ScrapeMultiple

Creates a fluent batch-scrape builder bound to a download task. The server request is sent only when the builder retrieves values.

Syntax

wds.ScrapeMultiple(@downloadTask)

Arguments

Name	Type	Description
@downloadTask	wds.DownloadTask	Supplies the task used by the later batch request. A null task remains unbound and later retrieval produces no values.

Returns

wds.ScrapeMultipleParams — use its AddScrapeParams, GetAll, and GetFirst methods to configure and retrieve the batch result.

See Scrape Paged for a complete ScrapeMultiple(...).AddScrapeParams(...).GetFirst(...) workflow.

Data Contracts

DownloadTask

Represents a download task that can be passed to MSSQL CLR functions.

Name	Type	Description
Server	ServerConfig	Server connection associated with the task.
Id	string	Download task identifier.
Url	string	Download task URL.

Validation requires Server, Id, and Url.

ServerConfig

API server configuration.

Name	Type	Description
Uri	Uri	API server URI.

Parse accepts wds://user:password@host:port?https=false, requires the wds scheme, and produces an HTTP URI unless https=true is supplied. Validation requires a URI.

BindDownloadTask(downloadTask) binds the parent task. AddScrapeParams(name, selector, attributeName) adds an extraction rule. GetAll(name) returns StringDataItems, and GetFirst(name) returns the first scraped string or null. Validation requires a bound task and validates all configured scrape parameters.

ScrapeParams

Defines one named field extracted from pages by selector, attribute, and optional conversion.

Name	Type	Description
Name	string	Output field name; names must be unique within a scrape request or Traversal level.
Selector	string	Selector for matching elements: `CSS: <selector>`, `XPATH: <selector>`, or `*` for the whole page.
AttributeName	string or null	Optional attribute; `val`, null, or empty returns inner text.
Convert	string or null	Optional conversion: `md()` for Markdown or `sr()` for main readable content.

Validation requires Name and Selector.

ScrapeResult

Represents values extracted for one named scrape field.

Name	Type	Description
Name	string	Optional field name copied from the matching `ScrapeParams` entry.
Values	array of string	Scraped values.

Validation requires Name and Values.
