Hi All,
I am beginner with QlikView and I had to face a challenge of extracting the plain text by parsing RTF/RichText. Seems to be an easy problem and the solution is even easier ,but it took me some time to arrive at the solution, hence i would like to share it with the community.
I created a custom function in QlikView by writing a JScript in the Edit Module (CTRL +M) space. The function is as shown below
function convertToPlain(rtf)
{
rtf = rtf.replace(/\\par?/g, "");
return rtf.replace(/\{\\[^{}]+;\}|[{}]|\\\n?[A-Za-z]+\n?(?:-?\d+)?[ ]?|[{\\\*}]/g, "");
}
All this function does is replaces the string which matches the regex expression marked in bold with a empty string "" . I am sure that some of you can write a better Regex Expression, but this was the one which worked for me(there are lot of posts where you find different regex expression which might work for you but you need to do thorough testing). You can use websites such as https://regex101.com/ to build your own Regex Exp and test it.
Now all you have to do is to call this function in your load script as shown below
Load convertToPlain(<YourRTFColumn>) from <YourSource>;
Please feel free to contribute if you think there is a better way to do it or someone wants to add on to this.
