& transforms to & which is a problem in xml

[tobiaszuercher]

bug description

because the environment file is xml, we need to html encode characters like for example "&". example:

<variable name="url" value="www.google.ch?q=tobi&amp;anotherParameter=1337" />

but if this variable gets used in an template which is a xml file:

<add key="url" value="${url}" />

it will html decode the value:

<add key="url" value="www.google.ch?q=tobi&anotherParameter=1337" />

which is invalid xml.

current workaround:

In environment file: &xxx; -> &xxx;xxx;

<variable name="url" value="www.google.ch?q=tobi&amp;amp;anotherParameter=1337" />

idea how to fix

in a template, give the user the ability to apply a filter for the value ${url | htmlencode}
