Description
I need some advice, the problem might be on our side though... I have this XML:
<?xml version="1.0" encoding="UTF-8"?>
<colors>
<red>10</red>
<blue>20</blue>
<green>15</green>
</colors>
and this XSL:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="3.0">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
<svg xmlns="http://www.w3.org/2000/svg">
<xsl:apply-templates/>
</svg>
</xsl:template>
<xsl:template match="colors/*">
<circle cx="{(position() - 1) * 100}" cy="100" r="{.}"/>
</xsl:template>
</xsl:stylesheet>
For the Oxygen debugger we serialize the XML using the net.sf.saxon.event.ComplexContentOutputter class with a serializer. The resulting output is this one:
<?xml version="1.0" encoding="UTF-8"?>
<svg xmlns="http://www.w3.org/2000/svg">
<circle cx="100" cy="100" r="10"/>
<circle cx="300" cy="100" r="20"/>
<circle cx="500" cy="100" r="15"/>
</svg>
which is incorrect because the "circle" element should have an empty xmlns="" set on it.
Lookin at the callbacks we receive in our content handler, we do not receive a startPrefixMapping("", "") before the startElement("circle") is received.
Looking at the code here: net.sf.saxon.event.ComplexContentOutputter.startContent() it does something like this:
if (pendingStartTag.hasURI("") && !pendingNSMap.getDefaultNamespace().isEmpty()) {
pendingNSMap = pendingNSMap.remove("");
}
but I'm not sure it is to blame for the problem.
