Question

Use HtmlAgilityPack to divy up a document

Answer 1

A:

If i am right then , You can try one thing...as the same thing we do in sending custom html mails

Create a template of your html page with static contents.
Append identifiers for dynamic contents as you have stated [ReadMore] or {ReadmOre} or something similar to that.
Now read the template html file line by line and replace the identifiers with desired text.
Now save the entire string to a new html file or do whatever you want.

That's the plan. However, if I replace [Readmore] with a link and encapsulate the rest of the article from that point forward in a div tag, I will have unclosed tags. I need to remove the parents of [readmore] (if they exist) and then do it. I'm stuck on a consistent way to remove them.

Answer 2

+1 A:

Here is an XSLT solution:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"&gt;
 <xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

 <xsl:template match="node()|@*">
  <xsl:copy>
   <xsl:apply-templates select="node()|@*"/>
  </xsl:copy>
 </xsl:template>

 <xsl:template match="p[descendant::text()[. = '[READMORE]']]">
  <a href="#ReadmoreWrapper">READMORE</a>
  <div class="wrapper" id="#ReadmoreWrapper">
   <xsl:apply-templates select="following-sibling::node()" mode="copy"/>
  </div>
 </xsl:template>

 <xsl:template match=
  "node()[ancestor::p[descendant::text()[. = '[READMORE]']]
         or
          preceding::p[descendant::text()[. = '[READMORE]']]
          ]
  "/>

  <xsl:template match="node()|@*" mode="copy">
      <xsl:copy>
       <xsl:apply-templates select="node()|@*" mode="copy"/>
      </xsl:copy>
  </xsl:template>
</xsl:stylesheet>

when this transformation is applied on the following XML document:

<html>
<p>
  <font face="Georgia">
    <b>History</b><br/>&#xA0; <br/>Two of the polysaccharides used in the manufacture of...</font>
    <a title="PubMed" href="http://www.www.gov/pubmed/" target="_blank"/>
    <font face="Georgia">) and this web site for new development by...well as Self Affirmed Medical Food GRAS status.&#xA0;
    </font>
</p>

<p>
  <font face="Georgia">[READMORE]</font>
</p>

<p><font face="Georgia"><br/><strong>Proprietary Composition</strong><br/>
   <br/>The method in which soluble fibres are made into... REST OF ARTICLE...
   </font>
</p>

</html>

the wanted result is produced:

<html>
    <p>
        <font face="Georgia"><b>History</b><br/>  <br/>Two of the polysaccharides used in the manufacture of...</font>
        <a title="PubMed" href="http://www.www.gov/pubmed/" target="_blank"/>
        <font face="Georgia">) and this web site for new development by...well as Self Affirmed Medical Food GRAS status. 
    </font>
    </p>
    <a href="#ReadmoreWrapper">READMORE</a>
    <div class="wrapper" id="#ReadmoreWrapper">
        <p>
            <font face="Georgia"><br/><strong>Proprietary Composition</strong><br/><br/>The method in which soluble fibres are made into... REST OF ARTICLE...
   </font>
        </p>
    </div>
</html>

It appears like it would work, but I'm having parsing errors. It doesn't like ` ` in the text when Parsing as an XML Doc. Can the same XSLT Transform be done on a `HtmlAgilityPack.HtmlDocument`?"

I thought that HtmlAgilityPack produces an XML document. If this isn't true, you could convert its HTML DOM to XML tree (DOM) programmatically. When I wrote the transformation, I replaced all `@nbsp;` and also all unclosed tags like `<br>` with `<br />` and add some ending `</font>` tags. Most probably these people have a serializer to XML.
