import xml document into open office using xslt
Question
I am at the early stages of building an xslt document to import xml data into a libre office spreadsheet. The xml data represents a graph (with nodes and edges) in xgmml format. At this stage I am simply(?) trying to select all of the nodes in the graph, extract the "label" attribute, and place each label in a cell on a single row in the spreadsheet.
I am able to install the .xslt in libre-office and open .xgmml files.
I am able to use the .xslt to extract some data from the .xgmml and add it to the spreadsheet
But, For some reason I am unable to select the nodes and extract the label.
Can some-one please point out my (undoubtedly) silly error?

Because your graph element has xmlns="http://www.cs.rpi.edu/XGMML/" , all the unprefixed elements in your source XML are in this namespace, but in XPath expressions, an unprefixed name matches elements that are not in a namespace. Therefore you need to bind the http://www.cs.rpi.edu/XGMML/ namespace URI to a prefix in your stylesheet and use that prefix in the XPaths:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:g="http://www.cs.rpi.edu/XGMML/" exclude-result-prefixes="g">
<xsl:template match="/">
<!-- ... -->
<xsl:for-each select="g:graph/g:node">
<table:table-cell>
<text:p><xsl:value-of select="@label"/></text:p>
</table:table-cell>
</xsl:for-each>
<!-- ... -->
</xsl:template>
</xsl:stylesheet>
