[Zope] RE: html2pdf truncating html content

Mon Jul 17 12:21:42 EDT 2006

Found the problem:  context was changing.  When called from html2pdf,
the parent object was different from when the dtml was called raw.

some more wags:

1) remove the html comments from the generated html code (ie. get rid of
the <!-- PAGE BREAK --> tags)
2) remove the body loop and hard code in a 1 liner instead eg. body
+='some new text' and see what happens
3) where are the <html> and </html> tags added into the html code you
pass to html2pdf? (they weren't in the python code you posted)

	Thanks, Jonathan, but no joy.  Testing for the value of of
d.title before writing it doesn't change the output and even a hardcoded
body+="text goes here" just inside the for loop doesn't get printed.

	Just a wag (wild assed guess)... in your BODY loop, if d.title
is null could you be embedding a 'null' char in the text string, which
may cause html2pdf to choke?

		Refinement of problem statement:

		The DTML file on which html2pdf is called is populated
by a python script which builds and returns html by processing a list of
objects in a for loop.  The html content which is missing from the pdf
is generated inside the for loop.  As said before though, the
information built in the for loop is displayed in the DTML when it is
viewed as a webpage.

		The python is below:

		data = [n for n in context.objectValues(['RDMA
Narrative','RDMA Indicator']) if n.country==selectedCountry] 

		body=""

		##TITLE PAGE
		body+="<h1>%s</h1>\n" % selectedCountry
		body+="<!-- PAGE BREAK -->\n"

		##BODY
		for d in data:
		  body+="%s\n" % (d.title)
		  if d.meta_type == 'RDMA Indicator':
		    if hasattr(d,'xltohtml'):
		      body+=d.xltohtml()
		  elif d.meta_type == 'RDMA Narrative':
		    body+="<h3>%s</h3>" % d.narrativeType
		    body+=d.narrativeText
		  body+="<!-- PAGE BREAK -->\n"

		return body

		Subject: [Zope] RE: html2pdf truncating html content

		I'm using html2pdf and it seems to be truncating the
content.  The html on which html2pdf is:

		<html>
		<head><title>Narrative Report</title></head>
		<body>

		<h1>PNG</h1>
		<!-- PAGE BREAK -->
		<h2>Narrative: PNG- Challenge Situation</h2>
		<!-- PAGE BREAK -->
		<h2>Narrative: PNG- Key Accomplishments</h2>
		<!-- PAGE BREAK -->
		<h2>Narrative: PNG- Program Performance</h2>

		<!-- PAGE BREAK -->
		<h2>Narrative: PNG- Success Stories</h2>
		<!-- PAGE BREAK -->
		<h2>Table 1-2 PNG</h2>
		<!-- PAGE BREAK -->
		<h2>Table 1-4 PNG</h2>
		<!-- PAGE BREAK -->
		<h2>Narrative: PNG- Annex II</h2>
		<!-- PAGE BREAK -->
		<h2>Narrative: PNG- Annex III</h2>
		<!-- PAGE BREAK -->

		</body>
		</html>

		The html which html2pdf is writing to the pdf though is:
		<html>
		<head><title>Narrative Report</title></head>
		<body>

		<h1>PNG</h1>
		<!-- PAGE BREAK -->

		</body>
		</html>

		I'm at a loss to explain the truncation.  Can anyone
offer some suggestions?
