Re: Remove element that all its descendants have no te

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.

 <xsl:template match="p[span[normalize-space(.)='' and not(*)] and
                        not(span[normalize-space() or *]) and
                        not(*[not(self::span)])]"/>

 <xsl:template match="p[span[normalize-space(.)='' and not(*)] and
                        not(span[normalize-space() or *]) and
                        not(* except span)]"/>

T:\ftemp>type israel.xml
<test>
<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>
</test>
T:\ftemp>xslt israel.xml israel.xsl
<?xml version="1.0" encoding="utf-8"?><test>

<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>
</test>

                     not(span[normalize-space() or *]) and
                     not(*[not(self::span)])]"/>

<xsl:template match="span[not(*) and not(normalize-space(.))]">
</xsl:template>

<xsl:template match="@*|node()"><!--identity for all other nodes-->
  <xsl:copy>
    <xsl:apply-templates select="@*|node()"/>
  </xsl:copy>
</xsl:template>
