Import an HTML table using XSL
I have constructed an XSL file that parses an开发者_如何学JAVA XML formatted log and generates an HTML page with information from the log. In this same XSL file, I am attempting to use XSL to pull in an external HTML file that contains a table that I want to display. As it stands, I can display the entire page that contains the table, but am unable to isolate the table. How can this be done? Currently, I can pull in the entire page using the following code:
<xsl:copy-of select="document($tablePageUrl)" />
However, I don't understand how to traverse the HTML body and pull out a copy of the table. An example of how the HTML document is formatted (the document is proper XML, but not proper HTML):
<html>
<head>
</head>
<body>
<table>
Table Contents
</table>
</body>
</html>
Sounds like you want to use XPath to select a particular element in the document.
Try something like:
<xsl:copy-of select="document($tablePageUrl)/html/body/table" />
From comments:
I had tried using XPath but was using incorrect syntax
From http://www.w3.org/TR/xpath/#node-sets
The
/and//operators compose an expression and a relative location path. It is an error if the expression does not evaluate to a node-set. The/operator does composition in the same way as when/is used in a location path
In particular, this syntax:
document($tablePageUrl)/html/body/table
Following the production:
PathExpr ::= FilterExpr '/' RelativeLocationPath
FilterExpr ::= PrimaryExpr
PrimaryExpr ::= FunctionCall
Check to see whether the HTML is in a namespace. (Look for a telltale xmlns="....".) Your sample isn't in a namespace, but from experience, if people don't realise that namespaces matter, they often remove the namespace declaration when posting samples. If the elements are in a namespace, then the XPath expression needs to use prefixed names to select them.
<xsl:variable name="source-html" select="document('url')" />
<xsl:value-of select="$source-html//table" />
