Extraneous spaces in XML documents
I'm typesetting some XML text with comments in and for the working version the comments are to go in the margin. For the final version the comments are simply to be ignored. In the end result there is a noticeably larger space between the words where the comma had been. Apparently more than one space is reaching TeX's stomach, though it's beyond me to work out how.

you can use \gobbleoneargument here the next solution may help: \defineXMLargument [comment] \XMLhideelement \long\def\XMLhideelement#1% {\futurelet\nexttoken\doXMLhideelement} \def\doXMLhideelement {\ifx\nexttoken\blankspace\removeunwantedspaces\fi} maybe i will add something \defineXMLhide; will think about it Hans ------------------------------------------------------------------------- Hans Hagen | PRAGMA ADE | pragma@wxs.nl Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: +31 (0)38 477 53 69 | fax: +31 (0)38 477 53 74 | www.pragma-ade.com ------------------------------------------------------------------------- information: http://www.pragma-ade.com/roadmap.pdf documentation: http://www.pragma-ade.com/showcase.pdf -------------------------------------------------------------------------

Actually, \gobbleoneargument doesn't make any difference, but the \XMLhideelement solution works perfectly. thanks robbie
the next solution may help:
\defineXMLargument [comment] \XMLhideelement
\long\def\XMLhideelement#1% {\futurelet\nexttoken\doXMLhideelement}
\def\doXMLhideelement {\ifx\nexttoken\blankspace\removeunwantedspaces\fi}

You should use \ignorespaces in the end tag. Unfortunately, \defineXMLargument does not allow you to define the action for the end tag. This would work: \defineXMLenvironmentsave [comment] {} {\ignorespaces} The save action gobbles the content as well. Regards, Simon -- Simon Pepping email: spepping@scaprea.hobby.nl

Thanks. Is this conceptually different to writing \def\gobble#1{\ignorespaces} \defineXMLargument [comment] \gobble ? It seems to have the effect of also devouring the necessary space after a full stop, if the comment tag comes directly after it in the source: Makes complicated pages by starting.<comment>This is not a proper sentence.</comment> With simple ... The space after the comment, before "With" should get into the final document, but doesn't make it. (on the other hand, this also happens when the comments are shown with \defineXMLargument [comment] \inmargin cheers, robbie

kind of, in tex mode, it gobble spaces and takes the next argument or token Hans ------------------------------------------------------------------------- Hans Hagen | PRAGMA ADE | pragma@wxs.nl Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: +31 (0)38 477 53 69 | fax: +31 (0)38 477 53 74 | www.pragma-ade.com ------------------------------------------------------------------------- information: http://www.pragma-ade.com/roadmap.pdf documentation: http://www.pragma-ade.com/showcase.pdf -------------------------------------------------------------------------

No, that seems to be the same thing, and a good way to do it. I missed that.

Yea, that is the problem. If you remove the spaces, you do it everywhere. I think it would be a better solution if you write your document carefully, and not gobble the spaces: Makes complicated pages by starting. <comment>This is not a proper sentence. </comment>With simple ...
