Trying to solve an issue for someone else and instead have run into my own odd issue which I am sure is simple yet the answer is eluding me!

The XML I have:

<xml>
  <head>
    <info>
      <content>
        <source attribute1="RSC1985s5c1" attribute2="6(17)">
          data1
        </source>
        <cite/>
        <case/>
        (
        <target attribute1="LRC1985s5c1" attribute2="6(17)1">
          3e/191
        </target>
        )
      </content>
      <content>
        <source attribute1="RSC1985s5c1" attribute2="6(17)">
          data2
        </source>
        <cite/>
        <case/>
        (
        <target attribute1="LRC1985s5c4" attribute2="6(17)1">
          4e/54
        </target>
        )
      </content>
    </info>
  </head>
</xml>

With XSLT to combine the two content elements:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

  <xsl:template match="node() | @*">
    <xsl:copy>
      <xsl:apply-templates select="@*"/>
      <xsl:apply-templates select="node()"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="info">
    <xsl:copy>
      <xsl:element name="content">
        <xsl:for-each select="content">
          <xsl:apply-templates select="@*"/>
          <xsl:apply-templates select="node()"/>
        </xsl:for-each>
      </xsl:element>
    </xsl:copy>
  </xsl:template>

</xsl:stylesheet>

This creates:

<?xml version="1.0" encoding="utf-8"?><xml> //Just noticed here too!
  <head>
    <info><content> //Why no new line here?
        <source attribute1="RSC1985s5c1" attribute2="6(17)">
          data1
        </source>
        <cite />
        <case />
        (
        <target attribute1="LRC1985s5c1" attribute2="6(17)1">
          3e/191
        </target>
        )

        <source attribute1="RSC1985s5c1" attribute2="6(17)">
          data2
        </source>
        <cite />
        <case />
        (
        <target attribute1="LRC1985s5c4" attribute2="6(17)1">
          4e/54
        </target>
        )
      </content></info> //And again here?
  </head>
</xml>

The issue highlighted using commenting is what I cannot figure out, why there is no new line between the elements.

Thanks in advance.

    With the provided transformation slightly modified:

    <xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

  <xsl:template match="node() | @*">
    <xsl:copy>
      <xsl:apply-templates select="@*"/>
      <xsl:apply-templates select="node()"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="info">
    <xsl:copy>
      <xsl:element name="content">
        <xsl:for-each select="content">
          <xsl:apply-templates select="@*"/>
          <xsl:apply-templates select="node()"/>
        </xsl:for-each>
      </xsl:element>
    </xsl:copy>
  </xsl:template>
</xsl:stylesheet>

    I get with Saxon 6.5.5 and a number of other XSLT 1.0 processors a well-indented output:

    <xml>
   <head>
      <info>
         <content>
            <source attribute1="RSC1985s5c1" attribute2="6(17)">
          data1
        </source>
            <cite/>
            <case/>
        (
        <target attribute1="LRC1985s5c1" attribute2="6(17)1">
          3e/191
        </target>
        )
      <source attribute1="RSC1985s5c1" attribute2="6(17)">
          data2
        </source>
            <cite/>
            <case/>
        (
        <target attribute1="LRC1985s5c4" attribute2="6(17)1">
          4e/54
        </target>
        )
      </content>
      </info>
   </head>
</xml>

    Some XSLT processors may still produce unwanted-indentation — there is no strict standard in the W3C XSLT 1.0 recommendation how exactly indentation should be performed.
