OK,
There are a few problems with your workflow that must be modified:
1- The get request node was unnecessary and I removed it.
2- The HTMLParser node was reading the initial URL not the result form HttpRetriever and I changed it.
3- When you get the href attribute by XPath node, there may be spaces in the URLs and you have to convert them to “%20” then you can use the URLs. So I added a string manipulation node after XPath node.
The rest of your workflow now works fine.
