OK. I've approached this problem with limited Javascript and XML
experience so I'm hitting a wall fairly early on. I'll describe my
problem, and if anyone can help it'd be great. I know this may not be
the most appropriate forum for my question, though, so I apologize in
advance for asking.
This is the kind of string I get from my calendar, for the venue:
SAT (Societé des arts technologiques), 1195 St-Laurent
Note that the venue may have accented characters in it.
This is the entry in my XML file for this particular venue:
<marker label="SAT (La Soci&eacute;t&eacute; des arts
technologiques)" html="<img style="float:left;padding:
2px;border:1px double #999;margin-right:12px;" width="
90" height="67" src="http://base.googlehosted.com/
base_media?q=LBC-4808530-1525157559&size=2&hl=en" /
><strong><a href="http://www.sat.qc.ca">SAT
(La Soci&eacute;t&eacute; des arts technologiques)</
a></strong><br />1195 boul St-Laurent<br />(514)
844-2033" lat="45.509445" lng="-73.562714" />
Note that in the XML file, all the accented characters, plus the < and
> and & and " must be encoded.
What I need to do:
1. Obtain the venue name from the event page. (I'll call it
$venuename.) This is trivial either in PHP (because it's already used
in creating the page ) or Javascript (via getElementById)
2. Open my XML file
3. Encode $venuename with the appropriate entities (because it comes
from the calendar unencoded and thus won't match the XML file)
4. Search within the XML file to find a match between $venuename and
the element marker's attribute named "label".
5. - If match is found, return the entire element with that marker to
the script, then create the map with it.
5. - If no match is found, return nothing and don't create a map
6. Close XML file
I've been reading about various XML parsers and about Javascript text
processing and I'm at a loss about which to use. For the past 5+ years
I've mostly worked with other people's scripts, and haven't written
anything from the ground-up for a long time. This is where I'm at
right now:
- In my entry page (PHP script), I can either insert the Javascript
into the resulting page, doing all the opening/reading/comparing
$venuename/returning the entire XML element/outputting the map in
Javascript. OR I can open and read and compare and return the XML
element in PHP, and insert the result into a bit of Javascript that
just creates the map.
- I'm a bit lost, I guess, because I've never really worked with XML
before. I know there are parsers and such but I'm unfamiliar with how
they work.
- I think the problem is less about not knowing Javascript (I could
probably just look for equivalent functions to languages I already
know) but about not knowing how XML is processed.
- I'm sure if I think this out long enough I'll figure something out,
but I don't know much about best-practices wrt Javascript *or* XML
- I seem to only work on this project when I'm lacking sleep.
- My skills really needed to be brought out of the dark ages and
introduced to OOP and frameworks and browser-based stuff anyway, so it
will be good for me to learn this stuff somehow.
- I know this is my own fault for getting in over my head so I
apologize again for inappropriate or stupid questions!
