Subject: RE: [xsl] How to use the same expression in a match and a select test From: "Michael Kay" <mike@xxxxxxxxxxxx> Date: Mon, 3 Dec 2007 13:57:17 -0000 |
You're using XSLT 2.0 so you can write $NO_BLOCK_ELEMENTS and $SAME_ATTRIBUTES as stylesheet functions returning a boolean: <xsl:function name="f:is-no-block-element" as="xs:boolean"> <xsl:param name="n" as="element()"/> <xsl:sequence select="not(self::blockquote|self::center...)"/> </xsl:function> match="*[is-no-block-element(.)]" Alternatively, many of the elements listed have a schema type of Inline in the XHTML schema, so you could refer to them collectively as element(*, Inline) if you import the schema. The test string-join(@*,'xx') = string-join(current()/@*,'xx') looks wrong - it's relying on the order in which attributes are returned by @*, which may vary from one element to the next. It looks to me as if your code could also benefit from using <xsl:for-each-group group-adjacent="..."> Michael Kay http://www.saxonica.com/ > -----Original Message----- > From: Sascha Mantscheff [mailto:922492@xxxxxx] > Sent: 03 December 2007 13:21 > To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx > Subject: [xsl] How to use the same expression in a match and > a select test > > I have a stylesheet with a template and a for-each statement. > Both select their elements by an expression which differs > only in one part from each other. > > The template is: > > <xsl:template match="*[not(self::blockquote|self::center|self::BODY| > self::body|self::div|self::dl|self::dt|self::HEAD|self::head|s > elf::HTML| > self::img|self::h1|self::h2|self::h3|self::h4|self::h5|self::h6| > self::hr|self::html|self::idx:*|self::form| > self::mbp:*[not(self::mbp:nu)]|self::mmc:*|self::ol|self::p|se > lf::table| > self::td|self::th|self::tr| > self::ul)][preceding-sibling::node()[1][name()=name(current()) and > string-join(@*,'xx') = string-join(current()/@*,'xx')]]" > /> > > The for-each select is: > > <xsl:for-each > select="following-sibling::node()[1][not(self::blockquote| > self::center|self::BODY|self::body|self::div|self::dl|self::dt| > self::HEAD|self::head|self::HTML|self::img|self::h1|self::h2|self::h3| > self::h4|self::h5|self::h6|self::hr|self::html|self::idx:*|self::form| > self::mbp:*[not(self::mbp:nu)]|self::mmc:*|self::ol|self::p|se > lf::table| > self::td|self::th|self::tr|self::ul)] [name()=name(current()) and > string-join(@*,'xx') = string-join(current()/@*,'xx')]"> > > How can I reduce the redundancy and use the same expression > in both statements, like in this pseudo code: > > <xsl:template > match="*[$NO_BLOCK_ELEMENTS][preceding-sibling::node()[1][name > ()=name(current()) and $SAME_ATTRIBUTES]]" > /> > > <xsl:for-each select="following-sibling::node()[1][$NO_BLOCK_ELEMENTS] > [name()=name(current()) and $SAME_ATTRIBUTES]">
