XSLT: concat and quotes

[Gerald Aichholzer]

Hello,

I need to specify the following attribute in an xhtml-file
containing TAL templates:

<div tal:attributes="onMouseOver concat('func(',xyz,')')">

which results in

<div onMouseOver=func( )>
^
value of xyz here


My problem is, that I need to put quotes around the content
of xyz:

<div onMouseOver=func(' ')>


How can I achieve this? The double quotes are already in
use by tal:attributes, the single quotes are used by the
concat-function.

thanx in advance,
Gerald

I don't know what TAL is but if you are asking about the XPath function
concat then you need to split up the string into parts containing single
quotes and into parts contaning double quotes if needed e.g.
<xsl:value-of select="concat('func(', &quot;'&quot;, 'xyz',
&quot;'&quot;, ')'" />

I'm speaking about the XPath function concat. I think I should
have specified my problem a little bit better. In my application
the tal:attributes works as follows:

<div tal:attributes="attrname XPath-expression">

where

attrname is the name of an attribute which is created
XPath-expression specifies an XPath-expression which
value is assigned to the attribute.

e.g.

<div tal:attributes="sample concat('hello',' ','world')">

will be expanded to

<div sample="hello world">


My problem is, that I need single _and_ double quotes in
the strings used by concat, but the double quotes are
already used for tal:attributes="..."

I don't think that

<div tal:attributes=
"sample concat('hello ','"',$world,'"')">

will work, because the second " is considered to be the
end of tal:attributes.

If $world="gerald" then the above should result to

<div sample="hello 'gerald'">

How can I achieve this?

Thanx in advance,
Gerald

You need to escape the double quotes then

<div tal:attributes=
"sample concat('hello ','&quot;',$world,'&quot;')">

<div tal:attributes=
"sample concat('hello ','&quot;',$world,'&quot;')">

Thank you very much
