Subject: Re: [xsl] formatting text with nested features From: "M. David Peterson" <m.david@xxxxxxxxxx> Date: Fri, 24 Oct 2003 05:20:57 -0600 |
Dont have an FO parser on this machine but in standard HTML format the
following has been tested in IE using msxml4 ( i believe thats whats on here
but it may just as well be msxml3.)
XML...
<?xml version="1.0" encoding="utf-8" ?>
<?xml-stylesheet type="text/xsl" href="test.xslt" ?>
<main>
<body>
<p>
normal normal <b>bold bold <i>bold-italic</i> bold bold<sub>3</sub>
</b> normal<sup>5</sup> normal
</p>
</body>
</main>
Parsed with the following XSLT...
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [
<!ENTITY nbsp " ">
]>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:template match="/">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="p">
<p>
<xsl:apply-templates/>
</p>
</xsl:template>
<xsl:template match="b">
<b>
<xsl:apply-templates/>
</b>
</xsl:template>
<xsl:template match="i">
<i>
<xsl:apply-templates/>
</i>
</xsl:template>
<xsl:template match="sub">
<sub>
<xsl:apply-templates/>
</sub>
</xsl:template>
<xsl:template match="sup">
<sup>
<xsl:apply-templates/>
</sup>
</xsl:template>
</xsl:stylesheet>
produces the following result (not sure if it will make it through the list
processor correctly but I assure you it gives you the result you want. Just
replace my HTML with the correct FO elements and youll be all set.
normal normal bold bold bold-italic bold bold3 normal5 normal
If you want to have special cases for specific nested elements such as
<b><i>foo</i><sub>2</sub></b> then just add additional templates that
specify the pattern in the match attribute of the template.
So the XML...
<main>
<body>
<p>
normal normal <b>bold bold <i>bold-italic</i> bold bold<sub>3</sub>
</b> normal<sup>5</sup> normal
</p>
<p>
normal normal <b>bold bold</b> <b><i>bold-italic</i></b> <b>bold
bold<sub>3</sub></b> normal<sup>5</sup> normal
</p>
</body>
</main>
Processed with this XSLT...
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [
<!ENTITY nbsp " ">
]>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0" xmlns:msxsl="urn:schemas-microsoft-com:xslt"
xmlns:my="urn:my-scripts">
<xsl:template match="/">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="p">
<p>
<xsl:apply-templates/>
</p>
</xsl:template>
<!-- special case template for <b> elements that contain <i> elements but
not if they contain a <sub> element as well -->
<xsl:template match="b[i][not(sub)]">
<h1>
<xsl:apply-templates/>
</h1>
</xsl:template>
<xsl:template match="b">
<b>
<xsl:apply-templates/>
</b>
</xsl:template>
<xsl:template match="i">
<i>
<xsl:apply-templates/>
</i>
</xsl:template>
<xsl:template match="sub">
<sub>
<xsl:apply-templates/>
</sub>
</xsl:template>
<xsl:template match="sup">
<sup>
<xsl:apply-templates/>
</sup>
</xsl:template>
</xsl:stylesheet>
Will produce the following result...
normal normal bold bold bold-italic bold bold3 normal5 normal
normal normal bold bold
bold-italic
bold bold3 normal5 normal
Again, may not make it through the list processor in the proper format. To
test it just save the XML as a test.xml file and the XSLT as test.xslt in
the same directory and open the xml file in IE.
Hope this helps!
Best regards,
M.
