Hi,
How to embed ruby code in xml .
here is my XML template :
string = <<EOF
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE ozxmlscene>
<ozml version="4.0">
<styleRun style="1091379" offset="0"
length="7"/>
<text>The End</text>
<object value="84"/>
<object value="104"/>
<object value="101"/>
<object value="32"/>
<object value="69"/>
<object value="110"/>
<object value="100"/>
<override>0</override>
<aspectRatio>0.8999999762000001</aspectRatio>
</ozml>
EOF
xml = string.gsub(''"'',"''")
I need to use loop below <text> tag generating object values dynamically
.
How to embed this in xml ?
end_title_name.each_byte do |title|
"<object value=title/>"
end
thanks,
sri..

hi, My file contains 5000 lines in which only 1000 lines are custom . So if use builder i should write by hand all these lines . thanks sri..

The ERb could render the XML without needing Builder. But your approach is very interesting, and I''ll keep it in mind. I do have a question, though: what''s the advantage of embedding Builder in ERb as you did, rather than having the ERb file call a Builder partial?> > Cheers, > WalterBest, -- Marnen Laibow-Koser http://www.marnen.org marnen-sbuyVjPbboAdnm+yROfE0A@public.gmane.org -- Posted via http://www.ruby-forum.com/.
But i was looking to generate XML behind the scenes and it will write to a new file every time . If we use .erb this will try to render on screen ? right thanks sri.

Nokogiri''s builder is significantly faster than Builder from our testing at the time. Although you can swap parsing libs now in Rails, you still can''t use ".xml.nokogiri" yet. We used ERB in order to use Nokogiri, since the output is returned to ERB as a string. Cheers, Walter

Can we generate dynamic xml using REXML/XML Builder ? My requirement is to use a sample xml template which contains 5000 lines and each time when user clicks on GO, we will create a new xml file generating all 5000 lines and only approx 3000 lines will be dynamic like Eg: photo name , photo title, time, etc. So in my public folder i will have N no. of xml files for N no. of users (all files will generate 5000 lines) thanks sri..
