I want to remove span elements that have empty text nodes and no
further descendants.
In case the p has ONLY empty spans I want to remove it alltogether.
Example:
<p dir="rtl"><span id="textStyle10"></span></p>
<p dir="rtl"><span id="textStyle10">Some text.</span> <span
id="textStyle10"></span></p>
<p dir="rtl"><span id="textStyle10"></span><sup>1</sup></p>
<p dir="rtl"><span id="textStyle10"><br /><br /></span></p>
Desired output:
<p dir="rtl"><span id="textStyle10">Some text.</span> </p>
<p dir="rtl"><sup>1</sup></p>
<p dir="rtl"><span id="textStyle10"><br /><br /></span></p>
In case it is too complicated I can live with such output (remove p
that all its spans have empty text nodes):
<p dir="rtl"><span id="textStyle10">Some text.</span> <span
id="textStyle10"></span></p>
<p dir="rtl"><span id="textStyle10"></span><sup>1</sup></p>
<p dir="rtl"><span id="textStyle10"><br /><br /></span></p>
I tried the following:
<xsl:template match="p[span[normalize-space(.)='']]"/>
but it removes the p even if only one span is empty.
Did you try:
<xsl:template match="p[span[normalize-space(.)='' and not(*)] and
not(span[normalize-space() or *]) and
not(*[not(self::span)])]"/>
... which will remove the paragraph if there is at least one empty
span, no non-empty spans, and nothing other than a span element child.
A working illustration for XSLT 1 is below. For XSLT 2 you can use:
<xsl:template match="p[span[normalize-space(.)='' and not(*)] and
not(span[normalize-space() or *]) and
not(* except span)]"/>
I hope this helps.
