Output method html not closing empty tags
Hi,
We have an externally generated XSLT which we use for a transformation using Xalan.
The result however is not as expected.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fn="http://www.w3.org/2005/xpath-functions" xmlns:link="http://www.xbrl.org/2003/linkbase" xmlns:xbrldi="http://xbrl.org/2006/xbrldi" xmlns:xbrli="http://www.xbrl.org/2003/instance" xmlns:xdt="http://www.w3.org/2005/xpath-datatypes" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" exclude-result-prefixes="fn link xbrldi xbrli xdt xlink xs xsi">
<xsl:output version="4.0" method="html" indent="no" encoding="UTF-8" doctype-public="-//W3C//DTD HTML 4.01 Transitional//EN" doctype-system="http://www.w3.org/TR/html4/loose.dtd"/>
<xsl:param name="SV_OutputFormat" select="'HTML'"/>
<xsl:variable name="XML" select="/"/>
<xsl:template match="/">
<html>
<body style="margin-left=0.6in; margin-right=0.6in; margin-top=0.79in; margin-bottom=0.79in">
<img>
<xsl:attribute name="src">
<xsl:text>file:///</xsl:text>
</xsl:attribute>
</img>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
This results in the following output:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html xmlns:altova="http://www.altova.com"><body style="margin-left=0.6in; margin-right=0.6in; margin-top=0.79in; margin-bottom=0.79in"><img src="file:///"></body></html>
As you can see the <img/> tag is not well formed, and we'd like to have XHTML.
The result is OK when we use <xsl:output method="xml" />, but we don't have control over the stylesheet.
I drilled it down to line 1011 of ./trunk/src/org/apache/xml/serializer/ToHTMLStream.java
What's the reason for this not to be:
writer.write('/>');
?
Thanks,
Brecht
Re: Output method html not closing empty tags
Posted by ke...@us.ibm.com.
I believe this is correct HTML output. HTML tags can often be implicitly
closed, since HTML is based on SGML.
If you want things explicitly closed, you want XML or XHTML output.
Unfortunately, XHTML support isn't available in Xalan at this time; it's
only a standard feature in XSLT 2.0, and Xalan is a 1.0 processor. So the
best advice I can give you is to select XML if you want the document to
look more like XHTML (and be well-formed XML), or HTML if you want the
document to be HTML (which is not required to be well-formed XML).

Output method html not closing empty tags
Hi,
We have an externally generated XSLT which we use for a transformation
using Xalan.
The result however is not as expected.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="
http://www.w3.org/1999/XSL/Transform" xmlns:fn="
http://www.w3.org/2005/xpath-functions" xmlns:link="
http://www.xbrl.org/2003/linkbase" xmlns:xbrldi="
http://xbrl.org/2006/xbrldi" xmlns:xbrli="
http://www.xbrl.org/2003/instance" xmlns:xdt="
http://www.w3.org/2005/xpath-datatypes" xmlns:xlink="
http://www.w3.org/1999/xlink" xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
exclude-result-prefixes="fn link xbrldi xbrli xdt xlink xs xsi">
<xsl:output version="4.0" method="html" indent="no"
encoding="UTF-8" doctype-public="-//W3C//DTD HTML 4.01 Transitional//EN"
doctype-system="http://www.w3.org/TR/html4/loose.dtd"/>
<xsl:param name="SV_OutputFormat" select="'HTML'"/>
<xsl:variable name="XML" select="/"/>
<xsl:template match="/">
<html>
<body
style="margin-left=0.6in; margin-right=0.6in; margin-top=0.79in;
margin-bottom=0.79in">
<img>
<xsl:attribute name="src">
<xsl:text>file:///</xsl:text>
</xsl:attribute>
</img>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
This results in the following output:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "
http://www.w3.org/TR/html4/loose.dtd">
<html xmlns:altova="http://www.altova.com"><body style="margin-left=0.6in;
margin-right=0.6in; margin-top=0.79in; margin-bottom=0.79in"><img src="
file:///"></body></html>
As you can see the <img/> tag is not well formed, and we'd like to have
XHTML.
The result is OK when we use <xsl:output method="xml" />, but we don't
have control over the stylesheet.
I drilled it down to line 1011 of
./trunk/src/org/apache/xml/serializer/ToHTMLStream.java
What's the reason for this not to be:
writer.write('/>');
?
Thanks,
Brecht

Hi,
I have experienced something similar.
I had
<tag>
<xsl:choose>
.....
</xsl:choose>
</tag>
In the situations where no output was generated between <tag> and </tag>
then Xalan would suppress writing </tag> to the result tree.
I fixed those specific situations by adding:
<xsl:text> </xsl:text>
before just before </tag>
Best regards
