If the context node is a <br/> element, then
test="preceding-sibling::node()[1][self::br]"
tests whether the immediately preceding node is also a <br/> element.

Subject: [xsl] detecting text between nodes
dear xsl-specialists,
i try write an xsl to transform html-documents (with a restricted
html-subset) directly to fo.
my only problem is the <br/>-tag:
if i have "aaa<br/>bbb<br/>ccc"
then i simply have to replace each br-tag with a <fo:block/>
just to insert
a line-break.
but if i have "aaa<br/><br/>bbb" the first br is responsible for the
line-break and the second will insert an empty line, i.e. i
have to convert
the second br-tag to something that inserts an empty line:
"aaa<fo:block/><fo:block space-after="10"/>bbb"
so, the attribute "space-after=10" is present if the
preceding sibling is a
"br" and there is nothing except whitespace between the
current br and the
preceding br;
but how can i express this condition with xpath?
<xsl:template match="br">
<fo:block>
<xsl:if test="name(./preceding-sibling::*[1])='br' and
NOTHINGBUTWHITESPACEBETWEEN(.,./preceding-sibling::*[1])">
<xsl:attribute name="space-after">10pt</xsl:attribute>
</xsl:if>
</fo:block>
</xsl:template>
tia for any hint!
fusel!
