We need to convert/provide our html-based in-app HelpSystem to an on-disc pdf for the client to view outside of the application.
I'm trying to use wkhtmltopdf with a very basic file (3 frames with links to simple .html files) but getting an empty .pdf when I run the following from the command line:
wkhtmltopdf "C:\Program Files (x86)\wkhtmltopdf\index.html" "c:\delme\test.pdf"
I know frames are somewhat deprecated but it’s what I’ve got to deal with. Are the frames causing the empty pdf?
Index.html:

<h2>The blockquote Element</h2>
<p>The blockquote element specifies a section that is quoted from another source.</p>
<p>Here is a quote from WWF's website:</p>
<blockquote cite="http://www.worldwildlife.org/who/index.html">For 50 years, WWF has been protecting the future of nature. The
world’s leading conservation organization, WWF works in 100 countries and is supported by 1.2 million members in the United
States and close to 5 million globally.</blockquote>
<p>
<b>Note:</b> Browsers usually indent blockquote elements.</p>
<h2>The q Element</h2>
<p>The q element defines a short quotation.</p>
<p>WWF's goal is to:
<q>Build a future where people live in harmony with nature.</q> We hope they succeed.</p>

Taken from the official wkhtmltopdf issues area from a code project member’s answer; emphasis is mine:
wkhtmltopdf calculates the TOC based on the H* (e.g. H1, H2 and so on)
tags in the supplied documents. It does not recurse into frames and
iframes.. It will nest dependend on the number, to make sure that it
does the right thing, it is good to make sure that you only have
tags under a tag and not for some k larger
then 1. 2000+ files sounds like a lot. You might run out of memory
while converting the output. If it does not work for you.. you could
try using the switch to dump the outline to a xml file, to see what it
would but into a TOC.

for other areas of a web page it is simple to mark up; i.e. navigation element, header, footer, sidebar
Not so with mainContentOfPage; I've seen a number of different ways to implement this, most recently (and I found this one to be the most strange) on schema.org itself:
<div itemscope itemtype="http://schema.org/Table">
<meta itemprop="mainContentOfPage" content="true"/>
<h2 itemprop="about">list of presidents</h2>
<table>
<tr><th>President</th><th>Party</th><tr>
<tr>
<td>George Washington (1789-1797)</td>
<td>no party</td>
</tr>
<tr>
<td>John Adams (1797-1801)</td>
<td>Federalist</td>
</tr>
...
</table>
</div>
I could use some examples; the main content of my page is in this case a search results page, but I would plan to use this on other pages too (homepage, product page, etc.)
Edit, I found some more examples:
Would this be valid? I found this on a blog:
<div id="main" itemscope itemtype="http://schema.org/WebPageElement" itemprop="mainContentOfPage">
<p>The content</p>
</div>
I also found this even simpler example on another blog (might be too simple?):
<div id="content" itemprop="mainContentOfPage">
<p>The content</p>
</div>
The mainContentOfPage property can be used on WebPage and expects a WebPageElement as value.
But Table is not a child of WebPage and true is not an expected value. So this example is in fact strange, as it doesn’t follow the specification.
A parent WebPage should use Table as value for mainContentOfPage:
<body itemscope itemtype="http://schema.org/WebPage">
<div itemprop="mainContentOfPage" itemscope itemtype="http://schema.org/Table">
</div>
</body>
EDIT: Update
Your second example is the same like mine, it just uses the more general WebPageElement instead of Table. (Of course you’d still need a parent WebPage item, like in my example.)
Your third example is not in line with schema.org’s definition, as the value is Text and not the expected WebPageElement (or child) item.
A valid option would be:
<body itemscope itemtype="http://schema.org/WebPage">
<main itemprop="mainContentOfPage" itemscope itemtype="http://schema.org/WebPageElement">
<div itemprop="about" itemscope="" itemtype="http://schema.org/Thing">
<h1 itemprop="name">whatever</h1>
</div>
</main>
</body>
Of course you may add related properties to top-level or nested elements, and change Thing into any other item type listed at Full Hierarchy. I also recommend to use mainEntity, documentation still doesn't clarify if it's really necessary, but according to 1st example here, using WebPage you may want to specify a mainEntity:
<body itemscope itemtype="http://schema.org/WebPage">
<header><h1 itemscope itemprop="mainEntity" itemtype="http://schema.org/Thing">whatever</h1></header>
<main itemprop="mainContentOfPage" itemscope itemtype="http://schema.org/WebPageElement">
<div itemprop="about" itemscope="" itemtype="http://schema.org/Thing">
<h2 itemprop="name">whatever</h2>
</div>
</main>
</body>
Cannot tell if also this would be valid:
<body itemscope itemtype="http://schema.org/WebPage">
<main itemprop="mainContentOfPage" itemscope itemtype="http://schema.org/WebPageElement">
<div itemprop="mainEntity" itemscope="" itemtype="http://schema.org/Thing">
<h1 itemprop="name">whatever</h1>
</div>
</main>
</body>
Documentation doesn't say nothing about setting mainEntity to nested items.
In any case, consider that "[...] Every web page is implicitly assumed to be declared to be of type WebPage [...]" as stated in WebPage description, and use of HTML tags as <main>, <footer> or <header> already gives information about what type of elements are used in a page. So if actually you do not need to add relevant information to those elements or to your web page itself, with a proper use of HTML tags you could easily do without mainContentOfPage or even WebPage.
I am trying to search the webpage for particular strings, and I am using the following code:
strPageContent = appIE.document.documentElement.InnerHTML
However, the page is quite complicated and has got a lot of frames and framesets, and the command above returns only the contents of some parents tag. How can I access the contents of the particular div element - please see the code below:
<html>
<head>...</head>
<frameset id="NavContent_Workhorse" frameborder="0" framespacing="0" rows="*,0">
<frameset id="Nav_Content" border="3" frameborder="1" framespacing="3" cols="240,*">
<frame name="nav" src="/interface/sidebar/sidebar.def" scrolling="no">
<frame name="content" src="/interface/home.def" frameborder="1" border="3" marginheight="0" marginwidth="0" scrolling="no">
#document
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html lang>
<head> … </head>
<body onload="LoadAdd();">
<div class="PageTitle" id="PageTitle">...</div>
<div class="ToolBar" id="PageBody">...</div>
<div id="error" class="none"> … </div>
<div id="content" style="display: block; height: 445px;">
<form id="frmUSR" method="post" target="workhorse" onsubmit="return false;" action="/setup/users_groups/users/insert.sdl?parentid=14">
<div id="wiz_1" class="wiz_vis">
<table class="frmTbl">
<thead class="title">
<tr>
<th class="label">
TEXT THAT I AM LOOKING FOR
</th>
Thanks in advance!
Edit:
I forgot to add that I did try the code below, but I get a null value
Set div = appIE.document.getElementById("wiz_1")
Edit 2:
The purpose of the script is to automate filling out the user creation forms on my company's system (webpage UI). I don't know why, but I cannot get a reference to anything that is below the main <frameset id="Nav_Content" border="3". I keep getting null values.
You can access the content of an element with a particular ID inside a frame like this:
Set frame = appIE.Document.parentWindow.window.frames("content")
Set div = frame.document.getElementById("wiz_1")
WScript.Echo div.innerHTML
WScript.Echo div.innerText
I've recently decided to update a website by adding rich snippets - microdata.
The thing is I'm a newbie to this kind of things and I'm having a small question about this.
I'm trying to define the Organization as you can see from the code below:
<div class="block-content" itemscope itemtype="http://schema.org/Organization">
<p itemprop="name">SOME ORGANIZATION</p>
<p itemprop="address" itemscope itemtype="http://schema.org/PostalAddress">
<span itemprop="streetAddress">Manufacture Street no 4</span>,
<span itemprop="PostalCode">4556210</span><br />
<span itemprop="addressLocality">CityVille</span>,
<span itemprop="addressCountry">SnippetsLand</span></p>
<hr>
<p itemprop="telephone">0444 330 226</p>
<hr>
<p>info#snippets.com</p>
</div>
Now, my problems consists in the following: I'd like to also tag the LOGO in order to make a complete Organization profile, but the logo stands in the header of my page, and the div I've posted above stands in the footer and the style/layout of the page doesnt permit me to add the logo in here and also make it visible.
So, how can I solve this thing? What's the best solution?
Thanks.
You can use the itemref attribute.
Give your logo in the header an id and add the corresponding itemprop:
<img src="acme-logo.png" alt="ACME Inc." itemprop="logo" id="logo" />
Now add itemref="logo" to your div in the footer:
<div class="block-content" itemscope itemtype="http://schema.org/Organization" itemref="logo">
…
</div>
If this is not possible in your case, you could "duplicate" the logo so that it’s included in your div, but not visible. Microdata allows meta and link elements in the body for this case. You should use the link element, as http://schema.org/Organization expects an URL for the logo property. (Alternatively, add it via meta as a separate ImageObject).
<div class="block-content" itemscope itemtype="http://schema.org/Organization">
…
<link itemprop="logo" src="logo.png" />
…
</div>
Side note: I don’t think that you are using the hr element correctly in your example. If you simply want to display a horizontal line, you should use CSS (e.g. border-top on the p) instead.
Dan, you could simply add in the logo schema with this code:
<img itemprop="logo" src="http://www.example.com/logo.png" />
So in your example, you could simply tag it as:
<div class="block-content" itemscope itemtype="http://schema.org/Organization">
<p itemprop="name">SOME ORGANIZATION</p>
<img itemprop="logo" src="http://www.example.com/logo.png" />
<p itemprop="address" itemscope itemtype="http://schema.org/PostalAddress">
<span itemprop="streetAddress">Manufacture Street no 4</span>,
<span itemprop="PostalCode">4556210</span><br />
<span itemprop="addressLocality">CityVille</span>,
<span itemprop="addressCountry">SnippetsLand</span></p>
<hr>
<p itemprop="telephone">0444 330 226</p>
<hr>
<p>info#snippets.com</p>
</div>
I believe that should work for your particular case and it won't actually show the logo and you wouldn't have to mark up the logo separately. Hope that helps.
I am trying to get the value of an element attribute from this site via importXML in Google Spreadsheet using XPath.
The attribute value i seek is content found in the <span> with itemprop="price".
<div class="left" style="margin-top: 10px;">
<meta itemprop="currency" content="RON">
<span class="pret" itemprop="price" content="698,31 RON">
<p class="pret">Pretul tau:</p>
698,31 RON
</span>
...
</div>
I can access <div class="left"> but i can't get to the <span> element.
Tried using:
//span[#class='pret']/#content i get #N/A;
//span[#itemprop='price']/#content i get #N/A;
//div[#class='left']/span[#class='pret' and #itemprop='price']/#content i get #N/A;
//div[#class='left']/span[1]/#content i get #N/A;
//div[#class='left']/span/text() to get the text node of <span> i get #N/A;
//div[#class='left']//span/text() i get the text node of a <span> lower in div.left.
To get the text node of <span> i have to use //div[#class='left']/text(). But i can't use that text node because the layout of the span changes if a product is on sale, so i need the attribute.
It's like the span i'm looking for does not exist, although it appears in the development view of Chrome and in the page source and all XPath work in the console using $x("").
I tried to generate the XPath directly form the development tool by right clicking and i get //*[#id='produs']/div[4]/div[4]/div[1]/span which does not work. I also tried to generate the XPath with Firefox and plugins for FF and Chrome to no avail. The XPath generated in these ways did not even work on sites i managed to scrape with "hand coded XPath".
Now, the strangest thing is that on this other site with apparently similar code structure the XPath //span[#itemprop='price']/#content works.
I struggled with this for 4 days now. I'm starting to think it's something to do with the auto-closing meta tag, but why doesn't this happen on the other site?
Perhaps the following formulas can help you:
=ImportXML("http://...","//div[#class='product-info-price']//div[#class='left']/text()")
Or
=INDEX(ImportXML("http://...","//div[#class='product-info-price']//div[#class='left']"), 1, 2)
UPDATE
It seems that not properly parse the entire document, it fails. A document extraction, something like:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<div class="product-info-price">
<div class="left" style="margin-top: 10px;">
<meta itemprop="currency" content="RON">
<span class="pret" itemprop="price" content="698,31 RON">
<p class="pret">Pretul tau:</p>
698,31 RON
</span>
<div class="resealed-info">

</form>
</div>
</div>
</html>
works with the following XPath query:
"//div[#class='product-info-price']//div[#class='left']//span[#itemprop='price']/#content"
UPDATE
It occurs to me that one option is that you can use Apps Script to create your own ImportXML function, something like:
/* CODE FOR DEMONSTRATION PURPOSES */
function MyImportXML(url) {
var found, html, content = '';
var response = UrlFetchApp.fetch(url);
if (response) {
html = response.getContentText();
if (html) content = html.match(/<span class="pret" itemprop="price" content="(.*)">/gi)[0].match(/content="(.*)"/i)[1];
}
return content;
}
Then you can use as follows:
=MyImportXML("http://...")
At this time, the referred web page in the first link doesn't include a span tag with itemprop="price", but the following XPath returns 639
//b[#itemprop='price']
Looks to me that the problem was that the meta tag was not XHTML compliant but now all the meta tags are properly closed.
Before:
<meta itemprop="currency" content="RON">
Now
<meta itemprop="priceCurrency" content="RON" />
For web pages that are not XHTML compliant, instead of IMPORTXML another solution should be used, like using IMPORTDATA and REGEXEXTRACT or Google Apps Script, the UrlFetch Service and the match JavasScript function, among other alternatives.
Try smth like this:
print 'content by key',tree.xpath('//*[#itemprop="price"]')[0].get('content')
or
nodes = tree.xpath('//div/meta/span')
for node in nodes:
print 'content =',node.get('content')
But i haven't tried that.
I need some help getting some rich snippets to my site
I inserted the review microdata following the instructions given on schema.org here http://schema.org/docs/gs.html#advanced_missing using the star-image for rating and the text for review count, but testing it with the test tool it showed nothing.
Example page where we use the microdata for the reviews.
and here is what I used
<div itemprop="reviews" itemscope itemtype="http://schema.org/AggregateRating">
<img src="/images/stars/4.5.gif" border=0>
<meta itemprop="ratingValue" content="4.5" />
<meta itemprop="bestRating" content="5" />
<BR>
<span class="bottomnavfooter">
<A HREF="javascript:an();">Read (<span itemprop="ratingCount">70</span>) Reviews</A
</span>
</div>
I then created a static test page and made some change using instructions Google provided here http://www.google.com/support/webmasters/bin/answer.py?answer=172705 (which is different from what I found on schema.org!!) but still the test returned only product name not the price or the reviews.
Here is my test page - Can you please see where I'm going wrong
Thanks much!!
The above code snippet will fail because it has an itemprop for aggregateRating, but isn't enclosed in an itemscope. It also doesn't help that your final anchor close tag is missing a >, but I guess that was just an accident when you were copying the code into SO.
The other problem mainly brought about because the example on the schema.org site is wrong (I have filed a bug report on this). They mention itemprop="reviews" instead of itemprop="aggregateRating". The code should look more like the following:
<div itemscope itemtype="http://schema.org/Offer">
<span itemprop="name">Ray-Ban 2132 New Wayfarer Sunglasses</span>
<div itemprop="aggregateRating" itemscope itemtype="http://schema.org/AggregateRating">
<img src="/images/stars/4.5.gif" border=0>
<meta itemprop="ratingValue" content="4.5" />
<meta itemprop="bestRating" content="5" />
<br />
<span class="bottomnavfooter">
Read (<span itemprop="ratingCount">70</span>) Reviews
</span>
