*html_get_attribute Function

Syntax

Arguments

htmlCharacter

An HTML snippet.

attribute

The name of the attribute to find.

Description

Get the first matching attribute from passed HTML snippet (returns empty string if none was found).

Example

This is a quick way to extract an attribute value from some HTML markup. Consider the following HTML markup:

dim html as c 
html = <<%html%
     id="GRID1.V.R2.PICTURE1"   
    onmouseover="$('bp').src=img;"   
    style="height: 1in; cursor: pointer;" 
    src="pictures/5.jpg"  
    title="pictures/5.jpg"  
    onerror="{grid.object}._executeEvent('onImageError',{element: this});"  />
%html%

Say you wanted to extract the 'src' attribute from this HTML. A simple string search for the text 'src=' would be wrong because it would get confused by the code for the onmouseover event handler.

dim attr as c 
attr = *HTML_GET_ATTRIBUTE(html,"src")
? = src="pictures/5.jpg"
