Re: "xmlns" problem for transform
2005-08-04 15:04:11
I solved the problem in the end in the following way :) Thanks very
very much for your great help!
-----------------------
<xsl:template match="/">
<xsl:for-each select="/*">
<xsl:choose>
<xsl:when test="namespace-uri()">
<xsl:call-template name="withschema"/>
</xsl:when>
<xsl:otherwise>
<xsl:call-template name="noschema"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</xsl:template>

xx:node-set() is the conventional way we describe a set of functions
provided by different vendors of XSLT 1.0 processors: msxml:node-set() for
MSXML, xalan:node-set() for Xalan, saxon:node-set() for Saxon,
oracle:node-set() for Oracle, etc. (Sometimes without the hyphen). Choose
the one that suits your processor. In XSLT 2.0, you don't need the function:
instead of
<xsl:apply-templates select="xx:node-set($output-of-phase-1)"/>
do
<xsl:apply-templates select="$output-of-phase-1" />
Sorry if I sometimes abbreviate my answers too much, you never know how much
knowledge the person asking the question already has, or how good they are
at looking it up if they don't know.

Dear Michael,
I can't "xx:node-set" function from both XPath 1 and XPath 2.
Problem is
still there.
cheers,

Think pipelines. First stage (optional): convert everything
to the correct
namespace. Second stage: do the real processing.
You can implement a pipeline either within a single
stylesheet or with a
series of stylesheets linked at application level. In the
first approach,
you typically do:
<xsl:variable name="output-of-phase-1">
<xsl:apply-templates select="/" mode="phase-1"/>
</xsl:variable>
<xsl:variable name="output-of-phase-2">
<xsl:apply-templates select="xx:node-set($output-of-phase-1)"
mode="phase-2"/>
</xsl:variable>
<xsl:template match="/">
<xsl:copy-of select="$output-of-phase-N"/>
</xsl:template>

You shouldn't get yourself into this situation where the
same vocabulary of
local names is used in more than one namespace. But if you
do (as RSS users
do) the best way is to write your transformation on the
assumption that the
names are in a namespace, and then write a preprocessing
transformation
where necessary to put them in that namespace. This is
essentially a variant
on the identity transform:
<xsl:template match="*[namespace-uri()='']">
<xsl:element name="{local-name()}" namespace="the.real.namespace">
<xsl:copy-of select="@*"/>
<xsl:apply-templates/>
</xsl:element>
</xsl:template>

Dear Joris:
Thank you very much! Now the problem is PARTLY solved. After
I add the
non-default namespace for my xslt filter and all needed
prefix, the
filter works well with schema assigned data files. However,
it can not
transform files without schema. An opposite problem to before.
How can I do?
cheers,

Hi,

<ccz(_at_)bao(_dot_)ac(_dot_)cn>:
it can't transform
the body of sample file with "schema" assigned.
As the post's subject indicates, this is a
namespace-related problem
indeed.
The schema sets the default namespace to
"http://www.ivoa.net/xml/VOTable/v1.1";, you need to
define in your
xslt a namespace with this uri and a chosen prefix (I know
'xmlns="http://www.ivoa.net/xml/VOTable/v1.1";' is already
present; you
need to add another non-default namespace declaration). e.g.
'xmlns:VOT="http://www.ivoa.net/xml/VOTable/v1.1";'
Next step is to find all element names in any xpath
expression or
pattern in your xslt and add the prefix.
e.g. <xsl:for-each select="//RESOURCE/TABLE/FIELD" /> becomes
<xsl:for-each select="//VOT:RESOURCE/VOT:TABLE/VOT:FIELD"/>
