I am using MSXML6 and I've set the AllowXsltScript to true in order to enable the usage of scripts in my VB program.
Given the following XML input:
<xml>
<data>
<row TEST_ATTRIBUTE_1="test1a" TEST_ATTRIBUTE_2="test2a"/>
<row TEST_ATTRIBUTE_1="test1b" TEST_ATTRIBUTE_2="test2b"/>
<row TEST_ATTRIBUTE_1="test1c" TEST_ATTRIBUTE_2="test2c"/>
</data>
</xml>
The following XSL doesn't work as expected:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version = "1.0"
xmlns:rs="urn:schemas-microsoft-com:rowset" xmlns:z="#RowsetSchema"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
xmlns:user="random">
<msxsl:script language="javascript" implements-prefix="user" >
<![CDATA[
function getValue(node, attribute)
{
var value;
value = node.getAttribute(attribute);
return value;
}
]]>
</msxsl:script>
<xsl:template match="/">
<xsl:apply-templates select="//data"/>
</xsl:template>
<xsl:template match="//data">
<TBODY>
<xsl:for-each select="row">
<xsl:value-of select="user:getValue(this, 'TEST_ATTRIBUTE_1')"/>
</xsl:for-each>
</TBODY>
</xsl:template>
</xsl:stylesheet>
The problem seems to be with passing in "this" for node inside for-each. More exactly when it's trying to do node.getAttribute(attribute);
that's when it fails.
The error I'm getting is "The text associated with this error code could not be found. XML document must have a top level element." inside Visual Studio 2017 in my VB program using the MSXML2.DOMDocument60.transformNodeToObject API.
Note that I cannot use any online XSL parsers as they have the script functionality disabled by default.
Any thoughts on this?
Appreciate it!
CodePudding user response:
It should be user:getValue(., 'TEST_ATTRIBUTE_1')
, to pass the row element node to the function; this
does not make sense in XSLT/XPath, only in Java or JavaScript or C# perhaps.
However, that the node you pass in is not reflected to the extension script as a single DOM node, you might get a DOM selection list and need e.g. function getValue(selection, attributeName) { return selection[0].getAttribute(attributeName); }
to access the first (and in this case single) item in that selection.
