[GRASS-dev] SQL inequality and GXW files

GRASS GRASS developer

I'm using 6.4.0RC3 on OSX 10.4.11 (Kyngesburye release) using the WxPython GUI. I set up a where clause for a vector display (ATTR<>'ABC'), which works fine. I then save the workspace as "test.gxw". No problem there.

When I try to open the test.gxw workspace file I get the error message:

Error
Reading workspace file <..../test.gxw>
failed. Invalid file, unable to parse XML document.
<unknown>:17:35: not well-formed (invalid token)

I open up the file using emacs and it immediately flags the "<" in the "<>" field:

<parameter name="where">
     <value>ATTR<>'ABC'</value>
</parameter>

since it believes the "<" is opening a markup tag.

I edit the file to change "<>" to &lt;&gt; and try to open the workspace file again. This time the workspace gets loaded just fine. Tried to save with the SQL "cat<10". File saves OK but I get the same error when trying to open that gxw file. I change the "<10" to "&lt;10" and the file opens and the vector displays no problem.

I guess the GXW save facility needs to check for the "<" symbol and replace it with "&lt;"

Thanks,

Joe

The “ampersand-lt-semicolon” got changed to “<” at the nabble site. Just to make sure the post makes sense I’ve changed the previous post. See below… Joe

Subject: SQL inequality and GXW files

I’m using 6.4.0RC3 on OSX 10.4.11 (Kyngesburye release) using the WxPython GUI. I set up a where clause for a vector display (ATTR<>‘ABC’), which works fine. I then save the workspace as “test.gxw”. No problem there.

When I try to open the test.gxw workspace file I get the error message:

Error
Reading workspace file <…/test.gxw>
failed. Invalid file, unable to parse XML document.
:17:35: not well-formed (invalid token)

I open up the file using emacs and it immediately flags the “<” in the “<>” field:

ATTR<>'ABC'

since it believes the “<” is opening a markup tag.

I edit the file to change “<>” to “ampersand-lt-semicolon ampersand-gt-semicolon” and try to open the workspace file again. This time the workspace gets loaded just fine. Tried to save with the SQL “cat<10”. File saves OK but I get the same error when trying to open that gxw file. I change the “<10” to “ampersand-lt-semicolon 10” and the file opens and the vector displays no problem.

I guess the GXW save facility needs to check for the “<” symbol and replace it with “ampersand-lt-semicolon”

Hi,

2009/3/16 Joe Ostrowski <jtostrowski@comcast.net>:

I'm using 6.4.0RC3 on OSX 10.4.11 (Kyngesburye release) using the WxPython
GUI. I set up a where clause for a vector display (ATTR<>'ABC'), which
works fine. I then save the workspace as "test.gxw". No problem there.

When I try to open the test.gxw workspace file I get the error message:

Error
Reading workspace file <..../test.gxw>
failed. Invalid file, unable to parse XML document.

this bug has been already fixed - wait for RC4 or use relbr64 directly.
