines and humans. XML documents use tags to show the beginning and end of a set of data. XML is used extensively on websites to show volumes of data, and is the default for a number of office productivity suites. This topic includes discussions of XML-related technologies, such as XQuery (the XML Query language), XPath (the XML Path language), XSLT (eXtensible Stylesheet Language Transformations), XLink (the XML Linking language) and XPointer (the XML Pointer language).
