export: graphic url (special chars?)

export: graphic url (special chars?)

[Reviczky, Adam]

Hi

The following example results in a broken xml as well:
--
\setupbackend[export=test.xml]
\starttext
\externalfigure[https://chart.googleapis.com/chart?cht=p3&chs=250x100&chd=t:60,40&chl=Hello\letterbar World][method=png,scale=4000]
\stoptext
---

XML Parsing Error: not well-formed
Location: file:///home/reviczky/Downloads/test/test.xml
Line Number 10, Column 74:

The problem is with the name property:
name='https://chart.googleapis.com/chart?cht=p3&chs=250x100&chd=t:60,40&chl=Hello|World'

Further, if the url has a "%" symbol then the name property stops at that, see:
---
\setupbackend[export=test.xml]
\enabledirectives[schemes.cleanmethod=md5]
\def\googlechart
 {\begingroup
  \setcatcodetable\vrbcatcodes
  \dodoubleempty\dogooglechart}
\def\dogooglechart[#1][#2]%
  {\endgroup
   \externalfigure[#1][method=png,#2]}
\starttext
\googlechart[http://chart.apis.google.com/chart?chs=350x220&cht=p3&chd=s:G99p&chdl=2|1|1|6|2|0|52|52|2|2|1|1|2|2|2|2|2|1|1|2|2|1|1|1|2|1|1&chdlp=b&chp=0.1&chl=fsharp|gettext|gettext-base|Others%20%2824%29&chma=95,95&chtt=Launchpad+Statistics+for+%7Ereviczky+-+ppa&chts=676767,13.5][factor=max]
\stoptext
---

gives:
name='http://chart.apis.google.com/chart?chs=350x220&cht=p3&chd=s:G99p&chdl=2|1|1|6|2|0|52|52|2|2|1|1|2|2|2|2|2|1|1|2|2|1|1|1|2|1|1&chdlp=b&chp=0.1&chl=fsharp|gettext|gettext-base|Others'

Though I guess this is not really a problem.

You could try (untested)

\def\googlechart[#1][#2]%
   {\externalfigure[#1][...]%
    \endgroup}

or

\def\dogooglechart[#1][#2]%
   {\useexternalfigure[googlechart][#1]%
    \endgroup
    \externalfigure[googlechart][...]}

Thanks, but it has the same result.

That screws up the url in the css (gives a url(googlechart) in the css).

Btw. this is not really about google charts, I just took that as an example.
