Xalan XPathAPI traverse question
I'm trying to parse a xhtml file using xalan XPathAPI. I'm stuck at the following requirement. Here's a snippet from the xhtml
<table border="0" cellspacing="0" cellpadding="0" class="cmnt_message">
<tr>
<td width="33" align="right">
<span class="cmnt_baloon"><!-- Image --></span>
</td>
<td width="767" class="red pad_l_10">

</td>
</tr>
<tr>
<td colspan="2" class="cmnt_text">
@rmaytee<br />
<br />
#2<br />
<br />
In 2011 it is possible to switch to old mat/map browser<br />
<br />
Just look around<br />

2 things:<br />
<br />
1- Please bring back "use object center as start snap point" in the snap settings. We have voiced our opinion about this, now please show us you care. <a target="_blank" href=
"http://www.the-area.com/forum/autodesk-3ds-max/autodesk-3ds-max--3ds-max-design-2011/use-object-center-as-start-snap-point">www.the-area.com/forum/autodesk-3ds-max/autodesk-3ds-max--3ds-max-design-2011/use-object-center-as-start-snap-point</a><br />
<br />
2- Make the Material/Map Browser the way it used to be. It is SO SLOW. At least make an option to switch to a "classic Material/Map Browser" or something.

I'm facing couple of issues here.
- I'm trying to extract the values of cmnt_message class. One is the "Posted By..." text under first block and the text content under cmnt_text. Here's the xpath for the first posted by part
/html:html/html:body//html:div[@class='content_d']/html:table[@class='cmnt_message']/html:tr[1]/html:td[2]/text()
This returns me "Posted by Macha on Mar 06, 2011 at 01:02 PM" which is what I want. But when I'm trying to get the cmnt_text with the following xpath expression
/html:html/html:开发者_JS百科body//html:div[@class='content_d']/html:table[@class='cmnt_message']/html:tr[2]/html:td/text()
I'm getting "@rmaytee" i.e. the value till first
. I'm trying to get the entire text inside cmnt_text.Other problem is I need to iterate through the cmnt_message and create a collection of Message object which consists of posted by and comment. Not sure how to iterate using Xpath.
SAX2DOM sax2dom = new SAX2DOM(); p.setContentHandler(sax2dom); p.parse(new InputSource(urlXML.openStream())); Node doc = sax2dom.getDOM(); XObject comment = XPathAPI.eval(doc,commentPath);
But this returns me only the first occurrence of the cmnt_message class.
Any pointer will be highly appreciated.
- Thanks
What you want is called string value.
If your XPath engine support string data type as result, you can use:
string(
/html:html
/html:body
//html:div[@class='content_d']
/html:table[@class='cmnt_message']
/html:tr[1]
/html:td[2]
)
Or select the td
element and use the proper DOM method.
It's not good to use text nodes for a mixed content model like XHTML.
You have to either use XSL or iterate over the child nodes of /html:html/html:body//html:div[@class='content_d']/html:table[@class='cmnt_message']/html:tr[2]/html:td
yourself.
