Re: Building select-clause dynamically with parameters

Probably you think that the following applies the appropriate templates
to ***all*** of the set of the a "chapter" node and its descendents,
the string value of which contains the value of $query?

    <xsl:template match="/">
      <xsl:apply-templates 
select="chapter[contains(descendant-or-self::*,$query)]"/>
    </xsl:template>


This is wrong. The above code will apply a template only to every
"chapter" node, the text of which contains that of $query -- not to any
descendent of a "chapter", even if the descendent contains the text of
$query.

At first it may seem that a "chapter" will be selected if one of its
descendents contains $query -- this may not be the case. A "chapter"
may be selected even if none of its descendents (including its own
children text nodes) contains $query. This will be the case, when
$query is "made up" by the concatenation of the text of several
descendents.

It seems to me that the code above does not express at all what you
wanted.

Hi,

I would like to pass some words into my XSL file which should be used
to build an XPath query in xsl:apply-templates. For an example, the

following

works, but only for one word:

    <?xml version="1.0" encoding="ISO-8859-1"?>
    <xsl:stylesheet version="1.0"
     xmlns:xsl="http://www.w3.org/1999/XSL/Transform";  

    <xsl:param name="query"/>

    <xsl:template match="/">
      <xsl:apply-templates 
select="chapter[contains(descendant-or-self::*,$query)]"/>
    </xsl:template>

    <xsl:template match="chapter | section">
      <table>
        <tr>
          <td>&#160;</td>
          <td>Found <xsl:value-of select="title"/>
            <xsl:apply-templates 
select="section[contains(descendant-or-self::*, $query)]"/>
          </td>
        </tr>
      </table>
    </xsl:template>

    </xsl:stylesheet>

I don't know how many words will be passed into the XSL file, this

should

be flexible.
For example, If $query has the value "word1 word2", the only chapters

and

sections that
should be selected by apply-templates are those which contain word1

or

word2, I think
in this case need I something like:

      <xsl:apply-templates 
select="chapter[contains(descendant-or-self::*,'word1') or

contains(descendant-or-self::*,'word2')]"/>


I tried to pass the whole string used by "select" as parameter, but

it does

not work.

Another thing is that I also have words that should be excluded and

that I

would like
to pass a value into the XSL file that should define if it is an AND

or an

OR query to
build something like:

      <xsl:apply-templates 
select="chapter[contains(descendant-or-self::*,'word1') and

contains(descendant-or-self::*,'word2')

and

not(contains(descendant-or-self::*,'word3'))]"/>


Has anyone an idea how to do something like this? Or is it a better 
solution to do this
with Java DOM?

Thanks for help and greetings,

Marko
