Hi Florian,

I was hoping to see if a new web source fn could be added.

I want to parse this webpage [https://www.traxsource.com/search/artists?term=solomun](https://www.traxsource.com/search/artists?term=solomun) and get the first artist from that search result (mainly to get the artist number and use that info) therefore creating info for the [IndexUrl]=

So the code could look something like this:

This sets up the [PreIndexUrl] =

```
[PreIndexUrl]=https://www.traxsource.com/search/artists?term=%s

```

From that URL you can parse and create the new URL to be used for [IndexUrl]=

```
say "https://www.traxsource.com/artist/"
findline "<a href=\"/artist/"
findinline "<a href=\"/artist/"
sayuntil "/"
say "?cn=titles&ipp=100&ob=r_date&so=desc"

```

The above would create the URL:

```
https://www.traxsource.com/artist/6185/?cn=titles&ipp=100&ob=r_date&so=desc

```

Then use that parsed info [PreIndexUrl] = if applicable:

```
[IndexUrl] = PreIndexUrl

```

The reason for this is with the Traxsource website it's impossible to search releases based on the artist.

The code snippet/section altogether

```
[PreIndexUrl]=https://www.traxsource.com/search/artists?term=%s
say "https://www.traxsource.com/artist/"
findline "<a href=\"/artist/"
findinline "<a href=\"/artist/"
sayuntil "/"
say "?cn=titles&ipp=100&ob=r_date&so=desc"
[IndexUrl] = PreIndexUrl
```
