hi everyone,

I ecounter a problem for few days.
I don't manage to axpand something like this :

template>>>
<tr id="acteurs" class="acteurs">
<td id="td"><a id="a"/></td>
<td id="descrip"/>
<td id="valeur"/>
<td id="repetition"/>
</tr>
<<<template

ruby code >>>
....
data=Hash.new
data['acteurs']=Array.new
#on fait la liste des acteurs
liste = $_my.query("SELECT * FROM acteur")

i=0
while(result=liste.fetch_hash)
#couleur une ligne sur 2
result['@bgcolor']='#DDDDDD' if(i%2==0)

result['td']=[{"a"=>result['nom'], "@href"=>"toto.php"}]

data['acteurs'].push(result)
i+=1
end

#---------------------
center=template.expand(data)
....
<<<ruby code

The problem is that the href attribute is in the td tag, not in a !
I really looked everywhere in tutorial on xtemplate, and nothing really
helped me.
So, if someone help me out, it would help me very much.

Thanks.

simonced.

The above line should be as follows.

result['td'] = {"a" => {XTemplate::TextNode => result['nom'],
"@href" => "toto.php"}}

Thank you very much !
I didn't understant nothing about it in the documentation.
Is there a good place to get infos about Xtemplate ? The original
website is quite poor about it I think.

Moreover, I have another question.
In the tut, they say I can copy a "part" of one template and past it in
another one. Their exemple works, but not in may app.

main>>>
<html xmlns:xt="#{XTemplate::BIND_URI}">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"
/>
<link href="../styles.css" rel="stylesheet" type="text/css" />
</head>
<body>
<table width="100%" border="0" cellspacing="0" cellpadding="0">

<tr>
<td colspan="2" align="center">
<h3>Gestion de budget - Simulation mensuelle</h3>
</td>
</tr>
<tr>

<td class="navigation" valign="top">
nav
</td>

<td align="left" valign="top">
<div class="centre">
<xt:template name="include">
toto
</xt:template>
</div>
</td>
</tr>
</table>
</body>
</html>
<<<

template>>>
<html xmlns:xt="#{XTemplate::BIND_URI}">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"
/>
<link href="../styles.css" rel="stylesheet" type="text/css" />
</head>
<body>

<xt:template name="include">
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td width="15%"><b>Nom</b></td>
<td width="35%"><b>Description</b></td>
<td width="25%"><b>Montant</b></td>
<td><b>Répétition</b></td>
</tr>

<tr id="acteurs" class="acteurs">
<td id="td"><a id="a"/></td>
<td id="descrip"/>
<td id="valeur"/>
<td id="repetition"/>
</tr>
</table>
</xt:template>
</body>
</html>
<<<

here is the ruby code :
[...]
$_main["include"]=template["include"]
$_main.expand(data)

Sorry, I put all my htm code, but I wasn't sure wich part I could
remove.
Thanks by advance.

Maybe documentations of Amrita are useful for you, since an expansion
argorithm of xtemplate is almost same as one of Amrita.

You must use 'xt:id' instead of 'id', onece you declare the namespace 'xt'.

I'll look better to Amrita documentation.

but, When I runmy script, I have a blank page.
So, to chek errors, I ran my script by a shell.
And I saw this error :
/usr/lib/ruby/site_ruby/1.8/xtemplate.rb:53:in `[]=': undefined method
`children=' for nil:NilClass (NoMethodError)
from index.rb:33
Is it a bug from Xtemplate ?
My code who does it is :
$_main["include"]=template["include"]
How does it work ?

Thanks very much by Advance.

template["include"] returns sub-template named by <xt:template name="...">, and
a sub-template "include" of $_main is replaced with it. Please check both of
$_main["include"] and template["include"].
Also, the following program work on my environment.

Thanks,

require 'xtemplate'
$_main = XTemplate::XMLTemplate.new(<<EOS)
<html xmlns:xt="#{XTemplate::BIND_URI}">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"
/>
<link href="../styles.css" rel="stylesheet" type="text/css" />
</head>
<body>
<table width="100%" border="0" cellspacing="0" cellpadding="0">

<tr>
<td colspan="2" align="center">
<h3>Gestion de budget - Simulation mensuelle</h3>
</td>
</tr>
<tr>

<td class="navigation" valign="top">
nav
</td>

<td align="left" valign="top">
<div class="centre">
<xt:template name="include">
toto
</xt:template>
</div>
</td>
</tr>
</table>
</body>
</html>
EOS

template = XTemplate::XMLTemplate.new(<<EOS)
<html xmlns:xt="#{XTemplate::BIND_URI}">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"

<link href="../styles.css" rel="stylesheet" type="text/css" />

<xt:template name="include">

<td width="15%"><b>Nom</b></td>
<td width="35%"><b>Description</b></td>
<td width="25%"><b>Montant</b></td>
<td><b>Répétition</b></td>
</tr>

<tr xt:id="acteurs" class="acteurs">
<td xt:id="td"><a id="a"/></td>
<td xt:id="descrip"/>
<td xt:id="valeur"/>
<td xt:id="repetition"/>
</tr>
</table>
</xt:template>
</body>
</html>
EOS

data = {'acteurs' => [
{'td' => 'TD', 'descrip'=>'d1', 'valeur'=>'v1', 'repetition'=>'r1'},
]}
$_main["include"]=template["include"]
puts $_main.expand(data)

Yes, thanks, I see it's wroking.
I have to find where I did a mistake.
I have my child script that calls a main script.
The main create $_main var.
Maybe when the script goes back in child script, $_main is not fully
fonctionnal.
I don't know.
I'll investigate for it.
Moreover, my templates are is separate xhtml files, could it change
something ? I don't think so, but I have so weird results...

I'll give news about my investigations about it.
Thanks

Simonced.

I discovered a strange problem !
Did anybody sever swa that ?!
When I load my Template with a string from within the code, it's
working !
ex :
template=Xtemplate::XMLTemplate.new(<<EOS)
[...content of the XHTML template here...]
EOS

But, if my template is in a separated file it's not working, I load it
like this :
template = Xtemplate::XMLTemplate.new(IO.read("../acteurs/acteurs.htm")

Does somene know where there is a problem ?
Thank by advance

Simonced.

Does anyone knoes why
template =
Xtemplate::XMLTemplate.new(IO.read("../acteurs/acteurs.htm")
doesn't work at all ?
IO.read has special properties ?

Thx for help
