goalkicker.com and httpclient

[AIR]

Taking a break from working on nim-cocoa, I wanted to see how difficult it 
would be to pull down all of the free books from goalkicker.com

Got it working, just wondering if there was anything I could have done 
differently?
    
    
    import httpClient, htmlParser, xmltree, strutils, os
    
    let site = "https://books.goalkicker.com/";
    var client = newHttpClient()
    let src = client.getContent(site)
    var fileName: string
    
    createDir("books")
    
    let html = src.parseHtml
    
    for a in html.findAll("div"):
        if a.attr("class").startsWith("bookContainer"):
            for b in a.findAll("a"):
                let bookPage = client.getContent(site & b.attr("href"))
                let book = bookPage.parseHtml
                for c in book.findAll("div"):
                    if c.attr("id") == "header":
                        fileName = c.innerText.replace(" book",".pdf")
                        if fileName.startsWith('.'): fileName = "DOT" & fileName
                    if c.attr("id") == "footer":
                        var dlFile = c.innerText.split()[0]
                        var pdfFile = site & b.attr("href") & dlFile
                        echo "Downloading $#..." % [fileName]
                        client.downloadFile(pdfFile, "books/" & fileName)
    
    
    Run
