Encoding

All variables in RXML 2 are accessed through entities, e.g. &var.foo;.

By default, an entity will be HTML encoded, that is, < will be inserted as &lt;, > as &gt; and & as &amp;. However, there are instances when that is not what you want, for example, when inserting entities into SQL queries. Therefore, the encoding can be controlled by applying another encoding scheme on the entity, &scope.entity:scheme;.

<sqlquery query="SELECT * FROM db WHERE name='&form.name:mysql;'">

Available Encoding Schemes

• none
  

  No quoting. This is dangerous and should never be used unless you have total control over the contents of the variable.

• html
  

  The default quoting, for inserting into regular HTML or RXML. Encoded characters are &, <, >, ", ' and the null character.

• url
  

  For inserting variables into URLs. Encoded characters are the null character, space, tab, the newline character, the carriage return character, %, ', ", #, &, ?, =, / and :.

• http
  

  Uses a subset of the URL encoding scheme. Characters & and ? are not encoded as it would make inserting i.e. variables into http-strings impossible. Encoded characters are the null character, space, tab, the newline character, the carriage return character, %, ' and ".

• cookie
  

  Uses a subset of the URL encoding scheme. Only the characters =, ,, ; and % are encoded.

• pike
  

  For inserting into Pike strings, for use with the <pike> tag. Encoded characters are ", \ and the newline character.

  For inserting into Javascript strings. Encoded characters are the backspace character, the formfeed character, the newline character, the return carriage character, tab, \, ' and ".
