Read data from html Tables from raw HTML source

Gianni · February 23, 2015

This is for extraction of data from HTML tables to an array.
It uses an raw html source file as input, and does not relies on any browser.
You can get the source of the html using commands like InetGet(), InetRead(), _INetGetSource(), _IEDocReadHTML() for example, or load an html file from disc as well.
It also takes care of the data position in the table due to rowspan and colspan trying to keep the same layout in the generated array.
It has the option to fill the cells in the array corresponding with the "span" zones all with the same value of the first "span" cell of the corresponding area.

Edited June 26, 2016 by Chimp
Added the _HTML_Filter() function in the UDF and updated the example script

Gianni · June 28, 2015

After seeing the function __HTML_Filter() in this topic by Stilgar (https://www.autoitscript.com/forum/topic/124330-_htmlau3-v101/) I thought I'd include that function also in this script.
the purpose of that function is to clean the extracted data from the table by those codes that are not visible in the browser but are visible as code "dirty" in the data when they are picked up from the table.

Updated the udf and the example script in first post.

To see the difference in the extracted data with or without the use of the HTML_Filter() function, just extract the table data from the example page by clicking on the "Preview array" button with the filter CheckBox "tags to entities" one time unchecked and then checked instead.

Hi Chimp!
Thanks a lot for your example - it saved me a lot work!
I had to parse a table with almost 1400 rows (and lots of rowspans) in an 1.5MB HTML file, and got some performance issues. Here is how I solved them:
First, I adapted the HTML tag position search in _ParseTags to search starting on the last tag found position, so StringInStr doesn't need to count thousands of "<tr" tags every iteration. Then, _ArraySort failed (too many rows...). So, to get the tag list pre-sorted, I search for the first opening and first closing tag. If the opening is before the closing, write to $aThisTagsPositions and find the next opening; if the closing is before the next opening, write to $aThisTagsPositions and find the next closing.

This made it possible to read that huge HTML file in less than 90 seconds.

Just replace the code on lines 208-216 with this:

Local $iNextOpenPosition = StringInStr($sHtml, $sOpening, 0, 1)
        Local $iNextClosePosition = StringInStr($sHtml, $sClosing, 0, 1)
        Local $iOpenCount = 1

        ; 2) find in the HTML the positions of the $sOpening <tag and $sClosing </tag> tags
        For $i = 1 To $iNrOfThisTag * 2 ;search all the opening and closing tags
            If ($iNextOpenPosition < $iNextClosePosition) And $iNextOpenPosition <> 0 Then
                $aThisTagsPositions[$i][0] = $iNextOpenPosition
                $aThisTagsPositions[$i][1] = $sOpening ; it marks which kind of tag is this
                $aThisTagsPositions[$i][2] = $iOpenCount; nr of this tag
                $iOpenCount += 1
                $iNextOpenPosition = StringInStr($sHtml, $sOpening, 0, 1, $aThisTagsPositions[$i][0] + 1)
            Else
                $aThisTagsPositions[$i][0] = $iNextClosePosition + StringLen($sClosing) - 1
                $aThisTagsPositions[$i][1] = $sClosing ; it marks which kind of tag is this
                $iNextClosePosition = StringInStr($sHtml, $sClosing, 0, 1, $aThisTagsPositions[$i][0] + 1)
            EndIf
        Next

Sorry, I cannot find the link for downloanding the UDF library... someone could help me?

The first post contains the UDF's, which you simply cut&paste into a file yourself.
