Er zijn meerdere manieren om HTML-tabellen te converteren into CSV's en Excel-spreadsheets gebruiken GrabzIt's Python API, hier worden enkele van de meest nuttige technieken beschreven. Onthoud echter voordat u begint dat nadat u de URLToTable, HTMLToTable or FileToTable methoden de Save or SaveTo methode moet worden aangeroepen om de tabel vast te leggen. Als u snel wilt zien of deze service geschikt is voor u, kunt u een proberen live demo van het vastleggen van HTML-tabellen van een URL.
Het onderstaande codefragment converteert automatisch de eerste HTML-tabel in een opgegeven webpagina intoa CSV-document dat vervolgens kan worden gedownload of ontleed.
grabzIt.URLToTable("https://www.tesla.com") # Then call the Save or SaveTo method
grabzIt.HTMLToTable("<html><body><table><tr><th>Name</th><th>Age</th></tr> <tr><td>Tom</td><td>23</td></tr><tr><td>Nicola</td><td>26</td></tr> </table></body></html>") # Then call the Save or SaveTo method
grabzIt.FileToTable("tables.html") # Then call the Save or SaveTo method
Standaard converteert dit de eerste tabel die wordt geïdentificeerd inteen tafel. De tweede tabel op een webpagina kan echter worden geconverteerd door een 2 door te geven aan de tableNumberToInclude
attribuut.
from GrabzIt import GrabzItTableOptions from GrabzIt import GrabzItClient grabzIt = GrabzItClient.GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret") options = GrabzItTableOptions.GrabzItTableOptions() options.tableNumberToInclude = 2 grabzIt.URLToTable("https://www.tesla.com", options) # Then call the Save or SaveTo method grabzIt.SaveTo("result.csv")
from GrabzIt import GrabzItTableOptions from GrabzIt import GrabzItClient grabzIt = GrabzItClient.GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret") options = GrabzItTableOptions.GrabzItTableOptions() options.tableNumberToInclude = 2 grabzIt.HTMLToTable("<html><body><table><tr><th>Name</th><th>Age</th></tr> <tr><td>Tom</td><td>23</td></tr><tr><td>Nicola</td><td>26</td></tr> </table></body></html>", options) # Then call the Save or SaveTo method grabzIt.SaveTo("result.csv")
from GrabzIt import GrabzItTableOptions from GrabzIt import GrabzItClient grabzIt = GrabzItClient.GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret") options = GrabzItTableOptions.GrabzItTableOptions() options.tableNumberToInclude = 2 grabzIt.FileToTable("tables.html", options) # Then call the Save or SaveTo method grabzIt.SaveTo("result.csv")
U kunt ook de targetElement
kenmerk dat ervoor zorgt dat alleen tabellen binnen het opgegeven element-ID worden geconverteerd.
from GrabzIt import GrabzItTableOptions from GrabzIt import GrabzItClient grabzIt = GrabzItClient.GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret") options = GrabzItTableOptions.GrabzItTableOptions() options.targetElement = "stocks_table" grabzIt.URLToTable("https://www.tesla.com", options) # Then call the Save or SaveTo method grabzIt.SaveTo("result.csv")
from GrabzIt import GrabzItTableOptions from GrabzIt import GrabzItClient grabzIt = GrabzItClient.GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret") options = GrabzItTableOptions.GrabzItTableOptions() options.targetElement = "stocks_table" grabzIt.HTMLToTable("<html><body><table id='stocks_table'><tr><th>Name</th><th>Age</th></tr> <tr><td>Tom</td><td>23</td></tr><tr><td>Nicola</td><td>26</td></tr> </table></body></html>", options) # Then call the Save or SaveTo method grabzIt.SaveTo("result.csv")
from GrabzIt import GrabzItTableOptions from GrabzIt import GrabzItClient grabzIt = GrabzItClient.GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret") options = GrabzItTableOptions.GrabzItTableOptions() options.targetElement = "stocks_table" grabzIt.FileToTable("tables.html", options) # Then call the Save or SaveTo method grabzIt.SaveTo("result.csv")
Als alternatief kunt u alle tabellen op een webpagina vastleggen door waar door te geven includeAllTables
kenmerk, dit werkt echter alleen met de formaten XLSX en JSON. Met deze optie wordt elke tabel in een nieuw blad in de gegenereerde spreadsheetwerkmap geplaatst.
from GrabzIt import GrabzItTableOptions from GrabzIt import GrabzItClient grabzIt = GrabzItClient.GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret") options = GrabzItTableOptions.GrabzItTableOptions() options.format = 'xlsx' options.includeAllTables = True grabzIt.URLToTable("https://www.tesla.com", options) # Then call the Save or SaveTo method grabzIt.SaveTo("result.xlsx")
from GrabzIt import GrabzItTableOptions from GrabzIt import GrabzItClient grabzIt = GrabzItClient.GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret") options = GrabzItTableOptions.GrabzItTableOptions() options.format = 'xlsx' options.includeAllTables = True grabzIt.HTMLToTable("<html><body><table><tr><th>Name</th><th>Age</th></tr> <tr><td>Tom</td><td>23</td></tr><tr><td>Nicola</td><td>26</td></tr> </table></body></html>", options) # Then call the Save or SaveTo method grabzIt.SaveTo("result.xlsx")
from GrabzIt import GrabzItTableOptions from GrabzIt import GrabzItClient grabzIt = GrabzItClient.GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret") options = GrabzItTableOptions.GrabzItTableOptions() options.format = 'xlsx' options.includeAllTables = True grabzIt.FileToTable("tables.html", options) # Then call the Save or SaveTo method grabzIt.SaveTo("result.xlsx")
Met behulp van de HTML-tabelconversieservice van Python en GrabzIt kunt u HTML-tabellen converteren into JSON. De eerste stap, zoals hieronder weergegeven, moet worden opgegeven json
in de opmaakparameter. We krijgen dan de JSON string synchroon met de SaveTo
methode, kunt u vervolgens uw favoriete JSON-parser voor Python gebruiken om de JSON te converteren string intoa object.
from GrabzIt import GrabzItTableOptions from GrabzIt import GrabzItClient grabzIt = GrabzItClient.GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret") options = GrabzItTableOptions.GrabzItTableOptions() options.format = "json" options.tableNumberToInclude = 1 grabzIt.URLToTable("https://www.tesla.com", options) json = grabzIt.SaveTo()
from GrabzIt import GrabzItTableOptions from GrabzIt import GrabzItClient grabzIt = GrabzItClient.GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret") options = GrabzItTableOptions.GrabzItTableOptions() options.format = "json" options.tableNumberToInclude = 1 grabzIt.HTMLToTable("<html><body><table><tr><th>Name</th><th>Age</th></tr> <tr><td>Tom</td><td>23</td></tr><tr><td>Nicola</td><td>26</td></tr> </table></body></html>", options) json = grabzIt.SaveTo()
from GrabzIt import GrabzItTableOptions from GrabzIt import GrabzItClient grabzIt = GrabzItClient.GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret") options = GrabzItTableOptions.GrabzItTableOptions() options.format = "json" options.tableNumberToInclude = 1 grabzIt.FileToTable("tables.html", options) json = grabzIt.SaveTo()
U kunt een aangepaste identificatie doorgeven aan de tafel methoden zoals hieronder weergegeven, wordt deze waarde vervolgens teruggegeven aan uw GrabzIt Python-handler. Deze aangepaste identificatie kan bijvoorbeeld een database-identificatie zijn, waardoor een screenshot kan worden gekoppeld aan een bepaald database-record.
from GrabzIt import GrabzItTableOptions from GrabzIt import GrabzItClient grabzIt = GrabzItClient.GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret") options = GrabzItTableOptions.GrabzItTableOptions() options.customId = "123456" grabzIt.URLToTable("https://www.tesla.com", options) # Then call the Save method grabzIt.Save("http://www.example.com/handler.py")
from GrabzIt import GrabzItTableOptions from GrabzIt import GrabzItClient grabzIt = GrabzItClient.GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret") options = GrabzItTableOptions.GrabzItTableOptions() options.customId = "123456" grabzIt.HTMLToTable("<html><body><h1>Hello World!</h1></body></html>", options) # Then call the Save method grabzIt.Save("http://www.example.com/handler.py")
from GrabzIt import GrabzItTableOptions from GrabzIt import GrabzItClient grabzIt = GrabzItClient.GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret") options = GrabzItTableOptions.GrabzItTableOptions() options.customId = "123456" grabzIt.FileToTable("example.html", options) # Then call the Save method grabzIt.Save("http://www.example.com/handler.py")
