if I have an element with text in it:
<item>What is 1/2 in decimal format?</item>
Is there a way using a style sheet to actually manipulate the text such
that the resulting output would be:
< question>What is <math>1/2</math> in decimal
format</item>
Yes,
Just give us the grammar that generates the sentence.
Then simply follow the steps necessary to work with the LR-Parsing
Framework of FXSL 2.0.
In the FXSL CVS there are examples such as parsing JSON. I have
implemented XPath 2.0 parsing as well.
Here is the signature of the f:lr-parse() function:
23 <xsl:function name="f:lrParse" as="element()*">
24 <xsl:param name="ppTables" as="element()"/>
25 <xsl:param name="pInput" as="xs:string*"/>
26 <xsl:param name="pFunLex" as="element()"/>
27 <xsl:param name="pFunOnRuleReduced" as="element()"/>
28 .......................................
35 </xsl:function>
The meaning of the parameters is the following:
$ppTables -- the YACCX - generated parsing tables (in XML format)
for this grammar. YACCX is a modified Berkeley YACC that produces such
parsing tables.
YACCX can be downloaded from the "tools"
subdirectory of the CVS
$pInput -- the specific instance (of a sentence of the
language) to be parsed.
$pFunLex -- the function (a template reference to it) that performs
the lexical analysis. It takes the string and the current position in
the string. The result is a
sequence of the next position in the string,
the token type just recognized (such as "NUMBER") and the exact value
that matched this token
(such as 223)
$pFunOnRuleReduced -- the function (a template reference to it) that
is called every time a particular grammar rule is reduced. It takes
the rule
(an xml element in the
document provided by $ppTables and the "value stack" ( a sequence of
"values" corresponding to the symbols
comprising this rule),
and produces the value that should be associated with this particular
recognition of the rule.
See for a complete example f:json-document() at:

Well I am 4 days into understanding XSLT (and well 4 days into fully

would be an xml to xml conversion. In my research, I came across XSLT
(along with XSL, XSL-FO, XSD, DTD, etc). My question is the following,
if I have an element with text in it:
<item>What is 1/2 in decimal format?</item>
Is there a way using a style sheet to actually manipulate the text such

Basically, I need to search through the text of an element and attempt
to detect math? Most of the tutorials use xml to HTML as an example and
play with elements and attributes. I was just wandering if the XSLT
spec allows for this type of searching/parsing?
Thanks,
