Import of Word Documents to ServiceNow Knowledge base

welterp · ‎02-10-2014

I am trying to import Word Documents to ServiceNow Knowledge Articles with out losing any images. I have tried using the Word Cleaner and SED installs without any success. Is there any fix that works?

IMPORTANT UPDATE - 03/03/2016:

I updated the entire script as I ran into some errors. And now it can also be used with journal fields!

See my reply: Re: Import of Word Documents to ServiceNow Knowledge base

You can also read more about it here: Create Knowledge Base Article (HTML field) or Comments (Journal field) from Email

you corrected the thrown exception errors on 4 of the lines in the script.

example on your line 18 with the part:

while(match == regex.exec(searchBody)){

the actual script is

while(match = regex.exec(searchBody)){

I know it throws an errors, but that's somehow required for the script to work. Because later you're going to use the value in the variable 'match' that has been set in line 18... If somebody has any idea how to formulate this correctly, you're welcome to help out.

Here is the full script that I use:

var gdt = new GlideDate();

gdt.addDays(2);

//current.valid_to = gdt;

var desc = email.subject;

desc = desc.replace("Knowledge:","");

current.short_description = desc.trim();

current.workflow_state = "draft";

current.topic = "General";

//current.category = "";

current.roles = "knowledge";



//Find and replace the image tags with the proper source.

//Get the number of attachments so the loop can be exited

//so it will stop no mater what.

var currentCount = 0;

var newBody = email.body_html;

var searchBody = email.body_html.replace(/\n/g, " ");



var regex = /<img(.*?)>/ig;

var match;

var match2;

while(match = regex.exec(searchBody)){

   //Add a style float tag next to the align tag.

   var alignText = match[0].replace(/align=['"]?left['"]?/gi, 'align="left" style="FLOAT: left"');

   alignText = alignText.replace(/align=['"]?right['"]?/gi, 'align="right" style="FLOAT: right"');

   searchBody = searchBody.replace(match[0], alignText);

   var regex2 = /src=("(.)*?"|'(.)*?'|(.)*?\s+$)?/ig;

   while(match2 = regex2.exec(alignText)){

   findAndReplaceImage(match2[1].replace(/\s+$/,"").replace(/"+/g,"").replace(/'+/g,""));

   }

   currentCount += 1;

   if(currentCount >= 100)

   break;

}

searchBody = searchBody.replace(/<o:p>(.*?)<\/o:p>/ig, "");

currentCount = 0;

var regex2 = /<!--\[if(.*?)<!\[endif\]-->/ig;

while(match = regex2.exec(searchBody)){

   searchBody = searchBody.replace(match[0], "");

   currentCount += 1;

   if(currentCount >= 100)

   break;

}

currentCount = 0;

var regex2 = /<!\[if !vml\]>(.*?)<!\[endif\]>/ig;

while(match = regex2.exec(searchBody)){

   searchBody = searchBody.replace(match[0], match[1]);

   currentCount += 1;

   if(currentCount >= 100)

   break;

}



//gs.log("Create Morning Post: " + searchBody);



current.text = searchBody;



current.insert();



event.state="stop_processing";



function getEmailSYSID(emailuid) {

   var em = new GlideRecord('sys_email');

   em.addQuery('uid', emailuid);

   em.query();

   while(em.next()) {

   //we execute the return only within a certain time difference between the creation of the attachment and now (in seconds)

   var dif = gs.dateDiff(em.sys_created_on, gs.nowNoTZ(), true);

   //gs.log("difference: " + dif + "eid: " + em.sys_id + " uid: " + em.uid); //debug

   if(dif < 300 && dif > -300){

   //gs.log('passed dif if: ' + em.sys_id + " uid: " + em.uid); //debug

   return em.sys_id;

   }

   }

   return "";

}




function findAndReplaceImage(imageText){

   var img = imageText;

   var imgName = img.substring(4, img.search(/@/i));

   var imgCode = "sys_attachment.do?sys_id=";

   //Get the sys_id of the attachment

   var gr = new GlideRecord("sys_attachment");

   gr.addQuery("file_name", imgName);

   gr.addQuery("table_sys_id", getEmailSYSID(email.uid));

   gr.query();

   if (gr.next()) {

   imgCode += gr.sys_id;

   }

   searchBody = searchBody.replace(img, imgCode);

}

At the time of writing this (3+ years ago) the UID of the email was the ONLY way to find the record in the table to get its sys_id. If you find a better way let me know.

Keep in mind that if you test the same email multiple times all of the attempts after the first will not have there pics attached because they were all moved to the first KB article.

thanks your last sentence saved me some trouble.

Here is the solution, just updated the 'getEmailSYSID' function a little bit.

function getEmailSYSID(emailuid) {


   var em = new GlideRecord('sys_email');


   em.addQuery('uid', emailuid);


   em.query();


   while(em.next()) {


       //we execute the return only within a certain time difference between the creation of the attachment and now (in seconds)


       var dif = gs.dateDiff(em.sys_created_on, gs.nowNoTZ(), true);


       if(dif < 300 && dif > -300){


           return em.sys_id;


       }


   }


   return "";


}

I haven't tried, but could you not search for the message_id? is this not included when using email.message_id?

DrewW · ‎04-09-2014

Searching the message ID mite work but I seam to remember that support told me the UID was the best method at the time.

Hey how did you get the code to show formatted?

conmic · ‎04-09-2014

On the right upper side of the reply box you have 'use advanced editor'

and then you have more options, one of em called 'insert'

Well, thank you again I'll play a bit around with the message_id later, but this seems now to work perfectly!

Perhaps you can update your correct answer.

Kind Regards

Hi,

We are facing the same issue that images are not getting displayed. sys_id is bla@nk in the image src

Were you able to find any fix for this issue.

Thanks
