[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] should be a simple problem
 I am new to xslt. Much of the explanation of xslt (books, websites) discuss
namespace from the .xsl perspective and doesn't give examples where the -IN
xml document uses namespaces. My specific problem is that when I add a
namespace, the examples break. Here is a simple Michael Kay example:
First without namespace (works fine):
opera.xml
-----------
<?xml version="1.0"?>
<programme>
<opera>
<title>The Magic Flute</title>
<composer>Mozart</composer>
<date>1791</date>
</opera>
<opera>
<title>Don Giovanni</title>
<composer>Mozart</composer>
<date>1787</date>
</opera>
<opera>
<title>Ernani</title>
<composer>Verdi</composer>
<date>1843</date>
</opera>
<opera>
<title>Rigoletto</title>
<composer>Verdi</composer>
<date>1850</date>
</opera>
<opera>
<title>Tosca</title>
<composer>Puccini</composer>
<date>1897</date>
</opera>
<composer name="Mozart">
<fullname>Wolfgang Amadeus Mozart</fullname>
<born>1756</born>
<died>1791</died>
</composer>
<composer name="Verdi">
<fullname>Guiseppe Verdi</fullname>
<born>1813</born>
<died>1901</died>
</composer>
<composer name="Puccini">
<fullname>Giacomo Puccini</fullname>
<born>1858</born>
<died>1924</died>
</composer>
</programme>
-----------
opera.xsl
-----------
<html
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xsl:version="1.0">
<body><center>
<h1>Programme</h1>
<xsl:for-each select="/programme/composer">
<h2><xsl:value-of select="concat(fullname, ' (', born, '-', died,
')')"/></h2>
<xsl:variable name="c" select="."/>
<xsl:for-each select="/programme/opera[composer=$c/@name]">
<p><xsl:value-of select="title"/></p>
</xsl:for-each>
</xsl:for-each>
</center></body>
</html>
-----------
RUN
C:\xml>java org.apache.xalan.xslt.Process -IN opera.xml -XSL opera.xsl -OUT
oper
a.out2 -TS
PRODUCES
-----------
<html>
<body>
<center>
<h1>Programme</h1>
<h2>Wolfgang Amadeus Mozart (1756-1791)</h2>
<p>The Magic Flute</p>
<p>Don Giovanni</p>
<h2>Guiseppe Verdi (1813-1901)</h2>
<p>Ernani</p>
<p>Rigoletto</p>
<h2>Giacomo Puccini (1858-1924)</h2>
<p>Tosca</p>
</center>
</body>
</html>
-----------
NOW ADD A NAMESPACE
-----------
opera.xml
-----------
<?xml version="1.0"?>
<programme xmlns="http://www.emilygraham.com/java/other/Opera">
........everything else is the same
</programme>
-----------
with SAME xsl file
-----------
-----------
RUN
C:\xml>java org.apache.xalan.xslt.Process -IN opera.xml -XSL opera.xsl -OUT
oper
a.out2 -TS
PRODUCES
-----------
<html>
<body>
<center>
<h1>Programme</h1>
</center>
</body>
</html>
-----------
This is the crux of the problem....i just don't know why; the -TS on xalan
Process.class gives (with Namespace):
C:\xml>java org.apache.xalan.xslt.Process -IN opera.xml -XSL opera.xsl -OUT
oper
a.out2 -TS
file:///C:/xml/opera.xsl Line #7, Column #47: for-each, select='null':
[empty node list]
----------
WHILE without the namespace you get this:
C:\xml>java org.apache.xalan.xslt.Process -IN opera.xml -XSL opera.xsl -OUT
oper
a.out2 -TS
file:///C:/xml/opera.xsl Line #7, Column #47: for-each, select='null':
10040: composer
1004d: composer
1005a: composer
file:///C:/xml/opera.xsl Line #8, Column #81: value-of,
select='concat(fullname,
' (', born, '-', died, ')')': Wolfgang Amadeus Mozart (1756-1791)
file:///C:/xml/opera.xsl Line #9, Column #43: variable, select='.':
10040: composer
file:///C:/xml/opera.xsl Line #10, Column #67: for-each, select='null':
10004: opera
10010: opera
file:///C:/xml/opera.xsl Line #11, Column #45: value-of, select='title':
10006: title
file:///C:/xml/opera.xsl Line #11, Column #45: value-of, select='title':
10012: title
file:///C:/xml/opera.xsl Line #8, Column #81: value-of,
select='concat(fullname,
' (', born, '-', died, ')')': Guiseppe Verdi (1813-1901)
file:///C:/xml/opera.xsl Line #9, Column #43: variable, select='.':
1004d: composer
file:///C:/xml/opera.xsl Line #10, Column #67: for-each, select='null':
1001c: opera
10028: opera
file:///C:/xml/opera.xsl Line #11, Column #45: value-of, select='title':
1001e: title
file:///C:/xml/opera.xsl Line #11, Column #45: value-of, select='title':
1002a: title
file:///C:/xml/opera.xsl Line #8, Column #81: value-of,
select='concat(fullname,
' (', born, '-', died, ')')': Giacomo Puccini (1858-1924)
file:///C:/xml/opera.xsl Line #9, Column #43: variable, select='.':
1005a: composer
file:///C:/xml/opera.xsl Line #10, Column #67: for-each, select='null':
10034: opera
file:///C:/xml/opera.xsl Line #11, Column #45: value-of, select='title':
10036: title
Can someone explain what you do differently when an element comtains a
namespace?
Thanks
Tom
