Uncaught TypeError: Cannot read property 'getElementsByTagName' of undefined about sharepointplus

[Aymkdn]

Try to not use the minified version of the file in order to have a better
idea of the problem.

I have built an app that traverses the entire SharePoint and prepares an
excel report about the files and their metadata. Kind of like a snapshot of
the current file system on the SharePoint. Sometimes however I will get
this error, especially when I go around 100 000+ files on a very big
SharePoint site.

Any help will be great.

Ok, so the error is caused by the code on line 1160:
var err = res.getElementsByTagName("errorstring");

OK so look at your Web console to see the content of the server's response because this response returns an error that SharepointPlus is not able to handle.

I understand, I am looking at the console, but I don't see anything meaningful. It seems to be doing it on specific libraries. I think it has to do with the names of the lists... will try to debug it soon.

[Aymkdn]

If you use Firebug (or the Web console from a modern browser), you'll see the HTTP request sent to the server as well as the response. Check the content of this response to understand what is wrong with your data!

[docmbg]

Yeah, this is what I did. Turns out it's an xml parsing error.. some of the files have bad characters in the metadata, for instance, the author is all messed up in some docs. I don't think there's much I can do to parse the data as its done on the server-side. This is bad as queries for entire libraries will fail even if one file has bad characters in its metadata. Do you have any suggestions how I can parse the symbols on return?

[Aymkdn]

It's very difficult to deal with the weird signs in a response.... If you have an example of the returned content that is causing the issue ? Otherwise, try to see if Google/StackOverflow has some good advice regarding this kind of issue ?

[docmbg]

Unfortunately I cannot paste the entire xml response as it will reveal internal company information.
I can however show you an example of a bad character in a photo "comments" field. This is what I get in Firefox.

Google and Stack Overflow didn't turn up anything useful. I don't have access to the server-side, so I am kind of stuck right now. The solution is to go through all files and fix the metadata errors :(

Are you using Sharepoint 2013 or 2010 ?

[docmbg]

2010

[Aymkdn]

OK so try the native Sharepoint functions to see if the result is different (because it returns a JSON).
Below is an example of how to use it:

var ctx = new SP.ClientContext(_spPageContextInfo.webServerRelativeUrl);
 var items = ctx.get_web().get_lists().getByTitle('Name of Your List').getItems(new SP.CamlQuery());
 ctx.load(items, "Include(Title)");
 ctx.executeQueryAsync(function () {
      var listEnumerator = items.getEnumerator();
      while(listEnumerator.moveNext()) {
          var page = listEnumerator.get_current();
          console.log(page.get_item('Title')); // it will show the Title in the console
      }
 });

[docmbg]

That does work indeed. It does load the titles for the folders in the root of the library. I don't want to rewrite the application as it's got quite complex, and the information I extract is for records management purposes, hence skipping documents is not an option.

[Aymkdn]

No need to rewrite your application. You can just use this method to get the bad data and then you keep all the other part unchanged.

Ok, thank you! Much appreciated. I will have to do some digging around to mimic your get function and adapt it to return json instead of xml. I am not very familiar with the SharePoint javascript object model.. so it will take some time.
