Polycom PDS 2000 manual So on for each of the 9 iterations

Polycom Digital Signage Administrator Guide Data Source Tutorial

All of the remaining parsing rules in this tutorial are contained in this DataItem element.

In the HTML we've isolated, each cell of the table row contains the forecast for a day part. For example, the cell contains the forecast for "Today" (we've reformatted the code below to make it easier to see the forecast data):

<td width="11%"> <b>Today<br></b> <br> <imgsrc="/images/wtf/tsra70.jpg" width="55" height="58"

alt="Heavy Rain Chance for Measurable Precipitation 70%" title="Heavy Rain Chance for Measurable Precipitation 70%" > <br>

Heavy<br>Rain

<br>

Hi <font color="#FF0000">81°F</font> </td>

Each cell contains the day part's name (e.g. "Today"), the conditions (as the image's alternative text, e.g. "Heavy Rain Chance for Measurable Precipitation 70%"), the temperature (e.g. "81°F") and an image file (e.g. "/images/wtf/tsra70.jpg"). We'll extract each of these pieces of information in turn.

First, we need to isolate a given day part's table cell. We do this using a GetTag rule to isolate the text between the <td> and </td> tags:

<ParsingRule type="GetTag" Source="Source" result="DaySource"> <StartTag><td </StartTag> <EndTag></td></EndTag>

</ParsingRule>

The GetTag rule is index-aware, so because it is inside a <DataItem> element it will extract each table cell in turn. We used the <DataItem> element to apply its rules 9 times, so this GetTag rule will extract each of the 9 table cells. On the first iteration, the rule extracts the contents of the first table cell:

width="11%"><b>Today<br></b><br><img src="/images/wtf/tsra70.jpg" width="55" height="58" alt="Heavy Rain Chance for Measurable Precipitation 70%" title="Heavy Rain Chance for Measurable Precipitation 70%" ><br>Heavy<br>Rain<br>Hi <font color="#FF0000">81°F</font>

On the second iteration, the rule extracts the contents of the second table cell:

width="11%"><b>Tonight<br></b><br><img src="/images/wtf/ntsra80.jpg" width="55" height="58" alt="Heavy Rain Chance for Measurable Precipitation 80%" title="Heavy Rain Chance for Measurable Precipitation 80%" ><br>Heavy<br>Rain<br>Lo <font color="#0033CC">69°F</font>

And so on for each of the 9 iterations.
