Problem with Z tag (1 Viewer)

Khurram · February 2, 2009

I have the following grabber

Code:

<?xml version="1.0" encoding="utf-8"?>
<Grabber>
	<Info availableDays="7" timezone="South Africa Standard Time" version="2.0"/>
	<Channels>
		<Channel id="mneteast@mnetafrica.com" siteId="229"/>
		<Channel id="mm1@mnet.co.za" siteId="225"/>
	</Channels>
	<Listing type="Html">
		<Site url="http://beta.mnetafrica.com/Schedule.aspx?channel=[ID]&amp;days=1" post="" external="false" encoding=""/>
		<Html>
			<Template name="default" start="&lt;table cellspacing=&quot;0&quot; border=&quot;0&quot; id=&quot;ctl00_body_ctl00_dg1&quot; style=&quot;border-collapse:collapse;&quot;&gt;" end="&lt;/table&gt;">
				<SectionTemplate tags="TS">
					<TemplateText>
&lt;td class=&quot;txt_time&quot; style=&quot;width:60px;&quot;&gt;&lt;#START&gt;&lt;/td&gt;&lt;td class=&quot;txt_descrip&quot; valign=&quot;top&quot; style=&quot;height:40px;width:690px;&quot;&gt;&lt;span class=txt_showTitle&gt;&lt;#TITLE&gt;&lt;/span&gt;&lt;br/&gt;&lt;z(&gt;'S&lt;#SEASON&gt;/E&lt;#EPISODE&gt; - &lt;#SUBTITLE&gt;'. &lt;/z)?&gt;&lt;#DESCRIPTION&gt;&lt;/td&gt;&lt;td title=&quot;Age Restriction&quot; class=&quot;link_rating&quot; style=&quot;width:43px;&quot;&gt;&lt;a href=# onclick=OpenAgeRestriction(1);return false; class=link_rating&gt; PG/13                                            &lt;/a&gt;&lt;/td&gt;
          </TemplateText>
				</SectionTemplate>
			</Template>
		</Html>
	</Listing>
</Grabber>

The Z tag in the template does not work. The html for the description is sometimes preceeded by season/episode/subtitle information. I thought I could capture this information using a Z tag as this information is always in the same format and enclosed in single quotes, for example:

'S1/E1 - Part I'. description starts from here

But WebEPG is always including the season/episode/subtitle information in the description. What am I doing wrong?

I am generally confused about the Z tag. From what I understand, it is supposed to match 0 or 1 occurrances of the enclosing html. So for example, if the templates contains the following:

Code:

<z(><dt>Starring</dt>
	<dd>name 1, name 2</dd></z)?>
				 
<z(><dt>Director</dt>
	<dd>some name</dd></z)?>
	 
       <dt>Description</dt>
	<dd><#Description></dd>

Then the code will match the following:

1) One dt/dd pair, "Description" in the dt tag.
2) Two dt/dd pairs, either "Starring" or "Director" in first dt tag and "Description" in second dt tag.
3) Three dt/dd pairs, "Starring" in first dt tag, "Director" in second dt tag and "Description" in third dt tag.

Is this reasoning correct?

Hi Khurram,

Generally that would but the idea. However, the Z tag builds a Regular Expression, so it could depend a little on what comes before and after. See the concept of greediness (Regex Tutorial - The Question Mark Makes the Preceding Token Optional). Also WebEPG does not make a difference between these two tags <dt> and <dd>.

if <dt> or <dd> = d
and </dt> or </dd> = D

Then the regex looks like "(dDdD)?(dDdD)?dDdD" and this is going to be matched to a long string from the HTML source using the same system.

The Regex Tutorial - The Question Mark Makes the Preceding Token Optional site is very useful. If I am not mistaken, the site's link is in the wiki also where you talk about the z-tag.

Lets say I have the following 2 pages:
HBO South Asia | Hollow Man 2. The HTML containing the information is

Code:

</ul>
</div>
<dl class="info">
    <dt>Starring</dt>
    <dd>Christian Slater, Peter Facinelli, Laura Regan</dd>
    <dt>Genre</dt>
    <dd>Action, Adventure</dd>
    <dt>Duration</dt>
    <dd>1 hr 22 min</dd>
</dl>
</div>
<div class="synopsis">
    <p>some description.</p>
</div>
<div class="legal">

and
HBO South Asia | Single White Female. The HTML containing the information is

Code:

</ul>
</div>
<dl class="info">
    <dt>Starring</dt>
    <dd>Jennifer Jason Leigh, Bridget Fonda, Steven Weber</dd>
    <dt>Directed</dt>
    <dd>Barbet Schroeder</dd>
    <dt>Genre</dt>
    <dd>Suspense, Thriller</dd>
    <dt>Duration</dt>
    <dd>1 hr 35 min</dd>
</dl>
</div>
<div class="synopsis">
    <p>some description</p>
</div>
<div class="legal">

My grabber template is

Code:

<Template name="Details" start="Add to MyHBO</a></li>" end="<div class="legal">">
	<SectionTemplate tags="UDP">
		<TemplateText>
			</ul>
				</div>
				<dl class="info">
					<z(><dt><*MATCH></dt>
						<dd><*VALUE></dd></z)?>
					<z(><dt><*MATCH></dt>
						<dd><*VALUE></dd></z)?>
					<dt><*MATCH></dt>
					<dd><*VALUE></dd>
					<dt><*MATCH></dt>
					<dd><*VALUE></dd>
				</dl>
			</div>
			<div class="<*MATCH>">
				<p><*VALUE></p>
			</div>
		</TemplateText>
		<MatchList>
			<Match field="#ACTORS" match="Starring" />
			<Match field="#DIRECTOR" match="Directed" />
			<Match field="#GENRE" match="Genre" />
			<Match field="#DURATION" match="Duration" />
			<Match field="#DESCRIPTION" match="synopsis" />
		</MatchList>
	</SectionTemplate>
</Template>

As far as I can tell, the page tagMap has 1 match with the template tagMap, but I get wierd behavior with the #DESCRIPTION token. If there is a match with 1 of the z-tags, #DESCRIPTION is ok. But if there are no matches with either of the z-tags, #DESCRIPTION is blank. I have tried debugging it but got the sqlite.dll error again even though sqlite.dll is in the proper folder (...mediaportal\WebEPG\WebEPG-xmltv\bin\Debug).
