Line break gone after XSLT transformation

My XML:

<root>
  <summary>
     <article_1>some data&#xA;</article_1>
  </summary>
  <summary>
     <article_1>some data&#xA;</article_1>
  </summary>
  .
  .
  .
</root>

I am trying to copy all summary tags to separate files, but when XSLT transformation is done I am loosing line breaks in the newly created files.

My XSLT:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="no" version="1.0" encoding="UTF-8" standalone="yes"/>
<xsl:template match="summary">
  <xsl:result-document href="{@summary}.xml">
    <xsl:copy-of select="." />
  </xsl:result-document>
</xsl:template>
</xsl:stylesheet>

What am I doing wrong, and why are there no line breaks in my newly created XML anymore?

I have got the variable in XSLT with the line-breaks preserved. But when transformed to HTML using XSL, line-breaks are not preserved. Then understood to use 

<pre> 
     <xsl:value-of select="$VariableName" disable-output-escaping="yes"/> 
</pre>

Now able to preserve the line breaks as it comes from the source

If your XML input uses CDATA, you can do linefeed-treatment="preserve" in your XSL

Example: XML input

<data>
  <Alert>
        <![CDATA[PredniOD
         Ca32mg Mane
         Cholenthly]]>
   </Alert>
</data>

XSL 1.0

<fo:block linefeed-treatment="preserve">
     <xsl:value-of select="data/Alert" />
 </fo:block>

Output

 PredniOD
 Ca32mg Mane
 Cholenthly

Other useful ones

white-space-collapse="false" white-space-treatment="preserve"

You do not lose any line breaks (new lines, that is), even if they appear to have vanished.

Assuming a sensible input XML:

<?xml version="1.0" encoding="utf-8"?>
<root>
  <summary number="1">
   <article_1>text1&#xA;</article_1>
  </summary>
  <summary number="2">
   <article_1>text2&#xA;</article_1>
  </summary>
  <!--...-->
</root>

And this stylesheet (this is in XSLT 2.0, as you use result-document()):

<?xml version="1.0" encoding="utf-8"?>

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

     <xsl:output method="xml" indent="no" version="1.0" encoding="UTF-8" standalone="yes"/>

     <xsl:template match="summary">
       <xsl:result-document href="{@number}.xml">
         <xsl:copy-of select="." />
       </xsl:result-document>
     </xsl:template>

</xsl:stylesheet>

This results in several output documents, like the one named 1.xml shown here:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><summary number="1">
  <article_1>text1
  </article_1>
</summary>

As you can see, there is still a new line. It is no longer encoded as an entity reference (&#xA;), but translated to an actual break. If you are looking at the result files with a browser like Firefox, it might trick you into thinking that the newlines are no longer there, but that's only formatting automatically applied by the brower's parser.

Note that your post has severe issues besides the newline problem.

  • As the name of an output XML file, you select @summary, yet in your input XML there is no such attribute. In the input I have shown there is a number attribute which is translated into the file names.
  • You are using the result-document() function that is available only in XSLT 2.0 (i.e. with an XSLT 2.0 processor). Why then is your stylesheet in version="1.0"?

The newline character is treated as white space, whether you encode it or not. You can add the directive:

<xsl:preserve-space elements="article_1"/>

to make sure that the white space is preserved.
