Regex 选择数字前面的单词

我有以下XML数据

<para>The functions and duties of the CCS set out in s 6 CA are focused on promoting efficient market conduct and competitiveness of markets in Singapore. Consumer welfare, mentioned in the Singapore&#8211;US FTA, is not expressly mentioned as a purpose of the CA, nor is it expressly set out in the CA as an objective to be safeguarded by the CCS. However, CCS Guideline 1, at para 2.1 on &#8220;Purpose&#8221; of the CA makes reference to how consumers benefit as a consequence of competition. And this is equal to 2.1% of the entire data</para></footnote></para></item>

我想把

转换成下面的格式

                    <xsl:analyze-string select="."  regex="http://[^ ]+">
                        <xsl:matching-substring>

                                <xsl:value-of select="."/>
                            </a>

                        </xsl:matching-substring>
                        <xsl:non-matching-substring>

                            <xsl:value-of select="."/>
                        </xsl:non-matching-substring>
                    </xsl:analyze-string>

er:#BGCL_CH_x/Px-y

请让我知道我该怎么做

                    <xsl:analyze-string select="."  regex="http://[^ ]+">
                        <xsl:matching-substring>

                            </a>

                        </xsl:matching-substring>
                        <xsl:non-matching-substring>

                            <xsl:value-of select="."/>

谢谢

试试以下方法：

                                <xsl:value-of select="."/>
                            </a>

                        </xsl:matching-substring>
                        <xsl:non-matching-substring>

                            <xsl:value-of select="."/>
                        </xsl:non-matching-substring>
                    </xsl:analyze-string>
                </xsl:non-matching-substring>
            </xsl:analyze-string>
