I am using Oxygen Author and trying to establish how to control the presence or absence of line breaks where I want them in a text file generated by applying an XSLT transformation to an XML file.

The XML is as follows:

Code: Select all

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

<!DOCTYPE l1 SYSTEM "Simple.dtd">

<?xml-stylesheet type="text/xsl" href="Simple2.xsl"?>

<l1><l2><l3>1a</l3><l3>1b</l3><l3>1c</l3>

</l2>

<l2>

<l3>2a</l3><l3>2b</l3><l3>2c</l3>

</l2>

<l2>

<l3>3a</l3>

<l3>3b</l3>

<l3>3c</l3>

</l2>

</l1>

I want both this and the following (which is equivalent, without the linebreaks) to produce the same result from any transformation.

Code: Select all

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

<!DOCTYPE l1 SYSTEM "Simple.dtd">

<?xml-stylesheet type="text/xsl" href="Simple2.xsl"?>

<l1><l2><l3>1a</l3><l3>1b</l3><l3>1c</l3></l2><l2><l3>2a</l3><l3>2b</l3><l3>2c</l3></l2><l2><l3>3a</l3><l3>3b</l3><l3>3c</l3></l2></l1>

Can anyone help? I've tried the following stylesheet but it produces different results for the two inputs.

Code: Select all

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

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

<xsl:output method="text" encoding="utf-8" />

<xsl:template match="/"><xsl:apply-templates/></xsl:template><xsl:template match="l1"><xsl:apply-templates/></xsl:template><xsl:template match="l2"><xsl:apply-templates/></xsl:template><xsl:template match="l3"><xsl:value-of select="."/></xsl:template> 

</xsl:stylesheet>

How can I control whether I get:

Code: Select all

1a1b1c2a2b2c3a3b3c

or

Code: Select all

1a1b1c

2a2b2c

3a3b3c

or

Code: Select all

1a

1b

1c

2a

2b

2c

3a

3b

3c

regardless of whether there are linebreaks or spaces in the input XML?

You get the text nodes copied to the output by the built in rules. Adding

<xsl:template match="text()"/>

will give you always the 1a1b1c2a2b2c3a3b3c result.

OK, where should I add it? And what about the other two results?

Thanks!

You need to add that to your stylesheet:

Code: Select all


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

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

  <xsl:output method="text" encoding="utf-8"/>

  <xsl:template match="/">

    <xsl:apply-templates/>

  </xsl:template>

  <xsl:template match="l1">

    <xsl:apply-templates/>

  </xsl:template>

  <xsl:template match="l2">

    <xsl:apply-templates/>

  </xsl:template>

  <xsl:template match="l3">

    <xsl:value-of select="."/>

  </xsl:template>

  <xsl:template match="text()"/>

</xsl:stylesheet>

In order to get
1a1b1c
2a2b2c
3a3b3c

you need to emit a new line at the end of processing l2 elements:

Code: Select all


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

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

  <xsl:output method="text" encoding="utf-8"/>

  <xsl:template match="/">

    <xsl:apply-templates/>

  </xsl:template>

  <xsl:template match="l1">

    <xsl:apply-templates/>

  </xsl:template>

  <xsl:template match="l2">

    <xsl:apply-templates/>

    <xsl:text>&#10;</xsl:text>

  </xsl:template>

  <xsl:template match="l3">

    <xsl:value-of select="."/>

  </xsl:template>

  <xsl:template match="text()"/>

</xsl:stylesheet>

and to get

1a
1b
1c
2a
2b
2c
3a
3b
3c

you need to output the new line after you process each l3 element

Code: Select all


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

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

  <xsl:output method="text" encoding="utf-8"/>

  <xsl:template match="/">

    <xsl:apply-templates/>

  </xsl:template>

  <xsl:template match="l1">

    <xsl:apply-templates/>

  </xsl:template>

  <xsl:template match="l2">

    <xsl:apply-templates/>

  </xsl:template>

  <xsl:template match="l3">

    <xsl:value-of select="."/>

    <xsl:text>&#10;</xsl:text>

  </xsl:template>

  <xsl:template match="text()"/>

</xsl:stylesheet>

Thanks. It's amazing none of the online tutorials mentions this.
