Empty element tags not compatible with result-document ixsl methods
0%
Description
Using ixsl:replace-content or ixsl:append-content does not work with short-form empty element tags, i.e. <div id="shortformEmptyDiv"/>. I would be surprised if this is not already known, but here is an example:
index.html
<!DOCTYPE html>
<html
xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Bug Demo</title>
<script src="js/Saxon-JS-1.2.0/SaxonJS.min.js"></script>
<script type="text/javascript">
window.onload = function() {
SaxonJS.transform({
stylesheetLocation: "bug.sef.xml",
initialTemplate: "Q{http://www.w3.org/1999/XSL/Transform}initial-template",
});
}
</script>
</head>
<body>
<div id="longformEmptyDiv"></div>
<div>Here is some placeholder content.</div>
<div id="shortformEmptyDiv"/>
<div>Here is some placeholder content.</div>
<div id="disappearingAct"></div>
<div>Here is some placeholder content.</div>
</body>
</html>

<xsl:result-document href="?." method="ixsl:replace-content">

</xsl:result-document>
</xsl:template>
<xsl:template
match="div[@id='longformEmptyDiv']">

</xsl:result-document>

<xsl:template

<xsl:result-document href="?." method="ixsl:replace-content">
<p>Here is some disappearingAct content.</p>
</xsl:result-document>
</xsl:template>
</xsl:transform>
browser result:
<html
xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Bug Demo</title>
<script src="js/Saxon-JS-1.2.0/SaxonJS.min.js"></script>
<script type="text/javascript">
window.onload = function() {
SaxonJS.transform({
stylesheetLocation: "xsl/bug.sef.xml",
initialTemplate: "Q{http://www.w3.org/1999/XSL/Transform}initial-template",
});
}
</script>
</head>
<body>
<div id="longformEmptyDiv">
<p>Here is some longformEmptyDiv content.</p>
</div>
<div>Here is some placeholder content.</div>
<div id="shortformEmptyDiv">
<p>Here is some shortformEmptyDiv content.</p>
</div>
</body>
</html>
You will note that the match on longformEmptyDiv correctly inserted the replacement content as a child of the div itself. However, on shortformEmptyDiv the content has replaced everything following the short form div, instead of being inserted into the div. (Consequently, the disappearingAct div goes AWOL. Indeed, its match is never made: no message appears in the browser console: the short form replacement was performed before the disappearingAct template could match.)
