Question: <https://en.wikipedia.org/wiki/List_of_largest_companies_by_revenue>

I am trying to find the names of the companies in order of revenue. It's a bit challenging because the titles all have differently formatted tags. If anyone could come up with a solution I'd be very grateful.

An example of my problem:

I'd like to match "Wal-Mart Stores Inc." and then "Sinopec Group" and so forth in order.

```
<td><a href="/wiki/Wal-Mart_Stores,_Inc." title="Wal-Mart Stores, Inc."class="mw-redirect">Wal-Mart Stores, Inc.</a></td>

```

...further in the document...

```
<td style="background: #ffffcc;"><a href="/wiki/Sinopec_Group" title="Sinopec Group" class="mw-redirect">Sinopec Group</a></td>

```

Thanks in advance.

Answer: 
First Error "caused by unable to verify the first certificate."
It looks like a typings proxy issue. Create a file called .typingsrc and place it in your home directory.

.typingsrc:

```
{
    "proxy": "http://<proxyURI>:<port>",
    "rejectUnauthorized": false
}

```

Second Error "Cannot find name 'Promise'." (etc.)

In your tsconfig.json file, under "compilerOptions" make "target": "es6"

```
"compilerOptions": {
    "outDir": "app",
    "target": "es6",
    "module": "commonjs",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "noImplicitAny": false,
    "suppressImplicitAnyIndexErrors": true
}

```
Maybe you aren't copy correctly all files, is easiest clone the project of github, like this:

```
git clone ./my-angular-app https://github.com/angular/quickstart

```

Is a example most complete, and helpful.
