Tokenize and REGex Question

bonekrusher · January 21st, 2010, 08:35 AM

Hi,

I have the following value for @id:

Code:

ctl00_ContentPlaceHolder1_PICList_gridPICList__1_1_2_3row

I want to tokenize by any letter [a-zA-Z] and underscore. In XML Spy, this regex works fine, but in Saxon 9-1-0-7 i get an error:

Code:

<xsl:value-of select="tokenize(@id, '([a-zA-Z])|[\_]')[47]"/>

Error:

Code:

Error at xsl:value-of on line 17 column 69 of 8900-2.xslt:
  FORX0002: Error at character 13 in regular expression "([a-zA-Z])|[\_]": invalid escape sequence

Any thoughts?

thx

I don't think the '_' needs to be escaped, simply try it without the backwards slash in front of it.

Some regex dialects allow you to escape characters such as underscore even though they aren't metacharacters - the XPath dialect doesn't

Some products allow you to use regexs that are illegal according to the XPath specification - Saxon doesn't.
