Try https rather than http.  We're under a directive from the Office

Re: [Qgis-user] xml metadata in PostGIS table

[Schweitzer, Peter]

Richard,

In PostgreSQL, I store some whole documents as XML, using

create table something (
  rec_id integer,
  record xml
  );

and then insert like this:

insert into something (rec_id,record) values ( 1,XMLPARSE (DOCUMENT
'<...'));
By defining the field "record" as xml, I can use XML functions within
PostgreSQL to look at the contents (though I rarely do this).  But the
parsing step also catches improper XML and rejects the insert with an
error message, very helpful.

Is this the sort of information you're after?

Peter

Re: [Qgis-user] QML reference, symbolize synonyms alike

[Schweitzer, Peter]

With many thanks to Richard McDonnell, his suggestion of using rules
instead of categories solved the problem I had.  The result is
http://mrdata.usgs.gov/geology/state/lithclass.qml with context
provided by http://mrdata.usgs.gov/geology/state/

I'm still a little puzzled by what's required and what is not required
in the QML file; I'm guessing that the solution would be to delve into
the QGIS source code, but it would be nice to have at least a
rudimentary document; I simply used the automatically-generated qml as
an example, then omitted a lot of things, but was pleased at how
simple I could make it and have it still work.

Thanks!

Peter

[Qgis-user] QML reference, symbolize synonyms alike

[Schweitzer, Peter]

Is there a QML reference document?

What I really want to do is specify that two different category values
will have the same symbol, like this:


I want to read this as

when the value of the attribute is EITHER "carbonate rock" OR
"carbonate", render the feature using the symbol named "64"

But this does not have the effect that I want, so I'm thinking
incorrectly about how the QML file works.

I would welcome advice on how to do what I want, or direction to the
QML reference, or both.

Thanks!

Peter
