Escape Characters for RAQL Queries
You can enter RAQL queries as either the value of the the <raql> element in a mashup or as the value of the query attribute in <raql>. Because the query is in an XML file (the mashup), you must use the escaped form of the following XML delimiters when they appear in a RAQL query:
& use
&< use
< > use
> In addition, you may have to escape either the single or double quote mark when they appear in the query if that quote mark is used as the delimiters for the query attribute. The escaped forms are:
" use
" ' use
' For example:
<raql query="select name,descr,"date" from myVar" outputvariable="result"/>
Or:
<raql query='select name,descr from myVar where descr like 'Arnold%'' outputvariable="result"/>
