To create a cross-browser solution that is based on the IE-syntax check out Simple Implementation of selectNodes() and selectSingleNode() for FireFox [Mozilla] with a script which works very good.

Even simple tasks can be quite hard to find an answer to when trying to search. Most results are from newsgroups which is not always that relevant or self-explanatory. I will try to post some simple XSLT and X-Path tips every now and then.

This is how you do a simple sum in XSLT:

<xsl:value-of select=”sum(XPATH)”/>

If you want to sum all positive values:
<xsl:value-of select=”sum(//rs:data/z:row[@InvoiceOrderTotalWithTax > 0]/@InvoiceOrderTotalWithTax)”>

If you want to sum all negative values:
<xsl:value-of select=”sum(//rs:data/z:row[@InvoiceOrderTotalWithTax < 0]/@InvoiceOrderTotalWithTax)”/>

The xpath that is referred to here is generated from ADO.

In MSXML 3.0 you can set this property to “XPath” to switch the query language from XSLPattern to XPath. Once the property is set, there is no way to switch back without creating an instance of a new DOM object.

 

xmldoc.setProperty("SelectionLanguage", "XPath"); // JScript
xmldoc.setProperty "SelectionLanguage", "XPath"   ' VBScript

Second-level DOM Properties

This caused me many headaches until I found this solution. I have MSXML Parser 5.0 installed here (from Office 2003). Another colleague of mine encountered problems with the web-application I am currently developing. After some testing I noticed he had MSXML Parser 3.0 installed. A google search led me to MSXML DOM Tips page which revealed:

If you want MSXML3 to use XPATH instead of “MS patterns” in methods like selectNodes, you need to set the SelectionLanguage property
